Continuous measurement without delay! A continuous UV meter (organic pollution monitor) that is easy to calibrate and maintain.
The "HWUV-222S/311D" is a continuous UV meter (organic pollution monitor) that utilizes the ultraviolet absorbance method. Since it is an optical measurement that does not require chemicals or heating, it can perform continuous measurements without delay, making maintenance of the device easy, and it has a high correlation with COD. The effects of turbidity and contamination of the measurement cell are eliminated, and the measurement cell is automatically cleaned with a reagent regularly, ensuring stable measurements. 【Features (excerpt)】 ■ Product that complies with the Ministry of Land, Infrastructure, Transport and Tourism's standard specifications for automatic ultraviolet absorbance measuring instruments (UV meters) ■ Adopts a single optical path dual-wavelength method, unaffected by changes in the temperature of the light source or over time ■ No reagents required, easy calibration and maintenance ■ Simple batch measurement possible with 1-2L of sample water ■ Sampling type (HWUV-222K) and immersion type (HWUV-311D) can be selected according to application * For more details, please refer to the PDF document or feel free to contact us.
