Quest EVM-7 Advanced Particulate & Air Quality Monitor

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. This durable, easy-to-use model provides simultaneous worksite monitoring of: particulate mass concentrations (0.1-10 um), select volatile organic compounds, select toxic gases, carbon dioxide, relative humidity, temperature, and air velocity (with purchase of optional accessory).

All models include:

  • Two 37mm Gravimetric Filter Cassettes (for pump protection; one in unit and one spare)
  • 12V DC Universal Input Power Supply
  • USB Cable
  • Silicone Dielectric Grease for Impactors
  • 10 pack Pump Protection Filters
  • PID Electrode (Grid) Pellet
  • Dust Zero Calibration Filter Assembly
  • Toxic Calibration Adapter
  • Storage Case

Available options:

  • EVM-7: Base unit with PID(ppm) and CO2 sensor
  • EVM-7/CO: Base unit with PID(ppm), CO2 sensor, and CO sensor
  • EVM-7-ppb: Base unit with PID(ppb) and CO2 sensor
  • EVM-7/CO-ppb: Base unit with PID(ppb), CO2 sensor, and CO sensor
