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.
