Residual Chlorine Analyzer

Product Details

Water quality is a global concern that affects the health of our entire ecosystem. That's why municipalities across the globe rely on HF scientific water measurement tools, water testing equipment, and chemical reagents to provide clean, safe water to the public.    The analyzer continuously detects the online residual chlorine concentration in water and uses the authoritative and reliable DPD colorimetric method. By automatically adding buffer reagent, the sample is adjusted to a certain pH range and the DPD becomes purple with the concentration of residual chlorine. The color depth depends on the chlorine content of the water sample.    Measurement parameters:  ● Chlorine    Application:  ● Tap water  ● Drinking water pipe network  ● Disinfection process  ● Reverse osmosis  ● Cooling water  ● Pool    Features  DPD colorimetric method, the measurement is more accurate and stable  - See American Standard Methods  - GB method, consistent with the laboratory method    Automatic diagnosis and automatic calibration  - Automated continuous self-diagnosis monitoring  - Built-in calibration curve, calibration is very simple    low reagent consumption, easy to replace  - Each reagent can measure 4000 times  - Reagent replacement is simple, simply pour the DPD powder into the indicator solution and dissolve it for use    Automatic and manual measurement mode  - Automatic measurement cycle optional: 300-3600s  - A key (down arrow) to quickly start a measurement    IP65 degree of protection  Indoor wall installation    RS485 output:  Standard Modbus RTU communication protocol. The baud rate is fixed at 9600.    Password protection to prevent unauthorized operations:  Password: 0022, English and Chinese menu    Features Measuring principle: DPD colorimetric method  Measuring range: 0 - 5.00mg / L (ppm) Residual chlorine  Resolution: 0.01mg / L  Accuracy: ± 1% f.s.  Measurement period: Can be set: 300 - 3600s (the instrument defaults to 300s)  Display: Multi-line LCD display (measured value, measurement mode and relay status)  Language: Chinese / English  Power: 90 - 260VAC, 50 / 60Hz  Analog Output: Isolated 4-20mA Output, Max.600?  Digital output: RS485 Modbus RTU  Alarm output: 2 sets of independent set Hi / Lo alarm points, with hysteresis setting, 5A / 250VAC  Operating conditions: Operating temperature: 0 - 50 ℃  Humidity: 10 - 95%, non-condensing  Influent flow: about 1L / min  Water pressure: about 1bar  Instrument Interface: Water Sample Import: φ10mm hose  Water samples export: φ10mm hose  Waste outlet: φ10mm hose  Protection class: IP65  Installation: Wall-mounted  Size: 450 x 350 x 200mm  Weight: ca. 5Kg
