EVM-4

The EVM-4 monitor is specifically designed for indoor air quality studies, and measures temperature, relative humidity, air velocity, toxic gas, and carbon dioxide. Does not measure particulates or select volatile organic compounds.

*Includes base model with CO2 Sensor, two Dummy Sensors (used to seal socket when no sensor is present), 053- 263 12V DC Universal Input Power Supply, 053-575 USB Cable, 074-726 Toxic Calibration Adapter and 074-718 Storage Case.*
  • Particulate, gas and photoionization detector (PID) measurement from a single device
  • 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 Detection Management Software makes analysis efficient
