Abstract
A new and improved combination pressure gauge and relative humidity indicator for use upon a compressed air or gas too, such as, for example, a paint spray gun, comprises a housing within which a pressure transducer, for determining the pressure level of the incoming compressed air or gas, and a humidity sensor, for determining the relative humidity of the incoming compressed air or gas, are disposed and contained. A first end portion of the housing has a first coupling mounted thereon for connection to an inlet port coupling of the paint spray gun, while a second end portion of the housing has a second coupling mounted thereon for connection to a compressed air or gas line of a compressed air or gas supply source. In this manner, the combination pressure gauge and relative humidity indicator can be readily incorporated within the fluid flow line of the compressed air or gas so as to be separably and independently useable with any compressed air or gas tool.
