Ideal for official emission measurement (compliance testing): the heated industrial probe kit comprises a heated probe shaft up to 600°C flue gas temperature, a heated gas sampling hose (length 4 m) and a thermocouple type K – this means you are ideally equipped.

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).

This upgrade sensor enables SO<sub>2</sub> low measurement in the flue gas and activates the measurement parameter in the flue gas analyzer.
