Introduction This sensor is a thin-film current principle chlorine sensor, which adopts a three-electrode measurement system. The PT1000 sensor automatically compensates for temperature, and is not affected by changes in flow rate and pressure during measurement. The maximum pressure resistance is 10 kg. This product is reagent-free and can be used continuously for at least 9 months without maintenance. It has the characteristics of high measurement accuracy, fast response time and low maintenance cost. Application: This product is widely used in city pipe water, drinking water, hydroponic water and other industries. Technical Parameters
