The Fieldpiece DR82 is Australia's go-to mid-range infrared refrigerant leak detector for commercial HVAC technicians. This complete guide covers how the DR82's infrared sensor works, where it outperforms heated diode technology, correct zeroing and probe technique for real Australian jobs, and how it compares to the TEK-Mate, SRL2, and D-TEK Stratus. Essential reading for any tech considering the step up to professional infrared detection.

Confused about heated diode vs infrared leak detector technology? This guide explains how each sensor works, compares sensitivity, false alarm resistance, and sensor lifespan side by side, and tells you which technology suits residential splits, commercial HVAC, and refrigeration work in Australia.

Picking the wrong refrigerant leak detector costs you time, refrigerant, and repeat call-backs. This complete Australian buying guide compares every detector type — heated diode, infrared, UV dye, ultrasonic — across budget tiers from under $300 to $700+. Covers top brands including Inficon, Fieldpiece, and Javac, with straight application advice for residential splits, commercial HVAC, and large refrigeration systems.

A leak detector is only as good as its maintenance. In Australian HVAC work, a poorly stored, dirty, or ageing detector can lead to missed leaks, false alarms, wasted labour, and repeat visits. This guide explains leak detector calibration, sensor life, servicing, storage, and replacement in simple practical terms for techs working with R32, R410A, and R22 systems across Aussie conditions.
