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.

Working pH probe

Could not calibrate, did not work
This item did not work. I was unable to calibrate to ph 7.0 or 10.0. Every time I tried to increase the value it would reach 4.5 but then automatically drop to 3.5. Would not go higher than 4.5. Same value displayed when the ph probe was detached from the unit. Had to return it. Waste of time and money.

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

Totally Inaccurate Readings
PH Sensor will not calibrate correctly in test buffer samples - inaccurate PH readings received.7.0 buffer reads as 4.0, 10.0 buffer reading as 7.0 amd 4.0 buffer does not even show a PH reading.Returned for refund.I guess, you get what you pay for...
