The Sensor Scientific Raw Sensor enables accurate temperature measuring from remote locations. The thermistor assembly features vinyl housing with dimensions 0.20” dia x 1” and eight feet long PVC zipcord lead. The sensor operating range is from -10°C to +70°C (+14°F to +160°F). RTD ( Resistance Temperature Detector) with resistance values 100, 500, 1,000, & 2,000 Ohms at 0°C is also available as a temperature measuring element.
