What is the evm-7?

The EVM-7 - is a durable yet lightweight instrument designed for real-world use. It can be tripod mounted or hand-held, making it well suited for a variety of area monitoring applications, including: Simultaneous Measurement of Particulate and Gas Concentrations - Reduces the need for multiple instruments and lowers the cost of ownership.

How does the evm-7 air quality monitor work?

The EVM Series Particulate Mass Concentration and Air Quality Monitors simultaneously measure particulates and gas concentration in real-time. The EVM-7 measures both particulates and air quality, and provides a lower cost of ownership by combining three instruments into one.

What is the TSI quest evm-7 Environmental Monitor?

The TSI Quest EVM-7 environmental monitor is a benchtop aerosol mass concentration monitor, indoor air quality meter, and area gas detector in a single device. It measures relative humidity and temperature and can simultaneously measure and log mass concentration particulates, volatile organic compounds, carbon monoxide and carbon dioxide.

What is EVM and how can it be quantified?

As an error metric, EVM is closely related to all error sources within a system. We can quantify the EVM impact of all the impairments by calculating how they distort the received and transmitted signals. Let’s analyze the impact of several key impairments, such as thermal noise, phase noise, and nonlinearities, on EVM.
