Temperature indicator stickers give Australian HVAC technicians passive, always-on surface-temperature monitoring across compressors, motors, switchboards, pipework and refrigeration cabinets — without power or data connections. This guide maps the right indicator format to each equipment type, covers threshold selection for Australian climate conditions, and includes an implementation checklist for service teams managing large commercial portfolios.

Testoterm Measuring Points are 14 x 14 mm single-threshold irreversible labels sold in booklets of 50 — designed for QA checks, warranty validation and recurring fleet inspections across HVAC motors, compressors, control cabinets and plant-room equipment. This guide covers threshold selection across the 65–121°C range, placement guidance, comparison with Mini Indicators, and logging and replacement workflow.

Testoterm Mini Indicators are Ø15 mm round irreversible heat labels designed for compact HVAC components, small motors, bearings and tight spaces where larger strips won't fit. This guide covers the 15 mm format, available temperature ranges from 116–138°C through 199–224°C, how to read multi-point activation, installation requirements, and when to use Mini Indicators instead of Measuring Points.

Testoterm temperature indicators are irreversible, self-adhesive labels that permanently record when a surface exceeds a rated heat threshold. This technical guide explains how the colour-change chemistry works, how to choose the right threshold, which format suits your application, and how to document heat events correctly across HVAC compressors, motors, switchboards and plant-room equipment.
