PT100 Temperature Sensor


The best RDT PT100 temperature probe available today. Temperature range of -200℃ to 400℃.

RTD PT100 Temperature Sensor Description:

UbiBot’s RTD PT100 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 reflects the actual measured temperature.

A fiberglass shields the probe’s lead wire so that the wire can withstand temperatures of up to 200℃ . The PT100 RTD sensor uses a chip imported from Germany, which has high stability and uses a 3-wire connection mode to ensure the accuracy and anti-interference ability.
