This rugged temperature probe features a wide temperature range, from –20 to 330°C. The high upper limit of the sensor allows for melting point determinations of most organic compounds.


Vernier’s wide-range temperature probe uses RTD (Resistance Temperature Detection) technology to establish a ±0.1°C accuracy, as well as excellent stability and repeatability. Each unit is individually calibrated, and the calibration is stored on a smart chip in the sensor. It is designed to be used as you would use a thermometer for experiments in organic and inorganic chemistry, physics, biology, Earth science, and environmental science.


  • Temperature range: –20 to 330°C (–4 to 626°F)
  • Maximum temperature that the sensor can tolerate without damage: 380°C
  • Resolution: 0.10°C
