Description
Fluke TiS55 Thermal Camera Repair
The Fluke TiS55 is a Performance-series thermal imager – the workhorse tier, simpler optics and a fixed or manual focus, built to be carried daily by technicians who need a reliable image rather than the highest resolution available. Simpler construction means the faults concentrate in the parts that get handled.
The Fluke TiS55 is repaired at June Company by technicians who work on thermal imaging equipment daily, for electricians, HVAC technicians, maintenance crews, and facilities teams. 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 TiS55 problems we fix
- Laser pointer failure.
- Battery will not hold charge or unit will not power on – the pack, the charging circuit and the power section, tested separately.
- Display or touchscreen failure.
- 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.
- Focus mechanism stiff or slipping.
- Temperature readings drifted – the measurement path rather than the image – a picture that looks fine can still be reporting the wrong number.
- Images not saving or SD card not recognised.
FAQs
Do you handle imagers that were dropped? Yes. Impact damage tends to affect the lens assembly, the display and the detector mount, and all three are repairable.
It powers on but the image is blotchy and gets worse the longer it runs – fixable? Yes. That pattern points at the internal shutter failing to recalibrate the detector, and it is a common repair on this series.
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.
