JM provides accurate and reliable platinum thermocouple wire for temperature measurement applications. We consistently supply high quality wire and invest in research and development to provide greater value. We offer Type R, Type S and Type B platinum thermocouple wire in many diameters, as well as other special alloys or coatings. Our high purity, specially calibrated platinum wire is ideal for measurement of high temperatures by voltage generated at the junction of two dissimilar metals. And for particularly harsh environments, we’ve developed HTXTM platinum thermocouple wire - its exceptional strength provides reliable measurements in demanding applications.

You can now order through our express delivery service, getting your thermocouple wire shipped within 72 hours of order acceptance.

All thermocouple wire is calibrated to special limits or standard grade in our accredited calibration laboratory, in line with international standards.

Our Mineral Insulated Metal Sheathed (MIMS) thermocouples provide faster response to temperature change and are resistant to chemical and atmospheric environments. They are available in continuous lengths up to 18 meters. We also provide fine diameter calibrated wire for Resistance Temperature Detectors (RTDs), allowing fast and accurate measurement of high temperatures. Platinum RTD wire provides long term and stable measurements, the largest temperature range, and a stable resistance against the temperature profile.

Thermocouple temperature sensors with our precious metal wire provide strong resistance to corrosion, guaranteeing long service life and reliable measurement accuracy. Platinum and platinum-rhodium thermocouple wires are the ideal technology for measuring high temperatures up to 1850°C, while being able to withstand corrosive environments common in the glass, steel, oil and gas, and semiconductor industries. Our platinum thermocouple wire is used to measure temperature in:

Following our advice for storing your wire correctly will ensure its optimum performance. This will prevent any problems when using it, such as poor performance and breakages when using or removing the wire from the reel. The following tips will minimise any potential problems:
