Thermocouples IEC

Our IEC Thermocouples range offers a comprehensive selection of temperature sensors designed for accurate and reliable measurement across a wide variety of applications. The range includes mineral insulated thermocouples, fine wire exposed junction sensors, moulded-on thermocouples, and fabricated or specialist probes, all manufactured in accordance with IEC colour standards.

We provide sensors in multiple probe styles, diameters and configurations, including fast response probes, surface and magnet-mounted thermocouples, and assemblies with terminal heads or specialised mountings. A wide choice of cable types such as PFA, PTFE and glassfibre, along with various termination options including miniature plugs and bare wire tails, ensures flexibility for different installation and environmental requirements.

In addition, the range includes application-specific solutions such as surface probes, bolt-on and pipe sensors, air and needle probes, and heavy-duty industrial thermocouples, making it suitable for use in industries including manufacturing, HVAC, process control and laboratory testing. Overall, Labfacility’s IEC thermocouples provide a versatile and dependable solution for both general-purpose and specialist temperature measurement needs.

Long term Stability	Variable, Prone to ageing	Excellent	Good
Temperature range	-200 to1750°C	-200 to 650°C	-100 to 300°C
Thermal response	Sheathed – slow Exposed tip – fast 0.1 to 10 secs typical	Wirewound – slow Film – faster 1-50 secs typical	generally fast 0.05 to 2.5 secs typical
Excitation	None	Constant current required	None
Characteristic	Thermovoltage	PTC resistance	NTC resistance (some are PTC)
