Manufacturer : TECHNO MORIOKA
Model: 7737-A100

The industry’s thinnest, most compact electrical resistivity meter (resistivity meter)

confirmation; dc power supply; DIN rail mounting; No water quality information provided; Analog output

This is an ultra-thin electrical resistivity (resistivity) measurement module.
With a width of just 26mm, it’s one of the thinnest electrical resistivity (resistivity) measurement modules in the industry, allowing for space-saving installation in control panels and other applications.
It features analog output (4-20mA) and can output two parameters: water quality and water temperature.
The use of a plug-in terminal block reduces installation time.
Please use it in combination with the 7770 sensor series.
