Oakton CTSTestr™ 50C Cup-Style Waterproof Pocket Conductivity/TDS/Salinity Tester

Oakton CTSTestr™ 50C Cup-Style Waterproof Pocket Conductivity/TDS/Salinity Tester, Premium 50 Series is an underrated digital water tester. It seems to be a branded tester from Eutech which is an Australian company that makes some of the best digital testers out there. One of the key features of this tester is how easy it is to calibrate and how stable it is.

MORE ABOUT THIS ITEM

These CTS testers make measuring water quality easier and faster. The large display offers a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time. The testers are available in a pin-type or a cup style measuring sensor and measure conductivity, TDS, and salinity all in one instrument.

To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used—no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. The wider design provides a base to keep the meter upright for hands-free measurements. The keypad features a fourth key to simplify menu navigation while keeping convenient one-touch calibration. The housing is compatible with lanyards to prevent losing or dropping but is still waterproof.

I mention easy calibration because sometimes getting these digital salinity meters to read the correct salt level can be a challenge. Oakton makes it easy with this tester by allowing you to plus or minus the salinity reading to match the calibration solution. But calibrating the device is something you don’t need to do often because this is a very stable tester. 

It is a bonus that this tester also does TDS (Total Dissolved Solids. TDS is basically all of the stuff left behind when pure water evaporates. If you are wondering how to get an accurate TDS reading in a salt pool the equation is pretty simple. Take a Salinity reading. Takes a TDS reading. Subtract the Salinity from the TDS reading. Take a tap water TDS reading. Salinity – TDS = X.

X – Tapwater reading = TDS. 

Example: Salinity is 3200 ppm. TDS reading is 4500 ppm. True TDS is 1300 ppm. Tab Water has a TDS of 300 ppm. The total TDS of the pool is 1000 ppm

All in all, this is a great tester made by a solid company in Oakton.
