The Penetration K-Type Thermocouple Probe – HI766PC is designed to measure the temperature of semi-solids and high-temperature samples. The response time of a measurement is affected by the position of the sensor relative to the surface being measured. The HI766PC pointed tip construction offers a 15-second response for a temperature reading. With a strong, corrosion-resistant, stainless steel construction, this probe is able to measure surfaces up to 900℃ (1650℉).
