ChromAir Direct Read Colorimetric Badges

Description

ChromAir badges are 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.

The 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.

For higher 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 badges.

Features

• Immediate on-site results
• Easy to read color change
• Highly sensitive and selective
• Exposure data read directly from badge
• Immediate response for short term exposure measurements
• Measures TWA exposures
• No laboratory analysis needed
• Lightweight and cost effective for personnel and area monitoring

*The ChromAir mercury and glutaraldehyde badges have five levels.

**The ChromAir mercury badge scale is mg/m³ x hr. The glutaraldehyde STEL badge is in ppm.

Specifications

*3 ppm H₂S causes color development in cell 1, 10 ppm H₂S causes color development in cell 2.

**Ozone monitor is ten times more sensitive to ozone than to nitrogen dioxide.

***Coefficient must be applied to scale printed on badge.
