Introduction: The DRCLD-98 colorimetric method online chlorine dioxide analyzer uses the DPD colorimetric method to detect the concentration of chlorine dioxide. It is a precise, cost-effective and low-maintenance instrument suitable for chlorine dioxide measurement during chlorination And monitoring of chlorine dioxide concentration in drinking water pipe networks. The reagent consumption for 30 days of continuous operation enables unattended operation and low operation and maintenance costs. Suitable for chlorine dioxide measurement of tap water, circulating cooling water, sewage and other chlorination and disinfection processes, and chlorine dioxide measurement of tap water pipe network, integrated structure, easy to install Features: 1. The DPD standard colorimetric method has good accuracy and stability. 2. Use built-in curve calibration 3. Automatic turbidity and automatic chromaticity compensation; 4. It is not affected by PH value and can mask the interference caused by other oxidants. 5. Small-capacity flow cell, less reagent consumption, no need to replace reagents within 30 days of continuous operation, simple operation, low operation and maintenance costs; 6. With automatic cleaning function, reduce maintenance; 7. With reagent remaining alarm function; 8. Measurement mode: continuous measurement mode, periodic measurement mode (measurement period is adjustable) Measuring principle Add a pH buffer reagent to the water sample and adjust the pH value of the sample to a certain range. The chlorine dioxide in the sample will oxidize the DPD (N,N-diethyl-1,4-phenylenediamine) indicator to For red compounds, the intensity of the color is directly proportional to the chlorine dioxide content in the sample. Measure the absorbance of the color sample with a 560nm light source, and then compare the absorbance with the sample without any reagents to calculate the chlorine dioxide value in the water sample. Technical Parameters: Measuring range: 0~5ppm chlorine dioxide Accuracy: ±5% of reading or ±0.03ppm as Cl2, whichever is greater Detection limit: 0.03mg/L Sample flow rate: 200-400mL/min Sample inlet pressure: 0.1~5bar Sample temperature: 5~40℃ Analog output: 4-20mA, loop load 500Ω. Digital output: RS485 MODBUS communication protocol Control output: 2 alarm relays Display screen: 70mm×48 mm LCD display Ambient temperature: -10-55℃ Relative humidity: 5%-90%, no condensation Protection level: IP65 Power supply: 220VAC 50HZ 20W standard Installation method: wall-mounted installation Dimensions: 350mm*186mm*460mm (length * width * height) Weight: about 9kg
