Accurate reading.
When I first started using the meter every time I took a reading I had to calibrate the probes each time I used it, now I keep the probe in the aquarium on a permanent basis it saves a small fortune on buying calibration powder and distilled water, also gives a more accurate reading than the coloured chart type of tests.

Easy to calibrate. Reliably consistent
The first unit I purchased had a faulty probe which was disappointing but worked perfectly with a new probe. I have since bought two more units and all three are installed in different locations. All perform very well. The device calibrates easily. Response time is good. The display is easy to read and can be backlit. The device is compact and easily installed. I would recommend this device for its design, performance and price.

Doesn't work properly, keeps freezing. Screen malfunctions. Can't seem to get a replacement. Probe broke very quickly. Bought a replacement. Realised the unit was dodgy too. Waste of money. Would like a refund.

Happy with this unit. It wasn't factory calibrated, but since calibration, it's been rock solid. Would recommend.

Mains powered with battery back up
Really nice small unit that is mains powered and shows bright Ph and temp numbers on a green background. Being mains is stays on 24/7 unlike my other monitoring unit that is only battery powered so I try to keep it off. Use the Ph testing solutions to know how the unit reads. Both my units monitoring read under by 0.5. Doesn't have a good way to hang it up. Has a sticky tab that falls off from a U carriage. Needs a couple of slots to secure it easier with zip ties or hooks. But really like this small unit. Quick to react to water changes immediately. Like it.

Preciso
El tercero que compro y me encanta lo practico que es abrir la puerta del sump y ver el pH y temperatura sin tener que hacer nada
