The Model AB4081 measures conductivity, resistivity, salinity, total dissolved solids
The Model AB4081 measures conductivity, resistivity, salinity, total dissolved solids and temperature of aqueous solutions with just one cell. The enclosure features a smooth, splash proof front panel design with easy to use keypad switches. Automatic temperature compensation (ATC) can be turned on or off.

The display is an easy-to-read sixteen character by 2-line liquid crystal dot matrix. A low battery message indicates when a fresh battery is needed and an auto off feature will extend battery life.

Accessories available include a Lab stand for bench top use; a soft field carry case or a Function Verifier. Made in USA.
