Compass Cryogenics 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
