Testo 350 Industrial Flue Gas Analyser

The Testo 350 Industrial Flue Gas Analyser is a gas exhaust analyser comprised of two parts:

1x Testo 350 Control Unit
1x Testo 350 Analysis Box

Designed for conducting industrial emissions measurements in the field, the Testo 350 Industrial Flue Gas Analyser can be used to analyse emissions from:

Industrial motors
Burners
Gas turbines
Thermo-processes

Testo 350 Control Unit Overview

The Testo 350 Control Unit controls emissions measurements. It can be used to operate the Testo 350 Analysis Box remotely which is particularly useful when working on larger systems. Via the clearly structured graphic display, you can choose one of four different application modes: burner, gas turbine, motors, or user-defined. Once the operating mode has been selected, the Testo 350 Control Unit will guide you through the measurement process, improving the ease, efficiency, and convenience of testing.

Testo 350 Analysis Box Overview

The Testo 350 Analysis Box contains the sensors required for measuring emissions. As standard the Testo 350 Analysis Box includes an oxygen (O₂) sensor; however, you can choose to configure the tester with up to five more sensors. Select from:

Carbon Monoxide (CO): 0-10000ppm
Carbon Dioxide (CO₂): 0-500ppm
Nitrogen Oxide (NO): 0-4000ppm
Low Range Nitrogen Oxide (NO_low): 0-300ppm
Nitrogen Dioxide (NO₂): 0-500ppm
Sulphur Dioxide (SO₂): 0-5000ppm
Hydrogen Sulphide (H₂S): 0-300ppm
Hydrocarbons (C_xH_y)

The Testo 350 Analysis Box always displays the current reading. When high gas concentrations are detected, a measuring range extension function is automatically activated enabling unlimited measurement. Additionally, the Testo 350 Analysis Box offers an array of diagnostics functions that deliver easy-to-understand readings and information.

Additionally, this ergonomically designed flue gas analyser features an underside opening that provides convenient access to pumps and filters, enabling easy replacement and/or cleaning in the field. Other practical features include USB, Bluetooth or CANCase interfaces that support operation from devices other than the Testo 350 Control Unit such as a PC or notebook.

Furthermore, once the Testo 350 Analysis Box has been programmed, it can be left to carry out the required tests independently and save the results. These results may be transferred directly to the Testo 350 Control Unit.
