Testo Temperature Sensitive Label 204 °C to 260 °C 2 Levels 0646 3341

Testo 0646 3341 Temperature Sensitive Label 2 Levels 204 °C to 260 °C is a high-precision heat monitoring solution designed to provide permanent visual indication of temperature exposure in industrial and commercial environments. This product features a self-adhesive foil label that adheres firmly to various substrates, including curved surfaces such as pipework. Its compact size (50 mm length by 18 mm width) allows it to fit into narrow or difficult-to-reach locations where traditional thermometers or sensors cannot be easily placed.

The dual-level temperature sensitivity of the label covers a range from +204 °C to +260 °C, with an irreversible colour change from light grey or yellow to black on reaching these heat thresholds within 1 second. This quick reaction time ensures prompt detection and allows operators to monitor heat exposure effectively, even after the object has cooled. Each pack contains 10 labels oriented vertically for ease of reading and practical application.

These temperature-sensitive labels are particularly suited for use in transportation industry applications, food processing plants, automotive and aerospace manufacturing, and electrical engineering tasks. They offer a reliable and cost-effective solution for measuring temperature levels on small components, moving parts, or hard-to-access spots where standard devices may fail.

Testo labels’ film construction provides flexibility and durability, making them resistant to harsh environments and mechanical stress. Their permanent colour change ensures clear and consistent heat level documentation for quality control and safety compliance in industrial processes. The absence of reversibility ensures no ambiguity in post-exposure inspection.

Supplied in packs of 10, these labels provide a convenient bulk option for maintenance teams and inspectors requiring consistent temperature monitoring across multiple assets. They align well with applications requiring temperature control, verification, and compliance in industrial, laboratory, manufacturing, and commercial contexts.

Self-adhesive backing enables simple installation on most surfaces. Highly flexible foil material accommodates curved surfaces. Compact dimensions fit narrow spaces inaccessible to thermometers. Irreversible colour change facilitates permanent heat detection.

Quick response time of 2 to 3 seconds for rapid temperature monitoring. Wide temperature range suitable for high-temperature applications. Versatile usage across transportation, food, automotive, aerospace, and electrical sectors.
