Wrks really well – 2.0" LCD Digital Folding PH/Temp/Humidity Tester (4 x AG13) Reviews

posted by CidCampeador on 04/06/2012 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Pros:
-Works really well, very precise -Also has temperature and humidity sensor -Auto turn-off saves batteries -Calibrate it using a buffer solution (Not included) or distilled water at pH 7.0-7.1pH -Glass electrode
Cons:
-You HAVE to calibrate it every time you use it. Otherwise, you will get bad readings (not really a con, says it in the manual) -Open it slowly so the electrical connections don't get damaged -The last pH digit is useless, because the precision it's just +-0.1 PH, so just dont pay attention to it
Other:
Its a really good tester, looks very professional and works very well. Only for liquids.
Bottomline:
You HAVE to buy a buffer solution for calibration ad calibrate every time you use it.
