uxcell Detection Infrared Ray Photoelectric Switch NO AC 90-250V 300 mA 10 cm

Features with 2.7Meters long, 6mm thread diameter, 5 mm probe Length thermocouple. 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 fast. 2 terminals for easy connection. Temperature measurement range is from 0 Celsius to 400 Celsius degree. Widely used for industrial or laboratory to Test equipment's temperature.
