EVM-7 Applications
- Worksite monitoring
- Industrial hygiene surveys
- Military site evaluation
- Aircraft and train environment sampling
- Construction/mining site monitoring
- Engineering studies
- Industrial fenceline monitoring
- Remediation sampling
- IAQ walk-through and stationary studies
- Air quality assessment
- VOC screening and monitoring
- Regulatory compliance
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 QuestSuite Pro II 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

QuestSuite Pro II System
Software
Expand data management and reporting capabilities
for NoisePro, SoundPro SE & DL, HavPro, and QUESTemp° 34/36
instruments with QuestSuite Pro II (QSPII) Software. Manage an entire
instrument inventory, including non-Quest instruments, from one easy-to-use
software application. Program QuestSuite Pro II Software to automatically
prompt when calibrations are due for inventory instruments. QuestSuite
Pro II allows email direct from an error screen to technical support.
Data deletion, import, and export occur at increased speed and data
export to network drives is facilitated. Single and multiple user licenses
are available. Contact SKC for
multiple user information.
