CHECKIT^® micro WP
Determination of: pH, Redox, Conductivity, TDS, Salinity and Temperature (waterproof)

The new CHECKIT^®micro WP series is a range of waterproof and dust-tight (IP67) units for determination of pH value, redox, conductivity, TDS, salinity and temperature. The compact, robust housing and the electrode replacement option meet the high standards required of state-of-the-art technology.

All units are equipped with an automatic switch-off and a "Hold" function which "freezes" the result in the display with a single key-press. The range includes several versions with different measuring ranges and levels of accuracy for different applications.
