HANNA BL7916-1 pH Controller & Dosing Pump, Accuracy: pH ±0.01, Flow Rate (LPH): 7.8 to 13.3, Electrical: 115V

pH Controller/Dosing Pump Description: • pH controller and dosing pumps in one compact unit.• ±0.01 pH accuracy with unbeatable performance.• Isolated 4 to 20 mA recorder output.• Proportional dosing slows the pump down when the measured pH level approaches the set valve which ensures precise dosage and avoids costly waste of chemicals due to over dosage.• Alarm contact is activated whenever the pH value varies more than 2 pH units 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: 0.00 to 14.00 pH Resolution: 0.01 pH Accuracy: ±0.01 pH Flow Rate: 13.3, 11.7, 10.1, 9.0, 7.8 (LPH) Input Impedance: 10(12) Ohms Dosage: Proportional, acid or base, user selectable Calibration: Offset: ±1 pH with trimmer; slope: 85 to 115% with trimmer 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 #: BL7916-1. The BL 7916-1 pH Controller with dosing pump is supplied with discharge and suction valves, polyethylene tubing, power cable and instructions.
