Emission checks in industry are easy with the flue gas analyzer testo 340. Professional technology meets practical design. The testo 340 flue gas analyzer is easy-to-use for emission measurement in industries. It can be fitted with up to four different gas sensors.

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.

The testo 410-1 vane anemometer measures air velocity and air temperature. You can use it to carry out quick spot measurements at ventilation grilles (air outlets). The anemometer is also ideal to use outdoors. It displays the units m/s, km/h, fpm, mph and kts, and also calculates wind chill and the Beaufort wind force.

Ideal anemometer for air velocity measurement at ventilation grilles (air outlets) and for inspecting air conditions – also outdoors. Pocket sized testo 410-2 also measures humidity and air temperature. The anemometer can also accomplish the calculation of parameters such as dew point and wet bulb temperature, wind chill or Beaufort wind force – all at the touch of a button.

Professional measuring technology in a small format: the compact testo 410i vane anemometer with smartphone operation measures the volume flow, air velocity and temperature at air outlets quickly and reliably. The testo Smart App enables readings to be viewed conveniently and offers intelligent additional functions.

Air flow meter with a fixed vane probe – ideal for carrying out air flow measurements in air ducts thanks to the extendable telescope. The volume flow is directly shown in the display. The timed and point mean value calculations provide

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.

The functional testing of ventilation and air conditioning systems includes monitoring the flow speed in ventilation ducts. If the air flow velocity and volumetric flow are not set correctly, the room air quality may suffer. The testo 425 air velocity meter measures the air velocity and automatically calculates the volumetric air flow.
