Online Residual Chlorine Meter
The Online Residual Chlorine Meter is designed for continuous residual chlorine monitoring in water treatment, drinking water distribution, swimming pools and cooling circulating water systems. This residual chlorine analyzer provides stable chlorine measurement for online water quality monitoring and helps users improve disinfection control, dosing accuracy and water safety management.
- Product Introduction
Measurement principle
The CLB-H4130 online residual chlorine meter uses a single microprocessor to measure active chlorine, pH, temperature and residual chlorine conversion.
Technical parameter
|
Measuring range |
Residual chlorine: 0~10.00mg/L (maximum 20mg/L), resolution: 0.001mg/L; Temperature: 0~45℃, resolution: 0.1℃; PH: 0~14PH (if the PH value of water quality is stable, it can be left out when measuring with PH electrode). |

Functional description
- Intelligent: a single chip microprocessor is used to complete the measurement of residual chlorine value, pH value and temperature;
- Human-computer dialogue interface: menu operation structure, users can operate according to the prompts on the screen;
- Network: can be transmitted, monitored and controlled remotely;
- Isolated output current: software selects 0~10mA or 4~20mA output;
- Measurement range: the upper limit and lower limit parameters correspond to the output current can be set freely;
- Upper and lower limit alarm can be set arbitrarily, and the limit will flash (measurement status);
- Two sets of relays control, with adjustable hysteresis, allowing external connection to metering pumps, solenoid valves, and other control devices for automatic dosing and other controls;Set your own password, users can set or change their passwords to prevent unauthorized personnel from entering and causing incorrect operations; it also helps you recover forgotten instrument passwords; and provides contact methods for technical consultation and after-sales service;
- Zero point calibration, slope calibration and two-point calibration of pH electrode with residual chlorine electrode; measurement error correction function;
- RS485/RS232 communication can be provided according to the user's order statement.
