PT100 Industrial Grade Temperature Probe


PT100 high-precision industrial temperature probe with a range of -200℃ to 400℃.


Industrial Temperature Sensor:

PT-100 industrial temperature sensor designed for applications between -200℃ and +400℃. A specially treated platinum wire forms the inner surface of the PT-100 probe. This design quickly and accurately reflect the actual measured temperature.

A fiberglass shields the probe’s lead wire so that the wire can withstand temperatures of up to 200 degrees Celsius. PT-100 uses a chip imported from Germany which is high stability and uses a three-wire connection mode to ensure the accuracy and anti-interference ability.
