TSI EVM Environmental Monitors

Descriptions of TSI EVM

The TSI Quest EVM Environmental Monitors simultaneously measure particulates and gas concentration in real-time. These monitors measure select toxic gases, volatile organic compounds (VOCs), relative humidity and temperature.

Features and Benefits
▪ 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 of measurements
▪ Time history data logging and compatibility with Detection Management Software makes
analysis efficient
