Testo 0646 1065 testoterm +65°C Temperatuuraanduiding-etiketten, 50-pack, zelfklevend, 45 x 15 mm, wit naar zwart

Maintenance teams use these self-adhesive temperature indicating labels to monitor heat build-up in electrical cabinets, motors, bearings, and machinery. Each label provides a clear irreversible colour change from white to black when the surface reaches +65 °C, giving an immediate visual signal of overheating without any instruments.

Why choose it

The irreversible colour change ensures that even a brief over-temperature event is permanently recorded, allowing you to identify and address potential issues before they lead to failure. The compact size and strong adhesive make these labels easy to apply to a wide range of surfaces.

Ideal use cases

• Monitoring electrical cabinets and switchgear
• Checking bearing and motor temperatures
• Process control and machine maintenance
• Quality assurance in manufacturing

Good to know

Store labels in a cool, dry place between +6 and +36 °C to maintain their accuracy and shelf life. Avoid prolonged exposure to harsh chemicals or abrasion, as this may affect the temperature-sensitive element.
