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.
