Hand Held Thermocouple Probes (Type 5)

What is a Thermocouple Probe?

A thermocouple probe is a sensor used to measure temperature by utilsing the principle of thermoelectricity. It consists of two different metal wires welded together at one end - the hot junction. When this junction encounters a temperature change, it generates a voltage, allowing for precise temperature measurement. Find out more about how a thermocouple works

The Purpose of Handheld Thermocouple Probes

Handheld thermocouples are designed for easy measurement of on-site temperatures. They consist of a handle for easy gripping, a probe sheath to protect the thermocouple wires, and a junction (sensor) at the tip for temperature detection. They usually have a miniature thermocouple connector fitted at the end of a flexible cable for quick connection to hand held instruments.

Ideal for applications requiring on-site measurements and temperature checks, these portable probes find applications across various industries:

• Food Industry: Handheld thermocouples are used extensively in kitchens and food processing areas to ensure food safety and maintain optimal cooking temperatures.
• HVAC and Refrigeration: Technicians rely on them to diagnose issues and regulate temperatures in heating, ventilation, air conditioning, and refrigeration systems.
• Laboratory and Scientific Research: These probes play a pivotal role in scientific experiments where precise temperature measuring is required.
• Industrial Applications: From manufacturing processes to quality control, handheld thermocouples are essential in ensuring optimal operating temperatures for machinery and processes.

Handheld thermocouple probes come in various styles, each catering to specific applications and environments. Here are some common styles:

These have a straight, pointed tip for easy insertion into solid or semi-solid materials, ideal for checking internal temperatures of food or monitoring machinery.

Featuring a very fine, sharp point, they are used for delicate or small samples, such as in laboratory experiments (style GG). They are also availble in a robust style that allows them to be hammered in to hard surfaces like frozen food (style HH).

These have a flat sensor (ribbon) that makes direct contact with surfaces for temperature measurement, often used in industrial settings for monitoring machinery or flat surfaces.

These measure the temperature of air or gases, commonly used in HVAC systems, ovens, or environmental monitoring. They have a perforated tip to allow the air or gas to circulate around the sensing tip.

Submerged directly into liquids, these probes measure temperatures in solutions or liquids, vital in laboratory settings, brewing, or chemical processing.

These rugged semi-rigid sensors are well suited to general pupose applications. The mineral insulated construction enables them to be bent or twisted to achieve access in difficult to reach applications. They can be used for immersion in liquids or for air temperatures albeit with a slower response than a specific air/gas thermocouple.

Handheld thermocouple probes are used for diverse applications across industries, ensuring precise temperature measurement and control for safety, quality, and efficiency in various processes and environments.
