The models 3675 & 3676 are precise instruments for the measurement and control of pH
and mV (ORP).

Two output relays are provided for ON/OFF control. The isolated 4-20 mA current output
covers the input control range of 0 to 14 pH and 0 to 1400 mV.

Both models are housed in a rugged 1/4 DIN plastic case. This allows the meters to fit
into standard panel cutouts, while providing industrial weatherproof and environmental
housings.
