Thermocouple
Product Description
A Thermocouple is a temperature measurement device consisting of two dissimilar metal wires joined at one end, creating a junction where a voltage is generated in response to temperature changes. This voltage can be interpreted by a measuring instrument to determine temperature accurately. Thermocouples are widely used in laboratories, industrial processes, and scientific research due to their wide temperature range, durability, and rapid response time. They are essential for precise thermal monitoring and control in experiments involving heating, cooling, and thermal reactions.
