Great pH Meter
About Me Academic/Professional Researcher
Great pH Meter. Con pH element has to be replaced from time to time, but that is true with all pH meters reguardless of maker. pH 30 gave great reading, but user must read instructions and learn to use the meter. I have owned the pH 30 for Six years and have replaced the pH element twice. I would purchase this pH 30 Meter again.
Bottom Line Yes, I would recommend this to a friend

pHone Tester 30 challenges
I found it difficult to calibrate the temperature accurately. Also, the calibration seem to go off to easily just a day later. Not sure if I can trust the reading on the same product on the next day. It would be good to have a help line to call when using the device to ensure is being done properly.
Bottom Line No, I would not recommend this to a friend

Read, read, read directions. When one does, it's accurate and easy to use. I have used it in different situations. I have found that the more it is used, the accuracy lasts much longer, i.e., two dozen uses. Inactivity requires, less than three uses per week, calibration each time. and, to use the old addage, that's the best money I have ever spent...Brett

Great little cost effective tool!
By Water Lady
from Baytown, Texas
As a Water Lab Technician in Baghdad. It fell to my department to test potable water systems daily for the US Military. Our crew was primarily low skilled workers from various countries with little to no English skills. These meters were perfect for that environment. The only problem we ever encountered was in changing the electrode. It is critical that it be done in a dry environment and that the seal be set just snug. Over tightening would cause the seal to leak thus ruining the electrode and the meter. Once the seal is snug a perminant marker line across the joint will give you a visual reference that the seal is still in proper position.

A good product
from New Haven CT
We use 15 of these for 3 weeks in the field each summer. Completely untrained students use them on streams, and we intercompare results. The mean difference is 0.10 pH units and the median 0.065. I consider that to be excellent. After 4 years we had to replace all of the electrodes, perhaps because they sat dry most of the time, though this is recommended storage by the manufacturer.

Good, solid meter
used in the field every day in an industrial setting and it's been the most reliable meter we've had over the years. Our first one lasted three years and we will buy another one.

PHTESTR 30 used in Lab Animal Water
By Frank "The rodent microbiologist"
from Tewksbury Mass
I use this product to check the Ph of Laboratory animal drinking water(Rodents). The Ph of the animal drinking water needs to be in the 2.0 to 3.0 range . The PHTESTR 30, WATERPROOF, DJ, WITH TEMPERATURE READOUT pHTestr works very well in this range.
