Simple and reliable

This meter is easy to calibrate, and tends to hold calibration longer than others I've used. Good value for the price!

Very Good for the Beginner Aqu

This meter is a very good buy for those just starting out as an aquarist. The meter really needs to be submerged well into the water, to the gasket line, and in the mid third of the tank for the most accurate reading. I have also found that I need to submerge two times in two different locations of the tank (I have a 65 gallon reef tank) for absolute assurance of consistency in the readings. Overall, I think this is a great teaching tool as one begins to learn the science and execution of monitoring devices, their purpose, and ease of use. While other meters are less expensive, I have found this device (the third one I have tried) to be the easiest to use and provides the exact data I need. If I were to criticize anything it would be the instructions. I don't believe that is necessarily attributed to just this meter, however, as I have seen poorly written instructions accompany many aquarium devices.

what to watch for

Make sure the probe has liquid in cap when you open it. Also make sure the extra vial has fluid in it. Mind came dry.

Great

Works like a charm. Easy to understand and use. Very convenient way to spot check parameters without having to carry around a probe and box like other monitors. Price was right!

HM PH Meter

I knew very little about PH Meters and thought this was going to be an easier way to check the PH in my display tank. It is not easier, but it is more accurate. It will need to be calibrated with both a 7.01 and 10.01 PH solution (at least twice a month). I recommend buying PH probe storage solution, and extra 7.01 and 10.01 calibration fluid. The temperature gauge on this unit is not accurate and you will get fluctuations of 3-5 degrees. If you are using it solely as a PH probe (not temp) and don't mind calibrating the unit often, then it is a good economical unit.
