JENCO In-line pH Meters pH, ORP In-line Controller 3679N

Description 1/ 4 DIN panel mount pH/ ORP controller/ transmitter in a waterproof IP-65 enclosure. Features, LCD display, dual SPDT Hi/ Lo relays, manual set point adjust and pH calibration via potentiometers. For ORP there is a Zero Adjustment and pH/ ORP is selectable via a shorting plug. Output is 4-20 mA current type. Connectors are a spade lug circular connector for pH+ . All other connections are tinned leads to terminal blocks. Temperature compensation is a Pt-100 ATC or simulation resistor. Power 115/ 230V AC. * Dual function pH & ORP * Orp zero point calibration * Isolated 4~ 20ma output * Dual on/ off relays * Auto temperature compensation * Water & corrosion proof case * Large led display Specifications pH Range : 0.00 to 14.00 pH Resolution : 0.01 pH Accuracy : 0.1% ± 1 LSD ORP Range : -1999 to 1999 mV Resolution : 1 mV Accuracy : 0.05% ± 1 LSD # Outputs * Relays output ( max.) : 5amp. at 115VAC, 2.5 amp. at 230 VAC, resistive lo * Relay hysteresis pH/ ORP: ± 0.1ph/ ± 10 mV * Isolated 4~ 20mA output range: Over imput span * Accuracy: 0.1 % of span * Isolation voltage: 500VDC max. * Load resistance: 500 ohm max.
