Industrial emission testing: a combination of professional technology and practical design. The testo 340 is a compact four component flue gas analyzer that is extremely easy to operate.

In September 2018, Detu upgraded the testo 340 flue gas analyzer, which can be equipped with a new anti-interference SO2 sensor to accurately measure SO2 at concentrations of up to 10000ppm carbon monoxide. At the same time, the instrument will be equipped with Chinese version operating firmware and open Bluetooth communication function, bringing more convenience to your daily measurement work.

Portable, sturdy, and with numerous advantages

Measurement tasks can be carried out when the concentration of the gas being measured fluctuates sharply
During the measurement process, if the concentration values of the measured gases (CO, NO, SO2) fluctuate dramatically and exceed the sensor range (or sensor protection limit), the 5-fold range extension function of the CO, COlow, NO, NOlow, and SO2 sensors will automatically activate. The instrument will maintain the measurement and monitor changes in the working conditions of the measuring points, while also reducing the load on the gas sensors.

Built in controllable measuring air pump
The positive/negative pressure of the measuring point is within the range of -200 mbar to+5 mbar, and the sampling air pump can automatically maintain a constant pump flow value.

Built in condensing tank
It can remove water vapor from the sample gas that is about to enter the gas sensor. When it is necessary to clear the condensation tank, testo 340 will automatically issue a prompt.

Pre calibrated sensor
The standard configuration of testo 340 includes an O2 sensor, and users can choose to install three more gas sensors according to their needs. After replacing or upgrading the sensor, it can be measured without calibration.

Numerous fuels to choose from
The instrument is equipped with 18 standard fuels and 10 customizable fuels, suitable for various application fields.

T Ü V inspection/EN standard
O2,CO2,CO,NO,NOlow, The accuracy of parameters such as ℃ and hPa complies with EN 50370 Part 2. Pre calibrated sensors (which can be measured without calibration after replacing or upgrading the sensor) also meet the above standards.
