“Nice little pH monitor. It works out of the box, and is even better when you purchase the pH probe holder that fits onto the side of the aquairum. It comes with the pH solution required to calibrate, and I tested them to compare, and they do read pH7 and pH4. Everything you need to monitor pH. It even comes with a double-sided tape fixture, allowing you to mount the lightweight unit without screws.
The only slight niggle is that the probe or unit has no 'smoothing', so the pH can jump around if there is any interference. However, it does mean it measures in absolute, real-time, so this is really a very minor criticism.
Overall, a nice kit and sits proudly mounted in my aquairum cupboard.”
“The device is compact and comes with everything needed including calibration fluids and a mounting bracket. The calibration is very sensitive and I am yet to know the accuracy as it's only been in use a couple of days. I will check against a pH pen for comparison.”
