The Air and Gas Thermistor Probe with Handle – HI762A is designed to measure the temperature of air and gas samples. The response time of a measurement is affected by the position of the sensor relative to the surface being measured. The HI762A construction with vent holes located at the tip of the probe offers a 6-second response for a temperature reading. With a strong, corrosion-resistant, AISI 316 stainless steel construction, this probe is able to measure samples up to 150℃ (302℉).
