By installing multiple water temperature detection units, it is also possible to measure at different water depths!
The "ETR-12 model" is a wireless transmission float-type water temperature monitoring device designed to be installed in water areas such as dams, lakes, and coastal regions where wired connections are difficult. It automatically measures water temperature over an extended period. The water temperature detection unit is suspended from the float and powered by dry batteries, with data transmission sent wirelessly to the land, eliminating the need for communication and power cables, and allowing for easy mooring to existing facilities. By installing multiple water temperature detection units, measurements at different depths can also be achieved. 【Features】 ■ Precise measurement using thermistors ■ Surface-following via float suspension ■ Detection unit powered by dry batteries ■ No cable installation required due to wireless transmission ■ Mooring to existing float platforms or net areas is also possible *For more details, please download the PDF 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.
