Accurate online residual chlorine analyzer

strive forAccurate online residual chlorine analyzerFCl-2058 adopts a film covered constant potential method with a 3-electrode system, which hasTechnological advantages and wide industry applications. The electrode has achieved automatic temperature compensation internally, ensuring high accuracy and stability of measurement results. The special membrane structure enables it to resist surfactants, has excellent mechanical strength, and is not easily damaged. In repeated tests at pH 7.2 and 25 ° C, the accuracy is less than 1% within the range of less than 2ppm. The zero point of the electrode is stable and does not drift, with a slope drift of about -1% per month. In addition, the FCl-2058 electrode adopts the standard Modbus RTU (485) communication protocol, DC 24V power supply, and four wire mode, which can be easily connected to the sensor network.
