Testo 350 | Flue gas analyzer
Product Description
The portable flue gas analyzer testo 350 is the ideal tool for professional flue gas analysis. The Control Unit is the removable operation and display unit of the testo 350. The presentation of the measurement values takes place via the colour graphic display. Thanks to the internal memory, measurement data can be transferred from the analyzer box to the Control Unit. If required, several analyzer boxes can be operated and controlled with one Control Unit. The measurement technology is situated in the analyzer box. The robust housing has integrated impact protection.
Downtimes due to contamination of the instrument are almost completely eliminated. Inherently closed chambers protect the interior of the instrument from dirt from the surroundings. Operation can also be carried out in direct connection to a PC or notebook or via Android smartphone or tablet with the free App, as an alternative to the Control Unit. After programming, the analyzer box is able to carry out measurements and store measurement data independently.

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.
Measurement capabilities of testo 350:
• O2 • NO • HC
• CO • NOlow • Velocity
• COlow • NO2 • Pressure
• NOx • SO2
• CO2 • H2S

Applications
Service measurement on gas turbines
Gas turbines are subject to flue gas limit values which are to be adhered to during operation and regularly checked depending on the size of the system. After commissioning and maintenance work, the system’s emission values are checked for adherence to limit values and also the manufacturer’s specifications, and documented if necessary.
Due to the low NO concentrations, emission measurements during inspection and adjustment work on LowNOx gas turbines need to be extremely accurate. The portable flue gas analyzer testo 350 featuring the combination of NO2 sensor and special NOlow sensor with a resolution of 0.1 ppm enables precisely these requirements to be met. In addition, the integrated gas preparation and special flue gas probe with patented special hose provide protection against NO2 absorption and allow measured values to be compared, irrespective of date and ambient conditions.
Analysis of the gas atmosphere (thermal process)
The flue gas analysis is used for thermal process monitoring in process combustion systems, such as in continuous furnaces for the glass, ceramics and construction material sector, or in steel melting and hardening furnaces, etc. In processes of this kind, substances may pass from the product being processed into the flue gas, increasing the usual emissions produced by the combustion system.
vice versa, pollutants may pass from the gas and become part of the product being processed. The flue gas analyzer testo 350 can be used to pursue two main goals: monitoring of the process-related gas atmosphere to ensure the optimum quality of the processed products. The gas analysis provides information for process-related measures, such as the design of the furnace interior, flame control, fired product and furnace temperature, or the combustion air supply. At the same time, the gas analysis contributes to optimum operation of the system in terms of operating costs and safety.
Measurement on industrial burners
For whichever purpose combustion systems are used, whether for heating, generating electrical power, steam or hot water, for the production or surface treatment of certain materials, or to incinerate waste and scrap materials, the best possible way of managing combustion and incineration definitely includes the right knowledge about the compositions of fuels and combustion air, and their relationship to one another. Even how they are combined is crucial. Mobile measuring technology allows all relevant gases to be analyzed and optimum combustion processes therefore to be achieved.
The purpose of using a portable flue gas analyzer is to test the environmentally sound operation of combustion systems and optimum utilisation of the system. This means that a combustion system can be adjusted to its optimum working range to enable it to meet or come within stipulated emission limit values, while achieving a maximum level of efficiency in terms of combustion. The accurate flue gas analyzer testo 350, suited to tough practical conditions, is not only used for commissioning purposes, but also for repeat gas analyses during operation.
