Product Description

BL7917 ORP Controller and Dosing Pump is a compact, integrated solution for precise automatic chemical dosing based on oxidation-reduction potential (ORP) measurements. Designed for critical industrial applications such as plating, wastewater treatment, water treatment, and swimming pools, the BL7917 offers both measurement and dosing in a single, easy-to-install unit with all controls accessible from the front panel.

This instrument features proportional control that dynamically slows the pump's stroke rate as the measured value approaches the user-selectable set point, significantly reducing the risk of overdosage and excessive chemical use. The LCD display allows clear visibility of key performance parameters while its IP55 enclosure ensures robust operation in challenging environments.

Combines real-time ORP monitoring and chemical dosing for efficient process management.
Automatic proportional dosing enables cost-effective and accurate chemical addition.
User-adjustable oxidizing or reducing function guarantees flexibility in various process settings.
Advanced relay and analog output functionalities for integration with industrial control networks.
Built-in mounting holes and front-facing controls simplify installation and maintenance.
Applications span plating, water and wastewater treatment, and commercial pool management.

Industrial and laboratory specialists rely on BL7917 for reliable dosing solutions, process stability, and regulatory compliance. Explore more process controllers and dosing pumps in the EnvMart catalog for tailored measurement and control solutions.
