Key parameters
Measuring range
IR −40 to 650 °C (−40 to 1202 °F); Type K contact −270 to 1372 °C; included bead Type K −40 to 260 °C
Accuracy
IR ≥0 °C: ±1% or ±1.0 °C (whichever greater); <0 °C: ±(1.0 °C + 0.1°/1 °C). Type K −40 to 1372 °C: ±1% or 1 °C
Output
Dot-matrix display 98×96; Min/Max/Avg/Dif; Hi/Lo alarms; data log 20 points with date/time
Supply
2× AA/LR6; battery life ~12 h laser+backlight on / ~100 h off
Ambient temperature
Operating 0 to 50 °C; storage −20 to 60 °C
Display
Soft-key graphical menus; two-level backlight; emissivity 0.10–1.00 or material table
Fits handheld IR and contact temperature checks where you need a Fluke 566 with −40 to 650 °C IR range, 30:1 distance-to-spot, Type K input, and 20-point data logging.
Key advantages
- IR range — −40 to 650 °C (−40 to 1202 °F); D:S 30:1; 8–14 µm; <500 ms
- Contact — Type K −270 to 1372 °C (bead included −40 to 260 °C)
- Accuracy — IR ≥0 °C: ±1% or ±1.0 °C (whichever greater)
- Display — Soft-key menus; Min/Max/Avg/Dif; Hi/Lo alarms; 20-point log
- Power — 2× AA; ~12 h laser+backlight / ~100 h off
Typical applications
- Electrical and HVAC IR scans.
- Contact Type K verification.
- Quick logs without USB (use 568 for USB/FlukeView).
Selection guide
- Range / D:S — 650 °C / 30:1 vs 568 higher range/50:1
- Logging — 20 points vs 568’s 99 + USB
- Emissivity — 0.10–1.00 or material table
- Laser — Class 2
Common mistakes
- Buying 566 when USB/FlukeView Forms is required — choose 568.
- Ignoring D:S fill factor on small targets.
- Wrong emissivity on shiny metals.
