The 3M™ EVM Environmental Monitors EVM-7 monitors both particulates and air quality in one compact instrument. The EVM-7 provides a lower cost of ownership by combining three instruments into one.
1.Built-in sampling pump allows to capture particulates for laboratory testing
2.Time history data and data logging feature for enhanced reporting and measurement
This durable, easy-to-use model provides simultaneous worksite monitoring of: particulate mass concentrations (0.1-10 um), select volatile organic compounds, select toxic gases, carbon dioxide, relative humidity, temperature and air velocity (with purchase of optional accessory). The EVM-7 includes base model with PID (ppm) Sensor, CO2 Sensor, one Dummy Sensor (used to seal socket when no sensor is present), two 37mm Gravimetric Filter Cassettes (for pump protection; one in unit and one spare), 53-263 12V DC Universal Input Power Supply, 53-575 USB Cable, 100-456 Silicone Dielectric Grease for Impactors, 74-080 PID Cleaning , 74-090 10 pack Pump Protection Filters, 74-720 Dust Zero Calibration Filter Assembly, 74-726 Toxic Calibration Adapter and 74-718 Storage Case.
