Chromair Direct Read Badges

ChromAir is designed to detect personal exposure levels of specific toxic chemicals

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

Some ChromAir badges can be used with colour comparators to pinpoint higher resolution and wider range.

ChromAir badge sensors are coated on an inert surface. Morphix design offers a more uniform color change, longer shelf-life and minimises environmental effects like humidity, temperature, face velocity and chemical interferences compared to Sure-Spot" dosimeter badge and the Drager Bio-Check
