Description

“Ideal for professional flue gas analysis and industrial emissions measurement on industrial engines, burners, gas turbines and in thermal processes: the testo 350 flue gas analyzer performs a variety of measuring and analysis tasks, impresses over the long term thanks to its heavy-duty industrial design and is also suitable for complex data acquisition.

The testo 350 flue gas analyzer comprises two units
The testo 350 Control Unit (separate product) with a clear graphic display, allows you to control emissions measurement. Operation is really easy: burner, gas turbine, engine and user-defined applications are available for selection in the menu. The Control Unit enables remote control of the analyzer unit even when there is a spatial separation of the flue gas pipe and the setting location – particularly recommended for emissions measurements on large plants.
The testo 350 analyzer unit is just what you need for carrying out emissions measurement, because it contains all the sensor technology and electronics. The testo 350 analyzer unit includes an O2 gas sensor as standard, but at least one additional sensor must be connected for commissioning (can be used with a maximum of 6 sensors). When connecting the optional sensors, you can choose between gas sensors for CO, CO2, NO, NO2, SO2, H2S or CxHy.

The measuring range extension enables unrestricted measurements to be carried out, even when there are high gas concentrations. In order to protect the sensor technology, the measuring range extension (dilution) is automatically activated when there are unexpectedly high gas concentrations. The measuring range of a selected sensor can be extended by a specific factor. The service opening on the underside of the instrument allows fast access to all relevant serviceable and wearing parts, such as pumps and filters, enabling users to clean or replace these. In addition, the testo 350 has numerous instrument diagnosis functions. Instrument notifications are output in cleartext, making them easy to understand. The current status of the flue gas analyzer is constantly displayed.”

USPs

• Increased measurement range for unlimited measurements even when gas concentrations are higher
• Easy-to-change gas sensors and easy access to wearing parts
• Increased measurement range for unlimited measurements even when gas concentrations are higher
• Easy operation of the analyzer unit via Control Unit or easyEmission software (both products available separately)
