Matheson's Badge Dosimeters provide an economical, easy-to-use method for monitoring personal exposure to seven toxic gases. Each badge is an instant reading detector and provides an immediate color change in the presence of specific toxic gases. Additionally a color comparison chart (not available for carbon monoxide or ozone) also allows the user to evaluate limited exposures as well as up to eight hour time weighted averages.
These maintenance free badges do not need activation and are ready for immediate use. No expensive analysis equipment or air samplers are required. Each badge clips easily to collar, shirt pocket or hat. Or it can be used for area monitoring by affixing it to a wall or other support.
Each plaque weighs only 1/4 ounce and comes with a record form for recording employee name, date, time on, time off, elapsed exposure time and reading. Badges may be stored up to six months in unopened packs without deterioration. Usable life is one month after removing the badge from the package.
