Perchloroethylene Vapor Monitor
Catalog No. OV-80

Perchlorethylene is the most common chemical used in the dry cleaning industry.

ACS Vapor Monitor can be worn as a badge near the breathing zone to measure personal exposure, or placed in a room to measure area concentration.

Occupational safety standards are based on personal exposure monitoring of each employee who may be exposed to the vapor as a regular part of their job. Periodic monitoring of personnel and room concentrations is recommended
