Environmental Monitor [EVM-3]
The EVM-3 provides real-time direct reading of particulate mass concentrations along with temperature and relative humidity measurements. The proprietary dial-in impactors allow for quick selection of particulate settings PM2.5, PM4, PM10 or TSP (within the instrument`s measurement range) without disassembly.
A built-in air sampling pump assists in the collection of particulates while the laser photometer provides real-time measurement. A standard 25 or 37 mm gravimetric cassette can be utilized for sampling and laboratory analysis and help provide correlation for real-time direct reading measurements.
Features:
- Less equipment to carry to job site; compact, user-friendly design
- 90 degree light scattering laser photometer measures particulates in real-time
- Proprietary technology for selecting particulate settings; no need for external cyclones
- Built in sampling pump allows for gravimetric analysis
- Large, easy-to-read display with trend graphing for measurements
- Time history data logging and compatibility with 3M Detection Management Software makes analysis efficient
- Proprietary “dial-in” technology enables fast, easy selection of 4 different particulate size settings
- Eliminates the need to switch out cyclones for different measurement parameters
- Enables real-time measurement of particulates
- Allows user to easily capture particulate samples for on/off-site analysis
- Identify and confirm particulate concentration in question
