The 3M 3500 passive badge monitor uses a single charcoal sorbent wafer for collecting organic vapors. Accuracy of +/-25% at a 95% confidence level for many workplace contaminants. Analysis not included.
The 3M™ Organic Vapor Monitor 3500 uses the proven scientific principle of diffusion, which is the gradual mixing of molecules of two or more substances. It has a single charcoal sorbent wafer for easy collection of organic vapors and can be used for most applications. It has an 18-month shelf life.
Each lightweight monitor badge simply attaches to the operator's lapel, and because there are no cumbersome pumps, pipes and connections, there is no compromise on comfort.
After the specified exposure period, the monitor badges can be sent for analysis to an UKAS accredited laboratory such as Casella CEL, RPS Laboratories and The Institute of Occupational Medicine.
