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 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.
