Adopting the twin spectrum method.
This product enables continuous monitoring of COD values through UV (ultraviolet absorbance) measurement. Its high water pressure resistance and compact design allow for direct measurements at great depths, achieving high-precision vertical distribution observations. It employs a twin-spectral method to simultaneously detect ultraviolet and visible light absorbance, correcting for the influence of suspended substances as much as possible. Measurement errors are fully compensated by constantly monitoring changes in light intensity, ensuring accurate measurements at all times.

Company information
To understand water as it is, we have been involved in the development and manufacturing of hydrological, water quality, and oceanographic observation instruments with a focus on field specifications for over 50 years... The DENTAN Group has served as a bridge between people and nature, watching over outdoor water environments. During this time, people have transformed water, which was once abundant and used metaphorically in Japan as flowing like water, into a limited resource. They have realized that this has placed excessive burdens not only on themselves but also on all living organisms, that is, the natural environment, and now they are significantly reassessing the importance of water resources. To create an environment where people can enjoy nature, the DENTAN Group will continue to do its utmost, albeit with limited power.
