Humidity cabinet employed at the National Bureau of Standards to determine the effect of atmospheric conditions on dielectrics under consideration as reference standards.
A. H. Scott is introducing a sample into the cabinet, which is equipped with a measurement cell.
A rubber glove, like the one on the left side of the box, will seal the opening.
Once the desired humidity is established, all further manipulation is done by an operator working through these gloves.
