The kit consists of a series of sealed glass tubes containing a chemical. Different tubes for different contaminants. You break the ends off the glass tube and pump a sample of air from your compressor through it. The chemical in the tube changes colour and you read off from a colour chart the level of contaminant in the sample. The tube for oxygen gets very hot!
Try asking your Local Authority Enviromental Health Department if they can supply an analysis service. A club I used to belong to did this.
