Review on Professional Temperature Calibration Measurement Hydroponics by Tara Gardner
An accurate pH meter that works!
I bought this to control the pH in my tank and it works great. It's very accurate. The only downside is that after 2 days of continuous monitoring the batteries were low and only showing temperature and not pH. After plugging in the power supply, the ph indicator lit up again and has been working ever since. I would recommend this monitor for freshwater aquariums.
