Reliable and versatile, this commercial/industrial flue gas analyzer kit features a 5" (12.7 cm) HD touchscreen, a standby mode with quick reactivation, and automated on-site reporting via Wi-Fi connectivity. In addition, this analyzer kit includes an NO sensor and a printer.
Designed for construction sites and contractors with high expectations, this combustion gas analyzer automatically displays all measurements on the screen and can be started and stopped simultaneously.
When using the Smart App and the split-screen feature, you can keep a constant eye on all relevant measurement data, even over long distances between the measuring instrument and the burner control unit. Reports can be created on-site and sent directly via the analyzer and its integration with the Smart App. In addition, you can easily retrieve the measurements stored on your analyzer and transfer them to your internal software (via the previously programmed interface) using the new QR code feature.

Intuitive measurement menus with fast response times
This next-generation combustion gas analyzer makes measuring combustion gases incredibly easy thanks to its intuitive operation. The smart touchscreen responds instantly, with no delay. The interactive operation is as simple as using your smartphone.
Convenient second-screen functionality and easy integration of data into user-specific software
Thanks to the practical second-screen feature and integration with the Smart App, you can maintain a constant overview of all relevant measurement data, even over long distances between the measuring instrument and the burner control, saving time and avoiding unnecessary trips. Integrating data from all readings into your software is easy:
Why make measurements complicated when you can keep them simple?
The daily work routine is becoming increasingly demanding. Time is becoming increasingly scarce, while processes are becoming more and more complex. On the other hand, some things unfortunately never change: Using and documenting instruments is complex and time-consuming. But that doesn’t have to be the case this time! Efficient wireless measurement of up to four additional parameters in parallel using smart probes—all thanks to the new, next-generation combustion gas analyzer! Featuring a convenient second screen and intuitive operation, combustion analysis couldn’t be easier.
Applications
Smart measuring technology is of little benefit if it does not keep going in tough day-to-day working conditions. The Smart touch software is a partner that supports you every day in the efficient, problem-free performance of your tasks. Find out why the combustion analyzer is particularly resilient and can easily meet the special challenges across the workshops, transport vehicles and boiler rooms.
