How do I measure the levels of exposure in my surgery environment?

• Use of diffusion pens  worn in the breathing zone for a typical r a session, then returned to the Laboratory for evaluation.
• Using an Analyser such as the latest G200.  This unit is designed to accurately verify the level of exposure and can be used to check both background and breathing zone levels of nitrous oxide.  This model was released in March 2010 and replaces the earlier PM 3010 which was discontinued around 2006.
