The N-770 is a general purpose, simple to use pH/mV monitor in an IP-66 waterproof enclosure with high and low trip outputs. The front panel gives clear indication of the process variable on a large 12.5mm LCD and trip point activity is indicated by bright LEDs.

All controls and connections are easily accessible inside the enclosure preventing interference by unauthorised personnel.

As standard, all monitors have a non-isolated 0-2V analogue output for recording purposes. An isolated 4-20mA current output option is available on the N-770/C .

The monitor is fitted with a high impedance reference facility. Used with appropriate Reference and Ground electrodes this facility will assist in some applications where the reference electrode is being harmed in use
