Product Highlights

  • HI 9912 is a 2-in-1 pH and ORP controller specially designed for pool control
  • Two separate set points can be user-adjusted from 6 to 8 pH and 500 to 900 mV
  • The relays are activated when the pH exceeds or the mV falls below the relevant set point
  • HI 9912 accepts any pH and ORP electrode ending in a universal BNC connector
  • Two independent terminals provide for pH and ORP ground probes to eliminate interference and prolong the electrodes' lives
  • Range pH 0.00 to 14.0 pH
  • Range mV 0 to 1000 mV
  • Resolution pH 0.01 pH
  • Resolution mV 1 mV
  • Accuracy pH ±0.02 pH
  • Accuracy mV ±5 mV
  • Input Impedance 1012 Ohm
  • Calibration - manual, 2 point for pH and 1 point for ORP through trimmers on the front panel
  • Setpoint - 2, selectable from 6.00 to 8.00 pH and from 500 to 900 mV
  • Proportional Control - adjustable from 0 to 2 pH and from 0 to 200 mV, time cycles from 0 to 90 seconds
  • Dosing Contact - 2 powered terminal for pH and ORP correction (115 or 240 V) Max. 2A, 1,000,000 strokes;pH dosage: activated when pH > setpoint; ORP dosage: activated when mV reading < setpoint
  • Alarm Relay - 1, activity when pH varies more than selectable value (0.5 to 2.5 pH) from setpoint or when max dosage time for pH (adjustable from 1 to 10 minutes) elapses; or activated when mV reading varies more than a selectable value (50 to 250 mV) from setpoint or when max dosage time for ORP (adjustable from 1 to 10 minutes) elapses (isolated, Max 2A-240 V, resistive load, 1,000,000 strokes)
  • Power Supply 110/115 Vac ±10% or 220/240 Vac ±10%; 50/60 Hz
  • Environment -10 to 50° (14 to 122°F); RH max 95% non-condensing
  • Dimensions 221 x 181 x 86 mm (8.7 x 7.1 x 3.4")
  • Weight 1.6 kg (3.5 lb.)
