Description
Fluke TiR4 Thermal Imager Repair
The Fluke TiR4 is a building-diagnostics thermal imager. The TiR line was tuned for thermal sensitivity rather than raw temperature range, because finding moisture intrusion, missing insulation and air leakage means resolving fractions of a degree across a wall, not measuring a hot bearing.
Certified technicians at June Company service the Fluke TiR4 for building inspectors, energy auditors, restoration contractors, and home-performance professionals. Every imager is repaired at component level and its temperature accuracy verified against reference standards before it ships back, with the measured results documented.
Common Fluke TiR4 problems we fix
- Battery will not hold charge or unit will not power on – the pack, the charging circuit and the power section, tested separately.
- Images not saving or SD card not recognised.
- Loss of thermal sensitivity – the fault that matters most on this series – small temperature differences stop resolving and moisture patterns disappear into the background.
- Image degrading between shutter cycles – the internal NUC shutter, which recalibrates the detector every few minutes – when it sticks the image drifts and blotches until the unit is power-cycled.
- Dead pixels or fixed pattern noise – microbolometer detector faults, which show as permanent spots or a grid pattern that no amount of re-focusing clears.
- Humidity or dew-point calculation errors.
- Temperature readings drifted – the measurement path rather than the image – a picture that looks fine can still be reporting the wrong number.
- Display or touchscreen failure.
FAQs
I can no longer see moisture patterns I used to pick up easily – what is that? Loss of thermal sensitivity, usually the detector or the shutter. It is the characteristic TiR failure and it is repairable.
Does a repair restore the sensitivity spec, not just the image? Yes. Sensitivity is verified as part of the repair, because on a building imager it is the specification that actually matters.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
