TRUST IN EVERY DEGREE:
45 YEARS OF THERMOCOUPLE CALIBRATION EXCELLENCE
For 45 years, Isotech has stood at the forefront of temperature calibration. As we mark this milestone, our mission remains unchanged: to provide engineers and laboratories with the equipment and support they need for successful temperature calibration.
Thermocouples remain the most widely used temperature sensors; they can be cost-effective and can be used at high temperatures. Yet, to realise their full potential— especially in demanding industrial or laboratory settings— precise calibration is essential. This is where Isotech offers a distinct advantage: not only do we design and manufacture a complete range of thermocouple calibration equipment, we also operate one of the most respected ISO 17025 accredited laboratories in the world.
The Widest Selection of Thermocouple Calibration Solutions
Our calibration solutions are trusted globally— from national metrology institutes to field technicians. Isotech offers a complete system for thermocouple calibration, including:
Fast Response Dry Blocks
Dry block calibrators are ideal for thermocouple calibration, offering a wide temperature range from-45 ° C to 1200 ° C. Their compact design suits both laboratory and field use. Precision inserts ensure good thermal contact and immersion depth for accurate comparison calibrations. When used with a reliable reference thermometer, they provide fast, accurate, and traceable results. High-Performance Calibration Furnaces The new Model 547 Thermocouple Calibration Furnace delivers exceptional stability(± 0.08 ° C) across a wide range from 150 ° C to 1200 ° C. Designed for flexibility, it can be used vertically or horizontally- including passthrough calibration of multizone thermocouples. With programmable automation and fast cool-down via Dynamic Heat Flow Technology, the 547 is an ideal solution for calibration professionals.
Low Uncertainty Standard Thermocouples Our range of standard thermocouples, including Platinum / Platinum Rhodium, Platinum / Palladium, and Gold / Platinum types, supports uncertainties as low as ± 0.2 ° C to ± 0.55 ° C across the range from 0 ° C to 1330 ° C. The Homogeneity Challenge— Solved The Model 881 Homogeneity Scanner offers a fully automated solution for evaluating thermocouple uniformity. Inhomogeneities in thermocouple wires can cause significant calibration errors. The 881 allows laboratories to identify problematic regions, determine annealing needs, and assess uncertainty due to inhomogeneities. Thermocouple Reference Junction Units To ensure traceability throughout the calibration chain, Isotech supplies precision cold junction units to suit everything from a laboratory to a nuclear power station.
Measuring Equipment and Automation Software
From single-channel to multi-channel high-accuracy thermocouple measuring systems, these options enable full thermocouple characterisation— calculating coefficients, performing multi-point calibration, and producing certificates with ease.
More Than Equipment— A Trusted Partner
What sets Isotech apart is not only the quality of our instruments, but also our experience. As both a manufacturer and operator of a UKAS-accredited calibration laboratory, we understand the challenges faced by metrologists, technicians, and engineers. Our team brings real-world calibration experience into every product we design.
Whether you’ re establishing a new laboratory, upgrading your thermocouple standards, or looking to improve turnaround times and reduce uncertainty, Isotech can help. Our 45 years of experience are at your service.
