Abstract
A portable, environmental monitoring apparatus comprising a self-contained and internally powered data acquisition and recording device for continuously monitoring the environmental conditions in an enclosed space, preferably a computer control room. The apparatus includes sensors which measure pressure, temperature, relative humidity and the corrosive nature of the environment. The signals generated by the sensors and the atmospheric corrosion indicators are stored in a memory module included in the circuitry of the recording device. The memory module interfaces with an IBM-type PC for off loading the data and storing it on a floppy disc.
