Real-time temperature monitoring you can trust

Thermocouples are a vital component in medical devices. The small temperature sensors are embedded in a wide range of devices to ensure patient safety and the effectiveness of therapies. Given the advances of smarter medical devices made for precision, thermocouples are becoming more important for the industry.

Medical-grade thermocouples are temperature measurement devices based on thermo-electric operations, composed of bifilar and multi-filar wires made from traditional thermocouple alloys.

Our high-quality medical-grade thermocouples are used for measuring temperatures during therapeutic procedures, such as ablation to treat atrial fibrillation as well as in medical equipment such as ventilators.

Collaborate with us from design to development and manufacturing of ultra-fine, high-quality wire for signal transmission and medical thermocouples, delivering accurate temperature measurement for the most demanding applications.
