Intelligent Online Free Chlorine Analyzer with CS4 Sensor for Tap Water
Published on by Susan Su for Dabeco
The Online Residual Chlorine Analyzer is equipped with German-made CS4 sensor, its detection part adopts special osmotic membrane technology, resisting chemical interference (mainly from surfactants) and reducing pH dependence. The sensor is unaffected by water quality, with fast response, stable performance, low cost, minimal maintenance, and provides reliable, accurate data. The instrument with a LCD screen displays disinfectant value (main), aqueous solution pH (requires optional pH electrode), and working status, outputting analog, digital, and switching signals. This analyzer applied to tap water, swimming pool water, medical wastewater, sewage water treatment, fruit and vegetable disinfection; seawater, high-salt seawater, pipeline disinfection, industrial water treatment fields etc.
Application Fields
Tap water: 0 - 2mg/L;
Swimming pool water: 0 - 5mg/L for the measurement of cyanuric acid;
Medical water: 0 - 0.5mg/L; with a conductivity as low as 10μS/cm;
Sewage treatment: 0 - 20mg/L;
Fruit and vegetable disinfection: 0 - 200mg/L;
Seawater: with a conductivity as high as 50mS/cm;
High - salt seawater: brine or seawater with a concentration greater than 3.5% (>50mS), and the salt content can be up to approximately 26%;
Pipeline disinfection: 0 - 2.5mg/L with a water temperature as high as 70℃;
Industrial water treatment: 0 - 2000mg/L, etc.
Functional Features
Standard - equipped with imported sensors, ensuring accurate measurement and stable performance.
One-key calibration, historical data recording and export.
Standard MODBUS RTU communication protocol.
Dual high-impedance pre-amplifiers: High input impedance, noise-proof, and strong anti-interference ability.
Stable zero-point. Only one-point calibration is required on-site, and multiple calibration methods are also provided.
Human-machine interaction: Menu-based operation structure, allowing users to operate following the on-screen prompts.
Multi - parameter display on the same screen: Simultaneously display the main measured value, pH value (optional), current output, and working status.
Two-way output signals: The software can select from three output modes: 4 - 20mA / 20 - 4mA / 0 - 20mA.
Free setting of the measurement range and alarm upper and lower limits; High and low limit over-range alarm prompts.
Three sets of relay control switches with an adjustable hysteresis control range.
Self - set password: Users can set or modify passwords to avoid misoperation.
