Testo Mini Indicator

Testoterm Mini Indicators

The Testoterm Mini Indicators are compact, self-adhesive temperature-sensitive labels designed for highly precise thermal monitoring. At just 15 mm in diameter, they are engineered for extremely tight spaces where traditional measuring strips or electronic probes simply cannot fit. Once a specific temperature threshold is breached, the relevant indicator point changes color permanently within 2 to 3 seconds, providing indisputable visual proof of overheating.

Primary Functions & Applications

Supplied in convenient booklets of 10, these miniature foils stick directly to the measurement object. Because their color change is irreversible, they are the perfect continuous monitoring tool for long-term applications or moving components. Key functions include:

• Very Small Objects: Monitoring delicate circuit boards, micro-components, and tight mechanical assemblies.
• Moving & Rotating Parts: Affixing directly to high-speed shafts, bearings, and motors where wired probes would tangle or break.
• Quality Assurance: Permanent documentation for warranty claims, proving whether a machine or component was pushed past its thermal limits.
• Aerospace & Automotive: Fast, reliable thermal diagnostics on engine components without complex setups.

General Specifications

Tradie Pro Tip: These indicators are highly sensitive. When peeling them from the booklet, try to handle them by the edges using tweezers if possible, and ensure the target surface is dry and degreased. This prevents body heat or grime from interfering with the adhesive or the reading.
