Starting from April 2022, a method using portable residual chlorine meters has been added to the "testing methods for free residual chlorine and combined residual chlorine established by the Minister of Health, Labour and Welfare." ↓↓↓ The use of portable residual chlorine meters has been officially recognized as a testing method for drinking water! - Compact handheld type that is easy to hold with one hand - Display section with backlight for visibility in dark places It is excellent for use in the field!

The "CD-2000" is an easy-to-use coulometric chlorine demand meter designed for research on chlorine consumption reactions. It allows for the quick and simple measurement of chlorine demand in raw water such as rivers, lakes, reservoirs, groundwater, and seawater using the coulometric method. It manages the chlorine injection amount for chlorine treatment appropriately at a low running cost. 【Features】 ■ Easy operation and low running cost for research on chlorine consumption reactions ■ Adopts a feed-forward method *For more details, please refer to the related links or feel free to contact us.

The water quality of the water source shows a trend of complex pollution, and there is a demand for advanced and strict chlorine treatment and management in water purification processes. The traditional feedback method, which seeks appropriate values after chlorine injection, has posed health and economic issues. Therefore, it is desirable to establish a feed-forward method that captures the chlorine demand of raw water in advance and processes it. From sampling to measurement, all substances in raw water, such as ammonia nitrogen, iron, manganese, and organic matter, will be continuously and fully automatically measured for their chlorine demand in a short time. It can be used as a monitor for surveillance and, in combination with chlorine injection equipment, for accurate chlorine injection control as an automatic proportional injection system. 【Features of the CD-12MF model】 - Improved rotating platinum electrode for residual chlorine detection - No pre-treatment by filtration required even for high turbidity samples - Continuous measurement of chlorine demand in raw water - Follows rapid changes in raw water quality - Expanded screen size for improved visibility - Easy operation via touch panel - Equipped with USB functionality
