ORP Resolution	1 mV
ORP Accuracy (@20°C/68°F)	±5 mV
Typical EMC Deviation	±6 mV
Input Impedance	10^¹² Ohm
Dosage	Proportional, acid or base, user selectable
Dosing Contact	Isolated, 2A, Max. 240V, resistive load, 1,000,000 strokes
Alarm Contact	Isolated, 2A, Max. 240V, resistive load, 1,000,000 strokes
Recorder Output	4 to 20 mA (isolated)
Alarm Contacts	Terminals can be configured as normally open or normally closed (isolated output Max. 2A, Max. 240V, resistive load, 1,000,000 strokes). The alarm is activated if pH falls below the setpoint by the userselectable interval (0.0 to 2.0 pH), or conductivity exceeds the setpoint by more than the user-selectable interval (0 to 2.0 mS/cm) or due to overdosage
Probe	Any combination pH electrode with a universal BNC connector and Hanna Conductivity 4-ring potentiometric probe with built-in temperature sensor and DIN connector (optional)
Dosing Terminals	Two sets of independent terminals (115 to 240V, Max.2A, 1,000,000 strokes) are activated whenever pH exceeds the pH setpoint and/or conductivity falls below the EC setpoint
