The HI768A is an air and gas Pt100 probe designed for use with one of Hanna’s Pt100 thermometers. A cable extends 1 m (3.3’) from the handle to the meter connection. The vent holes at the tip of the probe allow users to obtain highly accurate temperature readings of air and gases.
The Air and Gas Pt100 Probe - HI768A is designed to measure the temperature of air and gas samples.
The operating principle of resistance thermometers is based on the increase of electric resistance of metal conductors (RTD: Resistance Temperature Detectors) with temperature. Among the various metals to be used in the construction of RTDs, platinum (Pt), a noble metal, is one that can measure temperatures throughout a wide range with a stable, linear behavior. The most common RTD sensor using platinum is the Pt100. Hanna’s Pt100 thermometers and probes use multi-wire technology in the connection cable to obtain high levels of accuracy in industrial and laboratory applications.
With a strong, corrosion-resistant, AISI 316 stainless steel construction, the HI768A probe is able to measure samples up to 350°C (622°F).
