Description
1/ 4 DIN panel mount pH controller, microprocessor based with membrane type keypad and password protection. Meter has a programmable, reversible and isolated 4- 20 mA current output and dual SPDT relays. Connectors are a BNC and spade lug terminal blocks. ATC is a 10K thermistor or simulation resistor. Features a NEMA-4 type bezel for watertight seals against mounting panels. 115/ 230V AC.
