Air and Gas Pt100 Probe - HI768L

The HI768L is an air and liquid 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 rounded tip of the probe allows users to obtain highly accurate temperature readings of air and liquid samples.

  • Measures up to 350℃ (622℉)
  • Pt100 sensor
  • AISI 316 stainless steel


The Air and Gas Pt100 Probe – HI768L is designed to measure the temperature of air and liquid 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 HI768L probe is able to measure samples up to 350℃ (622℉).
