Quest EVM-7 Environmental Monitor


Orderable Items The Quest EVM-7 environmental monitor simultaneously measures particulates, volatile organic compounds (VOCs) with PID, toxic gas, carbon dioxide, relative humidity, temperature, and air velocity. Use the EVM-7 for worksite monitoring, industrial hygiene surveys, air quality assessment, VOC screening and monitoring, military site compliance, and regulatory compliance.



 
EVM-7 Key Features:

  • Simultaneously measures particulate and gas concentrations
    • Reduces the need for multiple instruments
    • Measures VOCs (with ppm-level PID), toxic gas, carbon dioxide, relative humidity, temperature, and air velocity (with Air Probe-10 accessory)
    • Optional ppb-level PID available---ppb-level VOC measurements can be converted to µg/m3 in Detection Management Software (DMS) for comparison to LEED TVOC limit

  • Dial-in rotary impactor
    • Twist and click selection of PM2.5, PM4, PM10, or TSP* without disassembly and external cyclones

  • 90-degree light scattering photometer
    • Provides real-time particulate measurement and display

  • Built-in compensating sample pump
    • Simultaneous gravimetric sampling on a 25 or 37-mm internal filter cassette

  • Smart auto-recognized toxic gas sensors

  • Displays Level, Min, Max, Avg, STEL, and TWA in 6 languages

  • Trend graphing for all parameters
    • Carbon dioxide trending algorithms for calculation of room air exchange rates available with DMS

  • Menu-driven user interface with 10 push buttons/4 softkeys

  • Time history datalogging

  • Specialized models available for IAQ analysis (EVM-4) and particulate monitoring (EVM-3) (within the instrument’s measurement range)

* Photometer can detect particles up to 100 µm; however, accuracy is reduced for sizes greater than 10 µm.

 

Additional EVM-7 Features:

  • Factory calibrated relative to ISO 12103-1, A2 (Arizona Road Dust)


  • Site correction factors for particulates (user supplied)


  • Auto run and security code protection for unattended monitoring


  • Real-time measurement with once-per-second update rate


  • User selectable digital output for external functions

Monitor multiple air quality hazards/parameters using one instrument with the Quest EVM-7 environmental monitor. EVM-7 simultaneously measures particulates, volatile organic compounds (VOCs) with PID, toxic gas, carbon dioxide, relative humidity, temperature, and air velocity (with accessory probe). Two instruments in one means lower cost of ownership and elimination of multiple instruments.

Specialized EVM Models
EVM-4 and EVM-3 feature the durability, quality, and overall design of the EVM-7 but provide a sensor configuration for specific applications.

  • EVM-4 for Comprehensive IAQ Analysis Monitors and logs CO, RH, temperature, and CO2 (with DMS Software). Optional sensor accessories are available for air velocity, VOCs, particulates, and an alternate toxic gas.

  • EVM-3 Real-time Direct-reading Particulate Monitor Measures and logs particulate mass concentration (PM2.5, PM4, PM10, or TSP*), temperature, and RH. Optional sensor accessories are available for air velocity, CO2, VOCs, and CO or other toxic gas.

 


Detection Management Software (DMS)
Detection Management Software (DMS) makes it easy to retrieve, manipulate, report, share and store data collected by Quest datalogging instruments for noise dosimetry, sound measurements, heat stress assessment, indoor air quality evaluation and environmental monitoring. Features include:

  • Quick, easy navigation
  • Data sorting and fast report generation
  • Click, drag, and drop report/graph customization
  • Support for Acrobat PDF
  • Advanced reporting and analysis
