Morphix 380018-10 Gas Monitoring Badges; Mercury, 10/Box from Cole-Parmer

The ChromAir badge is a colorimetric direct-read monitor that relies on the principle of diffusion to accurately determine the concentration of gas present in your environment. Most badges indicate from 1/10 to 2 times the Time-Weighted Average for an 8-hour work period. Readings on the badge indicate levels in units of mg / m3 * hr. Dividing this value by the length of its exposure time gives your resulting concentration in mg / m3. The range of the Mercury badge reads from 0.125 – 1.6 mg / m3 * hr. The purchase of a MOR-384003 Color Comparator extends this range to 0.12 - 3.2 mg / m3 * hr. (Sold here as a 10-pack. Morphix Part # 380018-10) Badge clips are sold separately.
