Abstract

The aim of this paper is to present the results of an interlaboratory comparison in temperature and relative humidity, among eleven laboratories, that was coordinated by the National Institute of Metrology, Quality and Technology (Inmetro, Brazil). As transfer standard, a thermo-hygrometer was used. The intercomparison was carried out in the range from 20 %rh to 90 %rh (at 20 ºC and 30 ºC) and from 20 ºC to 40 ºC. The performance of the intercomparison was judged by calculating the normalized error. Results from the majority of the labs agreed well with those of Inmetro.
