Simultaneous particulate & gas concentration measurement in confined spaces.

Measure particulates in real-time.

The EVM-7 monitors both particulates and air quality in one compact instrument. The EVM-7 provides a lower cost of ownership by combining three instruments into one.

  • Measures upto 7 different parameters
  • Simultaneously measure Particulates, Volatile Organic Compounds, Toxic gas, CO2, RH, Temp, & Air velocity
  • Time history Data logging 
  • Displays measurement of levels, Min, Max, AVG, STEL & TWA
  • Dial-in rotary impactor.
  • 90 degree light scattering photometer.
  • Built-in sampling pump for gravimetric analysis.

  • Economical investment.
    • Particulate, gas, and photoionization detector (PID) measurement from a single device
    • Less equipment to carry to job site; compact, user-friendly design
  • Proven process
    • 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
  • User Friendly.
    • Large, easy-to-read display with trend graphing for measurements
    • Time history data logging and compatibility with 3M TM Detection Management Software makes analysis efficient
