Temperature Probes / Thermocouple Probe

A thermocouple probe can be used to measure temperatures in a wide range of applications, ranging from laboratory experiments to industrial processes. The temperature probe consists of two wires, each made from a different metal which are then welded together at one end to form a junction. When this junction is exposed to a temperature gradient, a voltage is generated and converted into a temperature reading.
This type of temperature probes is a popular option due to its durability, accuracy, and ability to measure a wide range of temperatures. They are commonly used in industrial settings as well as in labs for research and in pharmaceutical development.
