3321/3331

Easy to install 1/8 DIN plastic casing.

Clear LCD displays conductivity, resistivity or temperature with backlight.

Universal power supply input from 100-240VAC.

Automatic or manual temperature compensation.

Two sets of programmable on/off relays for conductivity or resistivity (3321).

Isolated and reversible 4-20mA current output for conductivity or resistivity allows
it to be used as a proportional output (3331).

RoHS compliant.
