MEASUREMENT TOOLS
Put a number to the question.
Useful estimates, with the assumptions left in view.
Distance-to-spot calculator
Estimate the measurement spot of an infrared thermometer.
Geometry estimate only. Check the instrument’s optical diagram, minimum focus distance and stated energy coverage. A laser dot is not the measurement spot.
IR spot
83.3mm
Target exceeds the estimated spot
Read the measurement, not just the display.
Understand reflections, target size and what your instrument actually records.
