I must have two of the older version of the PH-200. The batteries in both our units consist of (3) button batteries stacked side by side horizontally within the battery compartment. I definitely wish we had the newer model that appears to use (2) standard AAA batteries in a flashlight-like compartment. Much cheaper than buttons and much easier to replace.

I accidentally calibrated 7.0 solution at 10.0 ph. How do I reset it to calibrate 7.0 buffer solution accurately? Do I have to do it in manual mode?
But u didn't explain about the "electrode storage liquid" why??
Is any video about how to use HM Com 300, pls?
what can be used in sea water ?
Hello. Is it possible to use it for lab purposes on corrosive solutions that go as high as 11 pH or as low as 1 pH?
Meu aparelho não quer ler a solução de ph 7 para calibrar o que pode ser ???
Can't find the probe replacement anywhere.
Esta en ebay 👍🏽
EU PRECISO DO HOW TO USE ORP-200
This is not a 'How to use' instruction, only calibration?
Yea considering using it consists of turning it on and sticking it in your water/solution. No other steps
So confusing, probably the most confusing PH Meter out there.
You're joking right? This thing is incredibly easy to use and much less hands on than the majority of similarly accurate PH meters out there.
@@blw9641 this was 2 months ago I now know how to use it 👍🏽
@@blw9641 lol it’s pretty easy
