Details
ORP Controller/Dosing Pump Description: • ORP controller and dosing pumps in one compact unit.• ±5 mV accuracy with unbeatable performance.• Isolated 4 to 20 mA recorder output.• Proportional dosing slows the pump down when the measured ORP level approaches the set value which avoids over dosage of oxidizing or reducing agents.• Alarm contact is activated whenever the ORP reading varies more than 200 mV from the set point.• Auxiliary contacts allow the user to attach a mixer or priming pump that is activated only when the pump is dosing.• High Quality materials are used for all parts that come into contact with liquid. Range: -999 mV to +999 mVResolution: 1 mVAccuracy: ± 5 mVFlow Rate: 13.3, 11.7, 10.1, 9.0, 7.8 (LPH) Input Impedance: 10(12) Ohms Dosage: Proportional, Oxidizing or Reducing, User-Selectable Recorder Output: 4-20 mA (isolated) Dosing Contact: 1 isolated contact, 2A, Max. 240V, resistive load, 1,000,000 strokes.Alarm Contact: 1 isolated contact, 2A, Max. 240V, resistive load, 1,000,000 strokes.Power Supply: 115VEnvironment: 0 to 50°C (32 to 122°F); RH max 95% non-condensing Dimensions: 181 x 221 x 142 mm (7.1 x 8.7 x 5.6") Weight: 5 kg (11 lb.)Hanna #: BL7917-1. The BL 7917 ORP Controller with Dosing Pump is supplied with discharge and suction valves, polyethylene tubing, power cable and instructions.
