3621/3631

Easy to install 1/8 DIN plastic casing.

Clear LCD displays pH, mV or temperature with backlight.

Universal power supply input from 100-240VAC.

Automatic buffer recognition of US and NIST buffer sets. Calibrated data is stored in memory and ready to for use on power up.

Automatic or manual temperature compensation.

Displays absolute and relative ORP.

Two sets of programmable on/off relays for pH or ORP (3621).

Isolated and reversible 4-20mA current output for pH or ORP allows it to be used as a proportional output (3631).

RoHs compliant.
