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.

In combination an enclosed space, an apparatus for monitoring and recording the environmental conditions existing in said enclosed space, a case for housing said apparatus, and means for mounting said case in said enclosed space, wherein said case includes openings for exposing said apparatus to the environmental conditions existing in said enclosed space and wherein said apparatus comprises: (a) a plurality of environmental data sensors located on a sensor board mounted in said case and adapted to be responsive to changes in temperature, relative humidity and atmospheric pressure occurring in said enclosed space; (b) a microprocessor circuit coupled to said data sensors for scanning signals from said data sensors and recording those signals which deviate from pre-set conditions and which remain in effect for a prescribed period of time; and, (c) a digital memory device coupled to said microprocessor circuit for collecting and storing recorded signals from said microprocessor circuit on a time zero basis.
