About Gain Express Digital Combo pH & Temperature Meter, Aquarium Thermometer pH Monitor
Overall Feedback:
79% positive
77% praised for its high accuracy readings
I have tested the pH meter with a test kit and it is accurate, showing the same results as this item.
The meter turned out to be much more accurate than I initially expected.
75% liked the clear and easy-to-read display
I am happy with the display clarity of the PH meter and can easily glance at it to get what I need.
80% found calibration to be straightforward
I find that the unit calibrates easily and registers the same measurements as my expensive blue lab.
I used to calibrate the probes every time I used the meter. Now, I keep the probe in the aquarium permanently, saving money on calibration powder and distilled water. This method also provides a more accurate reading than the colored chart type of tests.
65% appreciated the durable sensor
The blue lab is small, robust and has held its calibration for several months without any drift on calibration liquid checks.
85% praised for its water resistance
I didn't know if the device could be left in water before buying it, but now I'm leaving it in the water and it's working fine.
