JENCO 6503, PH, ORP, Temperature In-line Controller

Model : 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 : * Range Resolution Accuracy pH -2.00 to 16.00 pH 0.01 pH ± 0.01pH ± 1 digit ORP -1999 to 1999 mV 1 mV ± 0.1% ± 1 digit Temp. 0 to 115 ° C 0.1 ° C ± 0.2 ° C ± 1 digit * Current Output o Isolated current output: Reversible & programable 4 to 20 mA o Isolation voltage: 500V DC maximum o Transmitter load: 550 ohms maximum General o Input impedance: > 10exp( 13) ohms o Default ORP buffer: 86mV o Temperature compensation: Auto/ manual ( thermistor 10kw at 25 ° C o pH buffer recognition: 4.00. 6.86. & 9.18 o pH slope recognition: ± 30% o Relay output ( resistive load) : 5amp at 115V AC or 2.5 amp at 230V AC o Relay set point hysteresis: User programable o Power failure back up: Yes o Power source: 115V AC or 230V AC, 50/ 60 hz o Weight: 750 grams
