Online Residual Chlorine Monitor BH-CL650
The online residual chlorine monitor BH-CL650 can realize continuous and accurate measurement and control of residual chlorine value (free chlorine), hypochlorous acid value (HCLO), pH and temperature values. The instrument is equipped with membraneless electrode method online residual chlorine electrode, pH electrode and special flow cell. No reagent consumables consumption, easy installation and maintenance. Widely used in tap water, RO water, hospital wastewater, residual chlorine generators, swimming pools and other residual chlorine monitoring occasions.
Feature
- 128*64 dot matrix LCD display, IP65 dustproof and waterproof
- Calibration with DPD colorimetry
- RS-485 interface, photoelectric isolation processing, safe and reliable
- Two switch control relays, one function relay
- Two 4-20mA isolated current outputs, temperature reading offset adjustment
- The instrument can connect and measure pH and residual chlorine at the same time, and perform pH automatic compensation for residual chlorine
