Wide-Range
Temperature
(Order Code GDX-WRT)
This rugged temperature probe features a wide temperature range, from –20°C to
330°C. The high upper limit of the sensor allows for melting point
determinations of most organic compounds. It uses platinum RTD (Resistance
Temperature Detector) technology to establish a ±0.5°C accuracy or better, as
well as excellent stability and repeatability. Each unit is individually calibrated,
and the calibration is stored on 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.
