    7. The Control Unit is the perfect companion to the testo 350 Analysis Box (sold separately), simplifying the control of emission measurements. Built to withstand tough conditions, the testo 350 is a durable and user-friendly exhaust gas analyser engineered to meet the highest standards for precise industrial emission measurements and comprehensive data management.
     
    Ideal for professional exhaust gas analysis and industrial emission measurements. The testo 350 exhaust gas analyser is a rugged piece of kit designed to meet the demands of a variety of different measuring and analysis applications. It is also excellently suited for complex data compilation.

    The testo 350 is made up of two separate units

    1. Control Unit 
    • The testo 350 Control Unit simplifies emission measurements with a user-friendly graphic display and four distinct application modes: burner, gas turbine, motors, and user-defined settings.
    • Guided on-screen instructions streamline setup and reduce start time.
    • The Control Unit can also remotely manage the Analysis Box, making it especially useful for larger systems where access to the exhaust pipe or measurement site is limited.
    2. Analysis Box (sold separately)
    • The testo 350 Analysis Box houses the sensors and electronics needed for precise emission measurements. It comes with a standard Oâ‚‚ gas sensor and can accommodate up to six sensors, including options for CO, COâ‚‚, NO, NOâ‚‚, SOâ‚‚, Hâ‚‚S, and CxHy.
    • Its automatic extended measurement range enables reliable readings even with high gas concentrations, activating a dilution function to handle unexpected spikes.
    The increasedmeasuring range allows you to carry out unlimited measurements even when gas concentrations are high. The increased measuring range (thinning) is automatically activated when gas concentrations are unexpectedly high. The measuring range of a selected sensor can be increased by a certain factor. An opening on the underside of the analyser gives you access to all the relevant service and wearing parts, i.e. pumps and filters, which can easily be cleaned or replaced.  The testo 350 also has numerous diagnosis functions with easy-to-understand readings and information. The exhaust gas analyser constantly displays the current reading.
    The Analysis Box can be controlled by the Control Unit. It can, however, also be operated directly via USB, Bluetooth® 2.0 or CANCase from a PC or notebook. After the Analysis Box has been programmed, it can carry out measurements independently and save the results. It can also transfer the data directly to the Control Unit.

      • 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.

      Service measurement on industrial engines

      The flue (exhaust) gas analyzer testo 350 is an important tool for adjusting a gas or diesel engine to optimum effect. The testo 350 is used, for example, during commissioning, at regular maintenance intervals, or for troubleshooting unstable operational processes. Exhaust gas measurement is necessary to adjust the engine to optimum operating parameters while complying with the limit value regulations in force - this often entails measurements being taken over several hours. In particular, the high and fluctuating proportion of NO2 in the engine exhaust gas makes the separate measurement of NO and NO2 necessary to provide a highly accurate indication of the real NOx value of the engine. The integrated gas preparation and the special exhaust gas probe for industrial engines with patented special hose provide protection against NO2 and SO2 absorption and allow measured values to be compared, irrespective of date and ambient conditions.

      Service measurement on after treatment systems

      Restrictive limit values necessitate the use of a portable flue/exhaust gas analyzer to reliably determine the exhaust gas parameters in front of and after the after treatment system. In addition to the regular inspections for mechanical damage and contamination, the flue gas measurement provides information about the efficiency and functional reliability of a system. The bus function of the flue gas analyzer testo 350 allows flue/exhaust gas to be measured simultaneously in front of and after an exhaust after treatment system; this enables fast and easy assessment of the system. Any system modifications can be obtained from the measurement protocol.

      Analysis of the gas atmosphere (thermal processes)

      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.

      Service 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.

      Official emissions measurement (compliance testing)

      In most countries, operation of all types of industrial plants (e.g. large power stations, steelworks. cement works, glass works, and chemical plants), and local authority facilities, right through to small production sites is subject to strict regulations governing exhaust gas emissions into the atmosphere. Suitable measures are be taken to ensure and regularly verify that the components defined as pollutants do not exceed certain limit values in the flue gas.

      The flue gas analyzer testo 350 can be used to carry out a preliminary analysis before an official emissions reading, or, depending on the country and directive, the actual official compliance testing.
