Pen Type Salinity & Temperature Meter ATC NaCl Salt Water Quality Tester for Saltwater Aquarium Hydroponics Food Salinity Meter (70.0ppt)

Great Purchase

Fairly accurate using a certified calibration soln of 35ppt I got 34.6ppt but I got 35ppt with my hand held refractometer. So will use for general checks on my reef tank

Great meter. Easy and consistent readings!! Thank you.

Instructions could be better but seems ok.

Batteries rusted, probably leaked and do not work. Now I have to go and buy a set. Not great.

Using this to test swimming pool water

Ideal and easy to use for my koi pond, takes the guessing out..!

Arrived, was not calibrated, well might have been calibrated as did not give consistant readings. Couldnt trust it and was not prepared to start buying calibration fluids for something that was providing spiradic readings.Instructions were also over complicated.
