1.0 out of 5 stars Unreliable and inaccurate, 23 Aug. 2010
This review is from: Pen Type pH Meter - PH-03
I purchased this product to use for testing the Ph value of my swimming pool. I found that the readings varied from 7.12 to 7.45, constantly changing. I don't have access to buffer solutions,(the instructions say you should calibrate it with buffer solutions regularly) though I did have a bottle of distilled water in my garage, which you need to clean the probe before use.

The second time I used it (the next morning) it wouldn't turn on at all. I checked the batteries- they were OK, but the display remained blank. It is useless. I live in Cyprus, and my son in law brought it out with him from the UK. I don't even think it is worth sending back under warranty, as it did not give realistic readings. I will go back to pool Ph test strips- at least they are reliable.
