Uncertainty in temperature measurement
WebMeasurement Uncertainty – Principles and Implementation in QC Chart 6 5.4.6.2 Testing laboratories shall have and shall apply procedures for estimating uncertainty of measurement . In certain cases the nature of the test method may preclude rigorous, metrologically and statistically valid calculation of uncertainty of measurement. WebThe best method for achieving ambient temperature compensation is to measure the temperature of the camera and optical path in up to three different locations. The measurement data is then included in the calibration equation. This can ensure accurate readings through the entire range of operating temperatures (typically ‐15ºC to 50ºC).
