TECHMO 7701 Series Sensor

Manufacturer : TECHNO MORIOKA
Model: 7701 series

It offers excellent responsiveness to heat, enabling accurate measurements even in environments with drastic temperature changes.

Mounting diameter R1/2; Installation piping R3/4; Electrode part: Titanium

These are sensors (measuring components) for the 7731/32, 7721/22, and 7741/7742/7735 series.
The cables are connector-connected for easy installation.
You can select the appropriate sensor based on the material (metal/plastic) and thread diameter (R3/4/R1/2) of the piping you will be installing it on.
A separate sensor cable is required.
Please refer to the page for the dedicated cable for the 7701 sensor.

Compatible sensors

Compatible water quality meters: 7721, 7722, 7731, 7732. 7735, 7741, 7742
