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.

Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms for indoor air quality, e.g. at draughty windows.

The testo 417 vane anemometer allows you to carry out quick and precise air flow measurements at air inlets and outlets.The easy-to-read display shows air flow speed and direction as well as volumetric flow rate and temperature.The anemometer can also calculate the mean time value, average value and minimum and maximum value at the touch of a key.
