The DP2030 residual chlorine monitor is an intelligent monitor consisting of an electronic unit (transmitter) with display and a measuring cell (with built-in chlorine electrode, pH electrode and temperature electrode) connected by cable. Used to monitor residual chlorine in water, such as drinking water treatment plants, drinking water distribution networks, cooling water, etc. It is also suitable for monitoring the chlorine content in water during the hospital disinfection process. Main Specifications: 1. Measurement range: 0~20 mg/L; temperature: 0~60 °C. 2. Automatic temperature compensation range: 0~60°C (reference temperature 20°C) 3. Detection limit: <20mg/L residual chlorine or <10mg/L HOCL 4. Repeatability: <±2% of measured value or <±5μg/L (ppb) 5. Response time: <2min (90%, 20 °C). 6. Polarization time: ≥1h. 7. Stability: Under normal pressure constant temperature, drift <2%F·S every month. 8, sensor (electrode) life: > 1 year. 9, water sample temperature: 0 ~ 45 ° C. 10. Minimum flow rate: 15 cm3 / s, (maintain constant flow rate). 11. Isolated output: 0~10mA (load resistance <1.5KΩ); or 4~20mA (load resistance <750Ω) or 485 signal output. 12. Alarm relay normally open contact: 3A 240VAC, 6A 28VDC or 120VAC. 13, power supply: 85 ~ 265VAC 50 ± 1Hz. 14. Dimensions: electronic unit (transmitter): 150 (length) × 150 (width) × 235 (deep) mm; Mounting hole size: 91*91. 15, quality: 2.5Kg. 16, measuring pool installation: can be fixed on the wall or other means. The lower part of the measuring cell is the water inlet, The upper part is the water outlet and is equipped with a pipe joint, which is connected with a Φ10 stainless steel hard pipe or hose. 17. Electrode installation: residual chlorine, pH electrode and temperature electrode are loaded into the measuring cell. 18. The length of the connecting cable between the electronic unit (transmitter) and the electrode inside the measuring cell is 3~5m. 19. Maintenance: Calibration every 1~2 months; replace the chlorine membrane and electrolyte every 3~6 months.
