JENCO pH, ORP, Temperature In-line Controller 6503

Description 1/ 4 DIN panel mount ORP controller/ transmitter, microprocessor based, password protected with membrane keypad. LCD displays ORP or pH and temp. Meter has dual SPDT Hi/ Lo relays, with programmable hysteresis and a reversible, isolated and programmable 4-20 mA output. Connectors are dual BNC for pH/ ORP and spade lug type. ATC is 10K thermistor or simulation resistor. Power 115 / 230V AC. * Controls ORP & measures pH * Offset calibration for ORP * Set point security code protection * Dual on/ off relays * 0.5 high LCD display * Auto/ manual temp. compensation * Power down memory backup * Audio feed back touch keys * 1/ 4 DIN housing Specifications pH Range : -2.00 to 16.00 pH Resolution : 0.01 pH Accuracy : ± 0.01pH ± 1 digit ORP Range : -1999 to 1999 mV Resolution : 1 mV Accuracy : ± 0.1% ± 1 digit Temp.
