EVM Environmental Monitors

Overview

The Quest EVM Series of Monitors are designed to 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)

There are 3 EVM models, each with different capabilities. Below is a simple product detail guide:

	EVM 7	EVM 4	EVM 3
Type of Monitor	Indoor Air Quality/Particulate Monitor (all-in-one monitor)	Indoor Air Quality (no particulate monitoring)	Particulate Monitor (no indoor air quality)
