The "RC-50T Series" is a chlorine meter suitable for managing effective chlorine concentrations for deodorization, capable of handling low concentrations (0 mg/L) to high concentrations (approximately 12%). No calibration is required like other electrode methods, allowing for measurements to be taken in a short time. The operation is simple as it only requires the addition of a sample (50 μL). Additionally, it uses an electrochemical sensor that excels in linearity compared to colorimetric methods. 【Features】 ■ No calibration required like other electrode methods ■ Simple operation as it only requires the addition of a sample (50 μL) ■ Measurements can be taken in a short time ■ Excellent accuracy and reproducibility that is not affected by the operator's skill ■ Uses an electrochemical sensor that excels in linearity compared to colorimetric methods *For more details, please refer to the PDF document or feel free to contact us.

The "RC-1202W" is a high-concentration residual chlorine controller that is unaffected by chloride ions (Cl-) up to 30,000 mg/L, making it suitable for measuring residual chlorine concentrations in seawater. With panel operation from the front, various data settings can be easily configured, and the adoption of an automatic cleaning mechanism allows for stable measurements over long periods. Additionally, it is hardly affected by suspended substances in the sample. 【Features】 ■ Unaffected by chloride ions (Cl-) up to 30,000 mg/L ■ Can be used for measuring residual chlorine concentrations in seawater ■ Easy data setting through front panel operation ■ Stable measurements over long periods due to the automatic cleaning mechanism ■ Hardly affected by suspended substances in the sample *For more details, please refer to the PDF document or feel free to contact us.

The "MWB4-72 model" is a device that fully automates the daily water quality tests mandated by regulations, achieving enhanced water quality management and significant labor savings. By adopting dedicated software, it enables simultaneous centralized management of data information and allows for remote maintenance during abnormal conditions, including cleaning and zero calibration operations. The cleaning of the turbidity and color measurement cell section employs automatic cleaning through water flow, eliminating movable parts and significantly improving durability. 【Features】 ■ Remote monitoring system ■ Battery backup support ■ Excellent operability and maintainability ■ Continuous measurement of 7 items without reagents ■ Compact body *For more details, please refer to the PDF materials or feel free to contact us.

The CM-60 is a free residual chlorine/pH composite measurement device suitable for applications such as sterilization processes in food and beverage factories, and effluent from factories and sewage treatment plants. It automatically corrects the pH error of free residual chlorine using a pH sensor, allowing for stable measurements within a sample water pH range of 5 to 8.5. Additionally, the measurement method is the membrane polarographic method. 【Features】 ■ Easy maintenance due to the use of a membrane ■ No influence from combined chlorine, allowing for selective measurement of free residual chlorine (HOCl) ■ Simultaneous measurement of free residual chlorine and pH significantly reduces initial costs *For more details, please refer to the PDF materials or feel free to contact us.

The "CL17sc" is an intermittent continuous residual chlorine meter that employs the DPD reagent for spectrophotometric measurement. It is used for measuring residual chlorine in drinking water and cooling water. With low cost and low maintenance, it performs measurements at 2.5-minute intervals, ensuring speed and reliability. While there are some differences in the composition of the buffer solution compared to the DPD method specified in the drinking water testing method (as per the Ministry of Health, Labour and Welfare), it can achieve a high correlation with the measurement values based on the drinking water testing method. 【Features】 ■ No sensitivity reduction due to contamination, as it uses a colorimetric method with reagents ■ Sensitivity reduction is prevented by adjusting the light intensity of the colorimeter (basically once a day) ■ Good maintainability, allowing for unmanned operation for up to one month ■ Reagents can be easily prepared by simply dissolving powdered reagents ■ The tubes used within the instrument are packaged as a kit, making tube replacement easy *For more details, please refer to the PDF document or feel free to contact us.
