Detu experts have developed a new portable flue gas analyzer

detu's measurement technology experts have recently developed a new portable flue gas analyzer testo350, whose effective preset function can guide users to conduct professional flue gas analysis smoothly. Compared with the previous flue gas analyzer testo340, testo350 can also measure other parameters such as co2-ir (infrared), CxHy and H2S, and can also be equipped with common gas preparation devices

testo350 enhanced model not only retains the "traditional and global certification" features of the previous series testo350-s/-xl, but also adds the following new functions:

1 Innovative instrument concept

users can preset special menus through the new 3.5-inch color graphical large screen with an operating frequency of 300 Hz and testo350. In addition, the instrument also has built-in functions for a variety of measurement objects, such as burners, steam turbines or industrial engines. After selecting any measurement object, the corresponding typical fuel table and orderly arranged flue gas parameters can be displayed one by one. According to the information on the display screen, users can operate easily without instrument knowledge, thus reducing the work before measurement. User 3. When clamping, try to install the sample parallel to the front and back. You can also observe the process with the help of graphic display, so you can pay close attention to the current measurement and the system

2. Analysis box - the solid design conforms to the industrial standard

the analysis box has gas sensors, air pumps and cleaning pumps, Peltier gas pretreatment (optional), gas circuits, filters, analysis and storage electronic components, power adapters and lithium batteries

the solid shell has built-in anti-collision protection (special structure of X-shaped rubber edge), which well avoids the shutdown caused by instrument pollution. The inherent sealed chamber design comprehensively protects the sensor and instrument electrical from dust, sediment, impact, etc., so that the analysis box can be suitable for harsh environments

the plug-in connection of probe and bus cable can be locked by bayonet assembly to ensure the accurate connection with the analysis box and prevent the measurement error caused by unintentional removal

3. Easy to operate, saving you time and money

testo350 enhanced is equipped with wired and wireless interfaces, which can be directly connected to a computer or printer. Therefore, even if there is a certain distance between the flue to be measured and the equipment calibration site, the measurement data can be easily transmitted, especially suitable for the measurement and calibration of industrial burners

all relevant vulnerable parts that can be easily repaired through the access hole on the back of the instrument can be replaced quickly and easily without using any tools. This means that users can directly clean, maintain and replace components on site to prevent long-term work stoppage caused by instrument maintenance, which can greatly save users' time and cost

testo350 enhanced type is applicable to the flue gas analysis during the commissioning, setting, optimization or work measurement of industrial burners, industrial engines, steam turbines and flue gas purification systems, as well as the control and monitoring of combustion chamber or kiln gas in different processes. In addition, the testo350 enhanced model can also be used to compare the functions of measuring instruments with the same size and range of emission measurement impact test box, and control and monitor the legal emission limit of exhaust gas

testo350 enhanced type in addition to the standard equipped with an O2 sensor, users can directly replace or add five calibrated independent gas sensors on site according to their different measurement requirements, such as CO (hydrogen compensation), low (hydrogen compensation), no, nolow, NO2, SO2, co2-ir (infrared sensor), H2S, HC (combustion sensor), to meet the multiple measurement needs of different users

compared with the atmosphere, the gas in the flue generally has high temperature, high humidity, soot and acid containing components, such as SO2, H2S, HF, HCl and HCN, with high concentration and corrosiveness. Detu's heating sampling system can prevent the formation of acid in the gas sampling probe. However, due to the thick insulation layer in the flue, the recovery of gas sampling will increase by 20% and the items will be reduced by 18%. There is a high temperature difference between the location and the gas sampling hose. The detu heating sampling system can prevent moisture condensation in the gas sampling probe

the concentration of NO2 in the exhaust gas emitted by the engine is usually high and easy to mix with other gases, so it is difficult to accurately measure the actual NOx value of the engine. The gas pretreatment module of testo350 and the polytetrafluoroethylene hose in the flue gas probe effectively prevent the adsorption of NO2 and SO2, so as to achieve high-precision measurement of nitrogen oxides

when measuring unknown equipment or engines with unsatisfactory working conditions, there may be an unexpected high concentration of a measured value (such as CO concentration as high as 50000ppm). In this case, testo350 enhanced can automatically turn on the range expansion function. This not only ensures the longest service life of the sensor, but also ensures that the measurement is not limited

testo350 enhanced type measures volume flow and mass flow for a long time while measuring emissions. The pressure sensor automatically zeros regularly to avoid errors, which can implement reliable and unattended long-term measurement for you. When the instrument is powered on or operated manually, the testo350 enhanced gas sensor can automatically zero through the ambient air within 30 seconds to ensure that the measurement state is entered at the fastest speed
