Type of article: Article

Summary

BRIEFLY REVIEWS THE PRINCIPLE OF OPERATION OF A CAPACITIVE RELATIVE HUMIDITY INSTRUMENT. CLASSIFIES ERRORS INTO 2 BROAD CATEGORIES: SYSTEMATIC AND RANDOM AND NOTES THE EFFECT ON ACCURACY OF LINEARITY ERRORS, TEMPERATURE ERRORS, HYSTERESIS AND CALIBRATION ERRORS. CONCLUDES THAT CONTRARY TO COMMONLY HELD OPINION, ACHIEVING AN ACCURACY OF PLUS OR MINUS 2% RH WITH A RELATIVE HUMIDITY INSTRUMENT IS NOT A TRIVIAL MATTER, EVEN AT TEMPERATURES OF 293-298 K (20-25 DEG C). MANY OF THE INSTRUMENTS BEING SO SPECIFIED WOULD PROBABLY NOT PASS A SERIOUS TEST. (INT. BUILD. SERV. ABSTR. , GB., 23, N 4, 1988, 88-01204.
