Fits advanced handheld IR/contact work where you need a Fluke 568 with −40 to 800 °C IR range, 50:1 D:S, Type K input, 99-point logging, and USB with FlukeView Forms.
Key advantages
- IR range — −40 to 800 °C (−40 to 1472 °F); D:S 50:1; 8–14 µm; <500 ms
- Contact — Type K −270 to 1372 °C (bead included −40 to 260 °C)
- Logging / PC — 99-point log; USB 2.0 + FlukeView Forms
- Accuracy — IR ≥0 °C: ±1% or ±1.0 °C (whichever greater)
- Display — Soft-key menus; Min/Max/Avg/Dif; Hi/Lo alarms; emissivity table
Typical applications
- Higher-temperature IR scans than 566.
- Documented routes with FlukeView Forms.
- Smaller targets via 50:1 D:S.
Selection guide
- Range / D:S — 800 °C / 50:1 vs 566
- USB workflow — FlukeView Forms yes/no
- Emissivity — Table vs numeric
- Power — 2× AA; USB when tethered
Common mistakes
- Underfilling spot size even at 50:1.
- Skipping USB cable/software if logging to PC is required.
- Wrong emissivity on reflective surfaces.
