testo teplotné meracie prúžky 0646 0073, +100 až +140 °C, 10 prúžkov

The testo 0646 0073 temperature measuring strips provide a simple, irreversible way to confirm whether a surface has reached a specific temperature threshold. Unlike electronic loggers that require setup and data retrieval, these self-adhesive strips change colour from white to black the moment the rated temperature is exceeded, leaving a permanent visual record.

Highlights

• Eight temperature points per strip: 100, 105, 110, 115, 120, 125, 130, 135, 140 °C
• Irreversible colour change from white to black at each rated point
• Self-adhesive backing for quick attachment to clean, dry surfaces
• Accuracy of ±1.5 °C across the full range
• Pack of 10 strips, each 50 x 18 mm

In daily use

Apply a strip to a component, motor housing, or process line before operation. After the process, inspect the strip: any temperature point that has turned black indicates that the surface reached at least that temperature. Because the change is permanent, the strip serves as a tamper-proof record for quality assurance and process control.
