Optical gas analyzer PEM-2M

Purpose

The complex is used as channels of continuous emission monitoring system, CEMS.

prod5

Advantages

  • A possibility of switching in outer devices (dust counter, flowmeter)
  • Stepwise measurements from several sources (optional);
  • Flexible customized configuration of the complex

The work principle

The complex is a stationary automated multi-channel instrument for measuring of continuous action.

Applied measurement methods:

  • The optical absorption method in the infrared spectral region (non-dispersive infrared, NDIR) to identify: - carbon oxide (CO),
  • nitrogen oxide (NO),
  • nitrogen dioxide (NO2),
  • nitrogen oxides NOx (in equivalent of NO2),
  • sulfur dioxide (SO2),
  • carbon dioxide (СО2),
  • The electrochemical method based on zirconium dioxide to identify oxygen (О2),

 

The PEM-2M.1 consists of: 

An analytics box with a sample preparation system

  • A probe with a heated filter
  • A heated sampling line
  • Aspiration modules

Gas switch (for switching several measurement points)
