KTW Thermistor & RTD Sensor

Brand: Kele

The Kele KTW Immersion Sensors are designed to be cost-effective with accuracies of ±0.28° C (±0.5° F). 

Each sensor is constructed for easy installation with any building automation system (BAS). 

The thermistor is made of a very stable, pre-aged material that offers long-life reliability for HVac control. 

The platinum RTD comes in 100 Ohms and 1000 Ohms versions. All sensors come with a three-year warranty.
