basic information
■Usage Precautions ● When using for the first time, please be sure to perform calibration. This product comes with the following sample sets necessary for calibration: - For CL calibration: DPD reagent simple set for 10 uses (M85EW-520T/521T) - For pH calibration: Powder for pH standard solution, 3 types of pH for 1 use (M85EW-521T) *For subsequent calibrations, please prepare commercially available DPD reagent-type residual chlorine meters or pH standard solutions. ● The residual chlorine meter and pH meter need to be cleaned and calibrated after one week from the last calibration or after every 50 measurements. ● Do not use the residual chlorine meter for purposes other than residual chlorine measurement and the functions provided. ● Do not damage the electrode part of the sensor. It may prevent accurate readings. ● When measuring water with many impurities, such as in pools or baths, please clean the sensor each time you measure. Impurities may adhere to the sensor and cause deterioration. Additionally, calibration is required once a day. ● Do not immerse the residual chlorine sensor in cold springs, hot springs, mineral water, well water, alkaline ion water with chlorine concentrations of 3 mg/L or higher, or in weakly acidic or strongly alkaline water. This may cause malfunction.
