ChromAir Monitoring Badges: Ammonia
The ChromAir badge is a colorimetric direct read monitor and a color comparison chart.
It relies on the principle of diffusion, therefore it requires no pump to operate.
Unlike traditional diffusion tubes, the patented design of the ChromAir badge provides a short and constant
diffusion path irrespective of the sampling time or concentration of the contaminant.
This unique feature provides accurate results immediately and throughout the sampling period.
ChromAir monitor provides the user with six exposure levels*. Most
ChromAir badges indicate from 1/10 to 2 times the time weighted average
for an eight hour work period. The scale** printed on the badges and
color comparators is based on exposure dose (parts per million time
hour (ppm x hr). To determine the average concentration, the user
locates the highest cell with a color changes and divides the
corresponding dose level (ppm x hr) by the sampling time in hours
(hrs). If the sampling time is 2 hours and badge reads 40 ppm x hr, the
average concentration is 20 ppm.
resolution and wider range, the ChromAir badge may be used in
conjunction with the ChromAir color comparator. The color scales on the
color comparators identically match the colors formed on the ChromAir
