This portable monitor not only acts as a personal alarm, but will also calculate the time weighted average (TWA) of an individual’s exposure to N2O. The G200 also acts as a leak detection device and will store up to 1,000 readings to be used for graphs and data analysis. The G200 is able to provide readings from 0-1,000ppm in less than 40 seconds and 0-10,000ppm in leak detection mode, safeguarding both health professionals and patients.
