Abstract : The patent relates to the atmospheres of a salt chamber and a test chamber which are transported in a closed-loop back and forth between the chambers, the loop including heating and cooling means for adding and subtracting equal temperature increments as the atmospheres are in transit between the chambers. The salt chamber remains at a constant temperature to maintain a stabilized relative humidity. Heat added to the stabilized atmosphere as it passes to the test chamber is subtracted during the return flow. The relative humidity of the test chamber varies with the heat increments to permit RH sensors and the like to be calibrated.
