Monitoring Badge


Product Details


The SafeAir System offers immediate visual confirmation of a specific chemical hazard.  SafeAir badges are available for more than 20 different toxic industrial chemicals.


The highly sensitive and selective sensor in the SafeAir badge is designed to show a homogeneous and stable color change, which appears as an exclamation point when a particular chemical is present. A color comparator is available to pinpoint the exposure dose of a toxic chemical.  These specially designed color charts feature a slot for the badges. Once the badge is inserted, the user can turn a wheel to match the colors. The exposure dose is indicated in the exposure dose window.


ChromAir is designed to detect exposure dose levels to specific toxic chemicals. Because it relies on diffusion, there is no pump to operate. The patented design provides immediate and accurate results throughout the sampling period.


The ChromAir badge offers six exposure levels, with most indicating from one-tenth to two times the Permissible Exposure Limit (PEL) Time Weighted Average (TWA) for an eight-hour work period. To determine the average concentration, users can locate the highest cell with a color change and divide the corresponding dose level (parts per million times hour) by the sampling time in hours.
