Fine instrument
I bought the pH400S to monitor the pH and ORP of my pool. I like its ability to record data over extended periods, which allows me to measure chlorine demand periodically. I hope the device lasts. I'll update my review if it breaks down prematurely, but I'm optimistic it won't.

The company should have tested the machine for shipping it!!!
The instrument worked well for finding the Ph levels it was accurate, however the TDS was way off, the result was wrong, I compared it with other machines that I had. That said My machine was new, I made the tests on the first day, and because of the wrong results I returned the instrument.

28 pages of ditrections
Simply the worst pH meter that I have ever encountered. Nothing is simple. You cannot turn it off by hitting the power button alone. You need to hit two separate keys in order to turn it off. The directions are 28 pages long. That should tell you something. Calibration requires that you choose the 7.0 ph standard "first". If you do not good luck.
