The testo 350 is a rugged, easy-to-use exhaust gas analyzer designed to meet the highest demands when it comes to carrying out precise industrial emission measurements and providing proper data administration. The Analysis Box can be operated with up to 6 gas sensors, 5 of which are optional. This allows you to select freely from sensors for CO, NO, NO2, SO2, H2S, CxHy and CO2.

Equip your flue gas analyzer with an additional measurement parameter. This retrofit sensor enables H<sub>2</sub>S measurement in the flue gas and ensures activation of the measurement parameter in the flue gas analyzer. Particularly practical: you can insert the precalibrated sensor into the compatible measuring instrument effortlessly yourself.
