Hafsel fixed

The fixed reference electrode is designed for use in soil and fresh water (up to 500ppm chloride), which is buried near the structure to monitor the voltage level during cathodic protection.

4-terminal band box

Bandbox characters: made based on IPS-D-TP-704 and IPS-D-TP-702 standard maps.

shunt resistance

Achieving high accuracy in measurement should be done very carefully during manufacturing of manganin and finally, each piece should be calibrated separately.

Silica gel chamber

The transformer dehumidifier includes a container that is filled with silica gel dehumidifier grains injected by means of cobalt crystals.
