LinkMejor 5mm x 10mm PT100 Type Temperature Sensor Earth Thermocouple Probe 1M

A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either end of the pair of conductors.Grounded type is more sensitive to temperature, can help to measure temperature fasterly.5 x 100mm sensor PT100 type Thermocouple with flexible spring built in.2 terminals for easy connection. Temperature measurement range is from 0 celsius to 400 celsius degree.Widely used for industrial or laboratory to test equipments temperature.
