We offer a wide range of hand held surface thermocouple probes to suit a variety of surface temperature measurement applications. Depending on the thermocouple type, these probes can be supplied with a 1, 2, 5 or 10 metre (extended) coiled lead and a miniature flat pin plug which makes them suitable for all our hand held indicators as well as most other brands of indicators. They can also be connected to other instrumentation by using extension cable and the appropriate connectors.
Style | Description | Tip Image |
---|---|---|
BB | Spring Loaded Surface ProbeThis sensor has a ribbon style butt welded sensing tip which allows a fast response when placed upon a solid surface.The tip is rated to 400°C and the handle to 135°C. Sheath: 6.35mm dia x 165mm long (from handle to tip) |

Frequently Asked Questions
- What is a thermocouple and how does it work?
A thermocouple is a type of temperature sensor that generates a voltage when two different metals are joined at one end and exposed to a temperature difference between the "hot" junction (where the temperature is measured) and the "cold" junction (the reference point). This voltage is then measured to determine the temperature at the hot junction. - How do I choose the right thermocouple for my application?
The ideal thermocouple depends on factors such as temperature range, accuracy, termination type, mounting requirements and environmental conditions. We offer a variety of thermocouples with different sheath materials, constructions, terminations, and temperature ratings to meet your needs. If you need specific advice, our engineers are happy to assist! - What is the maximum temperature rating of your thermocouples?
Our thermocouples are designed to handle a wide range of temperatures with some mineral insulated thermocouples able to withstand temperatures up to 1400ºC and ceramic sheathed thermocouples going even higher to 1600ºC. Each product listing includes the maximum temperature rating, so you can choose the best thermocouple for your application.
