In some settings, monitoring the amount of exposure is the key to safe working conditions. ChromAir® is designed to detect exposure dose levels to specific toxic chemicals. The ChromAir® chemical exposure monitoring 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.
For higher resolution and accuracy, the ChromAir® badges can-be-used with the ChromAir® color comparators. The color scales on the color comparator identically match the colors formed on the ChromAir® badge.
Features
• Easy to read color change
• Highly sensitive and selective
• Exposure data read directly from badge
• Measure TWA exposure
• Immediate response for short-term exposure measurements
• Patented design minimizes effects of humidity and velocity
• Light-weight and cost effective for personnel and area monitoring
*1ChromAir® glutaraldehyde STEL badges are for 15 minutes of monitoring only. The scale on the badge is in ppm
*2ChromAir® mercury badge and color comparator scale is in mg/m3 hr
*3Coefficient must be applied to scale printed on badge
*4ChromAir® ozone badges are ten times more sensitive to ozone than nitrogen dioxide
