Monitor uses the proven scientific principle of diffusion which involves the gradual mixing of molecules of two or more substances for measuring personal exposure in work areas of industries.

• Ethylene oxide monitor utilises brominated carbon to collect and convert the reactive ethylene oxide to a more stable chemical derivative, 2-bromoethanol
• Compound then desorbed with methylene chloride in methanol
• Accuracy within ±25% for 8-hour samplings at 1 ppm
• Accuracy within ±35% for 8-hour samplings at the action limit

18-month shelf life.
