Surface Thermocouple: Non-Invasive Precision for Solid Surface Temperature Measurement
The product is a specialized temperature sensor designed exclusively for solid surface monitoring, boasting a compact structure and exceptional adhesion to capture temperature changes rapidly. Unlike traditional thermocouples that require insertion, the Surface thermocouple attaches directly to objects, enabling non-destructive measurement without damaging the tested surface. Whether for industrial equipment maintenance, mold processing, or scientific research, the product delivers reliable performance across a wide range (-200℃~1200℃), making it an essential tool for scenarios where surface temperature tracking is critical. Its ability to adapt to various surface shapes-from flat to curved-further enhances its versatility in diverse applications.

Premium Materials & Reliable Accuracy of Surface Thermocouple
Every product is crafted with high-quality materials to ensure adhesion and durability. Its thermoelectrodes vary by type: cost-effective K-type (NiCr-NiSi) and E-type (NiCr-CuNi) for medium-low temperatures, and high-precision S-type (PtRh10-Pt) for high-temperature surface monitoring (0~1200℃).
Insulation and protection materials are tailored to each variant: polyimide film for patch-type (withstands 200~300℃), 304/316 stainless steel armored tubes for armored-type (wear and corrosion-resistant), and high-temperature permanent magnets for magnetic-type. Attachment aids like high-temperature adhesives and threaded connectors ensure tight contact with the tested surface.
Following national standards, the Surface thermocouple offers Class Ⅰ and Ⅱ accuracy, with errors dependent on fit tightness:
|
