Intelligent Online Total Chlorine Analyzer with CP4.0 Sensor for Medical Wastewater

The Online Total Chlorine Analyzer is equipped with a German-made CP4.0 sensor, adopting special osmotic membrane technology. It resists chemical interference (mainly surfactants), reduces pH dependence, and is not restricted by water quality. With fast response, stable performance, low cost, and minimal maintenance, it provides users with reliable and accurate data.

Featuring an LCD screen, the instrument can automatically identify measured parameters. It has current 4-20mA and RS485 output, allows free setting of the measurement range, provides high and low limit alarm prompts, The electrode supports multiple automatic calibration methods. Widely applied in measuring tap water; swimming pool water ; medical wastewater; sewage treatment ; seawater; high-salt seawater etc.

Working Principle:

The entire measurement system mainly consists of two parts: the instrument and the sensor. The instrument displays the disinfectant value (main measured value), the pH value of the aqueous solution (a pH electrode is required for selection), and the working status. It outputs signals such as analog, digital, and switching signals.

The sensor is from the original German - imported RG brand and operates based on the principle of the constant - current method of the film - covered three (dual) electrodes. It has the characteristics of anti-interference and anti-pollution.

 

Application Fields:

Functional Features

  1. Standard - equipped with imported sensors, ensuring accurate measurement and stable performance.

  2. One-key calibration, historical data recording and export.

  3. Standard MODBUS RTU communication protocol.

  4. Dual high-impedance pre-amplifiers: High input impedance, noise-proof, and strong anti-interference ability.

  5. Stable zero-point. Only one-point calibration is required on-site, and multiple calibration methods are also provided.

  6. Human-machine interaction: Menu-based operation structure, allowing users to operate following on-screen prompts.

  7. Multi - parameter display on the same screen: Simultaneously display the main measured value, pH value (optional), current output, and working status.

  8. Two-way output signals: The software can select from three output modes: 4 - 20mA / 20 - 4mA / 0 - 20mA.

  9. Free setting of the measurement range and alarm upper and lower limits; High and low limit over-range alarm prompts.

  10. Three sets of relay control switches with an adjustable hysteresis control range.

  11. Self - set password: Users can set or modify passwords to avoid misoperation.
