The testo 340 emissions analyser delivers accurate and flexible measurements for industrial combustion and power generation. Its compact design, four-sensor capability, and versatile probe interfaces make it a highly adaptable solution for diverse applications.
testo Probes: testo 340 probes are engineered for reliable, accurate measurements in challenging conditions, including aggressive condensate, high dust concentrations, and extreme temperatures.
easyEmission software: can be used to read, edit, archive and manage measurement data from the testo 340.
Customisable Gas Sensors: Supports up to four configurable gas sensors for flexible and on-site replacements.
Intergrated condensate trap: eliminates any condensate build-up in the actual gas sensor. The testo 340 notifies you when the condensate trap needs to be emptied.
Large fuel selection: with 18 standard fuels and 10 other, freely definable fuels for adapting to suit all applications.

Still need help determining the best solution?
Essential factors for selecting an industrial emissions analyser include quality, precision, and reliability. The chosen device must be tailored to specific industrial processes, emission control objectives, and regulatory compliance. Key considerations for investment are:
Comprehensive measurement parameters
Testo flue gas measuring instruments cover a wide range of measurement parameters, including carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOX), sulphur dioxide (SO2) and more. Our appliances are designed to meet the specific requirements of a wide range of industries.
Highest accuracy and precision
Testo use advanced measurement technologies to deliver precise and reliable results. Our flue gas measuring instruments provides you with certainty that your measurements are accurate and dependable.
Extended measuring range and high sensitivity
The versatility and flexibility of our instruments is demonstrated by their high sensitivity at low concentrations. Additionally, the optional measuring range extension allows accurate measurements even at high gas concentration levels.
Robustness for demanding environments
Testo flue gas measuring instruments are engineered for durability, ensuring reliable performance even in harsh industrial environments. They withstand high temperatures, moisture, and dust without compromising accuracy or functionality.
Automatic data acquisition
Our modern flue gas measuring instruments offer automated functions for data acquisition and logging. This enables efficient monitoring of your emissions and facilitates compliance with environmental regulations.
Easy maintenance and calibration
Testo instruments are designed for easy maintenance and calibration. This ensures long-term accuracy of the measurements and minimises downtimes.
Customer Testimonials: Testo Emission Analysers
"The testo 340 is an excellent piece of equipment. Both tester and printer and user friendly with simple instructions for each step. All components are robust and well designed for use in challenging workspaces. The suitcase is also well designed to ensure the equipment is safely transportable."
Engineering Manager
Balfour Beatty Rail
What we like about the testo 340 is that it is very easy to use. It does not require any additional fixtures to attach it to exhaust tanks or the emission source we want to measure. Not to mention, it doesn't require much maintenance – it's really convenient.
Shirantha Perera
Project Engineer bei Cummins Inc.
Thanks to its high accuracy and reliability, the testo 350 has established itself as the ideal measuring device for us. It ensures that our engines run lean and, above all, very gentle on the material. Personally, I think it's very good that you have an overview of the sensors on the testo 350. I can use a traffic light system to see how the wear of the measuring cells is developing. This leaves sufficient response time to have the device calibrated in-house or to replace measuring cells.
Alexander Vollmer
Training Manager at 2G Energy AG
In my opinion, the testo 350 is the ideal exhaust gas analyzer for the maintenance of marine diesel engines. It is compact and easy to transport, yet provides stable readings that are accepted by the classification societies. And at a very good price-performance ratio.
