Lightweight, simple, and high-performance! The concepts are reproducibility, durability, and high precision.
The "FNW-522 model" is an easy-to-install turbidity monitoring device. The light beam emitted for turbidity measurement has a large diameter of 17mm. Therefore, even if slightly larger particles of debris mix into the water being measured, it does not significantly affect the turbidity value. Additionally, the sensors used in this product condense the field knowledge gained over a long period since the installation of the first unit into a lightweight and compact form. 【Features】 ■ Transmission scattering light method with minimal influence from particle size and color ■ Light beam monitoring function that self-controls the light output of the light source ■ Waterproof technology that allows the wiper to operate even at a water depth of 300m ■ Wiper cleaning mechanism that "prevents dirt" rather than "removes dirt" ■ Accuracy of ±2 degrees in normal river turbidity ranges *For more details, please refer to the PDF materials or feel free to contact us.

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.
