IP68 Waterproof Thermistor Sensors

Our IP68 rated NTC thermistor sensors have been designed to ensure moisture and water ingress will not cause temperature measurement problems.

The sensing element is moulded in TPE which is then over-moulded to single or double insulated TPE cable; this helps to ensure IP68 integrity.

Numerous R25 resistance values available, just call us to discuss your NTC thermistor sensor requirements.
