PH Meter
Description
Widely used in plating, wastewater treatment, water treatment and swimming pools, the BL7916 provides convenient installation, ease of use and maximum reliability.
- Easy Installation: Designed with mounting holes built into the base and front-facing controls and pump assemblies
- Proportional Dosing: Slows the stroke rate as the measured value approaches the user selected point, avoiding overdosage
- Rugged Construction: Rugged, fiber-reinforced polypropylene IP55 rated casing; parts with chemical contact made of PVDF, FPM/FKM and PTFE
- Isolated Recorder Output: To enhance troubleshooting and the ability to record data while monitoring the application
- Simple Pump Action: A positive displacement solenoid with few moving parts with no rotating parts, gears or cams to drastically reduce mechanical failures
- Auxiliary Dosing Contacts: Allows the user to attach a mixer or priming pump that is activated only when the pump is dosing
Chemical Dosing Pump Specifications:
- Alarm Relay Set Point: 1 isolated, 2A, max. 240V, resistive load, 1,000,000 strokes
- Dosing Control: proportional, acid or base, user selectable
- Analog Ouput Signal: 4-20 mA (isolated)
- Dosing Terminals: 1 isolated, 2A, max. 240V, resistive load, 1,000,000 strokes
- Over Current Protection: 250V fuse
