Non-Reversible Temperature Labels

These labels feature specialized indicators that undergo a permanent color change once a specific temperature threshold is reached. Unlike reversible displays, this change is tamper-proof and remains visible even after the temperature drops, providing an indelible physical record that a limit was exceeded.

The 4-point design is ideal for monitoring equipment health, product shipping, and laboratory quality assurance. By covering a range of four distinct temperatures, they help technicians identify not just if a failure occurred, but the specific thermal bracket reached during operation or transit.

The non-reversible labels provided by HK Calibrations are engineered for precision, typically offering an accuracy of ±1°C of the required rating. This high level of reliability is essential for industries like aeronautics, HVAC, and electrical maintenance where minor temperature fluctuations can indicate significant mechanical stress.

Yes, they are designed with a strong adhesive backing that allows them to be easily applied to a wide variety of surfaces, including metal housings, plastic packaging, and electrical components. Their low profile ensures they can be used in tight spaces where traditional bulky sensors might not fit.

The collection covers an extensive range of thermal requirements, with specific models ranging from as low as 40°C (105°F) up to 260°C (500°F). This versatility allows users to select the exact label needed for everything from sensitive electronics to high-heat industrial machinery.

The immediate visual feedback allows for rapid "go/no-go" inspections without the need for specialized electronic reading equipment. This streamlines quality control processes in warehouses and factories, ensuring that any item exposed to out-of-spec temperatures is identified and quarantined instantly.
