THE EFFECT OF ATMOSPHERIC TRANSMISSION ON THE RELIABILITY OF THE RESULTS OF THE VERIFICATION OF INFRARED THERMOMETERS
(pp. 26-31)

Abstract. The spectral range the infrared thermometers AKIP contains strong absorption bands of radiation by water vapor in the atmosphere. It is established that the deviation of temperature and relative humidity significantly affects the measurement result. If you change the influencing factors within the set limits the change of the readings of the infrared thermometers is 50 % margin of error. This affects the reliability of verification results. The reliability of the results of verification may be evaluated by Monte Carlo method. It is established that the probability of error of the first kind reaches 13,8 %. The probability of error of the second kind reaches 22 %. To reduce the chance of error checking is proposed to bring the results of the measurements to the nominal values of the influence quantities. This will allow 1.4 – 1.9 times to reduce the probability of error. For calculation of amendments is proposed to use a simple function that approximates table Passman–Larmora.

Keywords: verification, infrared thermometers, passing the atmosphere, verification error 1 and 2 kind.
