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 that is installed in water areas where wired connections are difficult, such as dams, lakes, and coastal waters, and automatically measures water temperature over a long period of time. The water temperature detection unit is suspended from a float and powered by dry batteries, and data transmission is sent to the land wirelessly, eliminating the need for communication and power cables, making it easy to moor to existing facilities. By installing multiple water temperature detection units, measurements at different depths are also possible. 【Features】 ■ Precise measurement using a thermistor ■ Surface tracking by float suspension ■ Detection unit powered by dry batteries ■ No cable installation required due to wireless transmission ■ Can be moored to existing float platforms or net areas *For more details, please download the PDF or feel free to contact us.

Company information
For over 50 years, we have been involved in the development and manufacturing of hydrological, water quality, and oceanographic observation instruments that are committed to field specifications in order to understand water as it is. 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 if it were flowing freely, into a limited resource. They have realized that this has placed excessive burdens not only on themselves but on all living beings, that is, the natural environment. Now, there is a significant shift in awareness regarding the importance of water resources. To create an environment where people can appreciate nature, the DENTAN Group will continue to do our utmost, albeit with limited power.
