What does distance-to-spot ratio mean on Fluke IR thermometers?

Distance-to-spot ratio (D:S) tells you how large an area the thermometer measures at a given distance. An 8:1 ratio means at 80cm distance, the measurement spot is about 10cm in diameter. A 10:1 ratio gives a tighter spot at the same distance. Higher D:S ratios are better for measuring small targets or measuring from farther away — important for electrical panels where you need to isolate individual components.

Can I use a Fluke IR thermometer for food safety applications?

Yes, Fluke IR thermometers are widely used in food processing and cold storage for non-contact temperature verification. The Fluke 59 MAX is a cost-effective choice for checking food surface temperatures, cold room monitoring, and HACCP compliance. Note that IR thermometers measure surface temperature only — for internal food temperature, you still need a probe thermometer.
