@UCXq7lamkJH9i5ogNuTLchaA it's to do with the units the formula uses and the readout on your meter.
1 mS/cm = 1000 µS/cm.
Ideally it should be in S.I. units - S/m but to save on 0's before a decimal point it's simplified.
According to the very small manual that comes with it you CAN calibrate it. The following is copied from the manual:
1) Put the TDS and EC meter into the standard solution, read the TDS value and compare the standard solution parameters. If there is deviation, manual calibration is required.
2) Open the TDS and EC meter screen protection film sticker ( you will see the small pushbuttons underneath this) and use a screwdriver to manually calibrate the calibration screw. Rotate the reading clockwise to increase the reading and counter clockwise to decrease the reading.
3) Calibration is then complete.
I just bought this and tested my mains water and shows my water to be very hard. Not sure how accurate this is but need to get another stick kit as a second opinion as not too confident the initial measurement from this device is accurate.

Where on earth is the calibration screw?
@@boncreationsza 1413 calibration solution,,,,come again now what's dat
Hi, thanks for the video but I have question. How do I convert the ppm in tds?
Hi, I have read some where that 1 EC = 500/700 ppm. What is this video showing the ppm reading half of the EC?
Ok everybody hold the shift button down it will start flashing put your pen in a known solution then press hold button in and out to go up press the on off button to go down to the required number and press the shift again and it is done and you can buy EC set solution eBay etc.
You are the MAN!
Number one!!!!!
Why has mine started showing 8056ppm when 2 days ago it showed 70 ppm now i cant get off this x 10
Under the black film there is a little screw for calibration.
I peeled the black film and drilled a small hole in it to get an access to the screw.
You need a standard NaCl (salt) solution in order to calibrate the EC meter.

How do you read this thing?
Google says 1 ec = 1 μs/cm which is what this metre reads in, so therefor 0088 should be 88 ec right? I havent calibrated it yet but this doesn't make sense to me. It also says tds/ppm = ec * 1000 / 2 or ec = ppm * 2 / 1000
so my tap water reads 0044ppm and 0088ec
So (88 ec * 1000) / 2 = 44000 ppm
Or
(44ppm * 2) / 1000 = 0.088ec
Please help I'm so confused
Could you please tell which way the battery is installed? (+ and - terminal of battery)
It's not shown in the leaflet that came with the meter.
The + side of the battery toward the metal tab and - toward the PC Board.
Can this determine 70 - 80% salinity?
May I know how deep it is allowed to put this in the liquid
For calibration it states ' calibrate with NsCi)
28.9 it a clean normal?
How is the volory to clean water?
Thank you, some of your big words fuvked me up but thanks
Hi, what is the alkalinity number??? Thx
Hi!!
How can I calibrate it? I have seen that the SHIFT key must be held down for a few seconds. I've tried and can't get into calibration mode. Thanks!!
any luck??

Hi i have a question...i read somewhere that 1 microsiemes/cm = 1 EC (Electrical conductivity) and i read that Yaraliva Calcinit fertilizer require 1.0 EC to apply to the plant ...but looking at your TDS meter just the water already reads by value of hundreds which is way out of the Yaraliva Calcinit application...would you mind to advice my lack of knowledge :)...why water have so much EC compare to the fertilizer...thank you in advance
I’m not an expert in that area but here is a link to a site that talks about the EC of nitrate-nitrogen in fertilizer.

You want reverse osmosis system I think
1000 EC should read around 500 ppm
Thank u
thank you!
How to reset to factory Settings, I get x2 in the display panel I dont know what I did now don't works !!
But what's the numerical threshold in which it becomes unsafe to drink the water that's tested? Above 100, 200, or what?
Here is a link to a website that list levels of TDS and ratings.
www.safewater.org/fact-sheets-1/2017/1/23/tds-and-ph
And all these times I've been wasting rain water..is rated at 6. My tap is 96. Rain taste a little raw maybe without chemicals. Love to check the water in restaurants.
So you can’t calibrate these, how long do they last before you have to replace it
You can calibrate it. You need calibration solution first of all. This meter is calibrated using the Hanna (ppm 500) scale. Hold down the shift button and use the top/bottom buttons to move the value to the closest to the calibration solution. Then press "hold". That should calibrate it.
so i got the following :
Kitchen :
0082 us/cm and 0041 pPM
bathroom :
0100 us/cm and 0050 ppm
does this sound right to
I’m not an expert but the reads look acceptable. Only thing to remember is it does not test well for organic compounds.
@@marlinjones5163 so how do get the ec. The course im take are like ec of 1 or 2 how do I get to that number
why e-1 portable tds & ec meter reading is always 1100 ?
Try cleaning the tip with distilled water or replacing the batteries. If that does not fix the problem it is probable a bad part.
Is the battery replaceable ?
Thanks for instruction, I use this measure to test the Sodium Hypochlorite Generator water, after i generate sodium hypochlorite water the test result are PH is 7.9, and PPM is around 6000PPM, 1026 us/cm, regular kitchen water PH is 8.75m, PPM 500PPM. I feeling this Sodium Hypochlorite Generator water made hazardous chemical, Am I right? please tell me professional advices
Invest in a reverse osmosis system
goo dayy what do i do if Ec value os carried with X10 on the top??
your help would be very much appreciated. I holded shift in effort to calibrate after i pressed off then the EC values disappered and all i could see is ---- i pressed shift and the values returned but they were now carried with X10
Remove battery and replace or change battery
You calibrate these devices with known solutions
Read top line Jeff
Thanks
0346 EC is 0.3 EC right?
EC = electrical conductivity, the 0346 on the display is the measurement is in microSiemens, 0.346 would convert to milliSiemens
@@mpjaonline got it! thanks for clarifying. cheers!
Αγορά που μπορούμε να κάνουμε ;
We fund out that without proper calibration the measurement of this device are not reliable enough.
How do you get rid of the 10x
Remove battery and replace or change battery
10x means you multiply the displayed value by 10.
I bought exactly the same and I thought there it can measure PH level which was the main reason I bought this. But I don't know why there is no PH level!
because pH Stick are badly made.. they always need adjustement with the powder. 3 kind of powder + distilled water to adjust the shit stick.
If you really need to test the pH, use something electronic that doesnt need to be adjusted.
Wrong! Your TDS meter needs to be calibrated periodically to remain accurate. The calibration
process involves dipping the TDS meter into a calibration solution. This solution is
formulated to a specific TDS range. The calibration process provides the TDS meter with
an accurate reference point. In other words, the meter learns how to interpret a wide
range of TDS level based on the reference level it “learned” during the calibration
process. All TDS meters “forget” their reference levels and need to be recalibrated
periodically. If the meter is not calibrated occasionally it will still provide a TDS reading
but it probably won’t be as accurate.
The newer model has a calibration screw.
What is the calibration process? Why is 1413 solution no longer provided with the shipped meters?
Hi , can u show how to install the batteries and what batteries please
The + side of the battery toward the metal tab and - toward the PC Board.
Yeah, this is what I do for entertainment purposes.
Ppm calibration solution, find it on ebay 🙂
How to calibrate?
Sorry there is no calibrating this model tester. It is factory set.
@abdou Ngotto It is calibrated at the factory.
Hold the centre button for 8 seconds to enter calibration mode

@@jayDotFishing01 Swimming pool chlorine generators (also referred to as salt water pool chlorinators) create chlorine in the pool water directly, removing the need for users to manually add chlorine- based chemicals to the swimming pool. Free available chlorine is continuously produced at a level which is automatically controlled. This also has the benefit of removing the need for storage and transport of chlorine-based chemicals.
However, as with any equipment, the chlorine generator must be maintained regularly to prevent fouling.
Most chlorine generators require a salt content of 1,500 - 6,000 parts per million (“ppm”) as sodium chloride (NaCl) in the swimming pool. In comparison, sea water has a salt content of around 35,000 ppm and humans have a salt taste threshold of around 3,500 ppm.
There are two types of salt water systems, one ‘in-line’ and one ‘off-line’.
Off-line Chlorine generators
Sodium chloride is added to a bulk storage tank to produce a saltwater brine solution which in turn is fed into an enclosed electrolytic cell. The liquid chlorine that the cell produces is then injected into pool water as needed. Sodium hydroxide and hydrogen gas are generated and removed from the system and don’t get added to the pool water.
Salt Water Pool Maintenance
Testing routine
Salt Concentration or Salinity - An efficient salt water chlorine generator requires salinity to be maintained at a constant level as defined by the manufacturer (typically 1500 - 4500 ppm). It is often recommended to test salinity in the pool weekly. Most salt chlorinators will display a salt reading. However, it is a good practice to test the salt in case the system needs to be recalibrated. If the salt concentration is too high, it can cause damage to the cell and other pool hardware. This can cause serious issues and the only way to adjust the salinity down is to add fresh water. If the salt levels are low, it could also lead to an unsanitary swimming environment because there won’t be enough chlorine produced.
Chlorine levels - The free available and total chlorine levels should be monitored and tested frequently. If free available chlorine levels are low, the salinity levels may not be sufficient and the generator performance should be checked. Low levels of free chlorine can also be caused by calcium hardness build up on the salt cell, an expired cell or inadequate pool circulation.
pH - As with non-salt water pools, maintaining an appropriate pH level is important for enabling the chlorine to work effectively and remove germs and bacteria.
Total Alkalinity - Total alkalinity is important to keeping the pH stabilised and prevent ‘pH bounce’. Low alkalinity can cause corrosion, staining or green water while high alkalinity can cause cloudy water and fluctuating pH.
Stabiliser or Cyanuric Acid - Stabilisers are used for outdoor pools as UV light breaks down the chlorine residual. An outdoor salt water pool requires higher levels of cyanuric acid than a regular pool and should be in the range of 60 - 80 ppm. This is to ensure the chlorine that is generated by the cell is not immediately degraded by UV from sunlight.
Calcium Hardness - If calcium levels are too low, the water can become corrosive and can leach calcium from plaster, stone and concrete surfaces in contact with the pool water. High chloride levels such as that seen in saline pools have been associated with a higher solubility of calcium carbonate. High levels of calcium can result in scale formation or a clogged filter and pipes resulting in poor filtration and circulation that can lead to cloudy water and irritation to swimmers.
Total Dissolved Solids (TDS) - The Total Dissolved Solids for a salt water pool will be higher than a regular pool because of the way TDS is measured. In salt pools, a TDS value of 4000ppm is more common and this must be measured in order to ensure the Langelier Water Balance Calculation can be carried out accurately to prevent scaling and corrosion.
Water Balance - To check the overall chemistry in the salt water pool, the Langelier Saturation Index (LSI) should be tested. This formula uses TDS, total alkalinity, calcium hardness, water temperature and pH to help control the risks of scaling or corrosion. It is common to calculate the LSI and subtract 0.1 from the answer in saline pools, this is to take account of the corrosiveness of the high chloride level.
Usefull information - ZERO!
Yeah I would have to watch the video again which I'm not going to do. But I think that the meter contradicted itself.
