No button/potentiometer to change current reading? Our hanna HI98121 get very wide error reading, pH 7.0 = 0.01. & pH 10 = 2.2 We can't make calibration on it. Unbelievable !!

@@HannaInc ok i thought so , but why doesnt it say it does in clear words ...because there is another one (number ending in 20) that says tempature ,this one does not ,its tricky salesmanship because the one that says tempature is more expensive ..... why do this?
@@khalilhannah4005 I understand what you're saying. The ORP/Temp Meter (HI98120) Only does ORP measurements. This meter will also measure pH and does specify Temperature on our site. Looking at this particular video, the title omits temperature, thought it does specify in the video. But good catch! The title has been changed. Is this something you're looking to buy? What are you testing?
@@khalilhannah4005 If you're trying to choose between the HI98120 and the HI98121, the only difference is the HI98120 is an ORP/Temp meter, and the HI98121 is a pH/ORP/Temp meter. Both have replaceable electrodes. Here's a link for more info on the HI98121. hannainst.com/hi98121-orp-ph-temperature-tester.html
After calibrating why does the (Cal) icon stay on? Should it?
And i don't have 7.01 or 4.01. I have a 7.0 and a 4.0. Should this bee good enough?
Demonstration is too fast
Difficult to understand ??
I have 98121 for last 2 years
How do I know its working ok?
I dont have buffer solutions
Why the meter unable to say. When to calibrate ?
Also i just calibrated it with 7.0 and 4.0 and right after it said ok its done it went from 4.0 to 3.86. Why is it doing this. It does it everytime.
I have one of your meters that is out of power. How do I change the battery?
Hi Robert! If you have a meter like this one, there are screws at the top. Remove those to access the batteries.

Como consigo um aparelho desse?
Hey Billy, these meters can be found at hannainst.com
does this probe check tempature as well as ph and orp?
Hi Khalil. Yes, this will measure all 3.
