The testo 340 flue gas analyser is a high-performance emissions monitoring tool designed for industrial applications. Equipped with an O₂ sensor, an integrated flow and pressure difference measurement feature, and a calibration protocol, it delivers precise and adaptable flue gas analysis. The ability to add up to four gas sensors makes it suitable for a variety of industrial environments, ensuring reliable performance in high gas concentration conditions.

The testo 350 Analysis Box is an MCERTS-certified, high-performance exhaust gas analyser designed for industrial emissions monitoring in demanding conditions. It supports up to six gas sensors, enabling precise measurements. The Analysis Box can be operated via the testo 350 Control Unit (sold separately), PC software, or remotely via Bluetooth or USB, making it ideal for complex industrial applications. (Able to be fitted with new O2 LongLife sensor).

The testo 350 Control Unit is the perfect companion to the testo 350 Analysis Box (sold separately), providing an intuitive and efficient way to conduct industrial emission measurements. Featuring a robust, industrial-grade design, a large colour display, and internal memory for measurement data storage, it allows for seamless monitoring and data management. The Control Unit can be operated remotely via Bluetooth or a data bus cable, making it ideal for use in challenging industrial environments.

O2 Longlife replacement sensor for flue gas measurement. Exceptionally practical: You can replace the sensor yourself &ndash; the precalibrated sensor is simply plugged into the appropriate flue gas analyser.<br />
<br />
With an extended operational life of up to 4 years&mdash;compared to the standard 2 years&mdash;this upgrade significantly reduces maintenance needs and downtime.
