The EVM Series of 3M™ Monitors, monitor both particulates and air quality in one compact instrument. This durable, easy to use model provides simultaneous worksite area monitoring of:
  • Particulate mass concentrations (0.1-10 um)
  • Select volatile organic compounds
  • Temperature
  • Relative humidity
  • Carbon dioxide
  • Select toxic gases
  • Air velocity (with purchase of optional accessory)
 
EVM-7 Particulate & Air Monitor
  • Simultaneous measurement of particulate and gas concentrations
  • Dial-in rotary impactor
  • Built-in sampling pump for gravimetric analysis
  • External temperature and relative humidity sensor helps ensure accurate readings
 
EVM-4 Indoor Air Monitor
  • Multi-sensor instrument designed for indoor air quality investigations.
  • Toxic Gas (choose from nine sensors)
  • Relative Humidity
  • Carbon Dioxide
  • Temperature air exchange rates and dew
 
EVM-3 Particulate Monitor
Specialises in real-time direct reading of particulate concentrations. EVM-3 measures:
  • Particulates (mass concentration)
  • Temperature
  • Relative Humidity
