For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow and air temperature.

The hot wire probe (in conjunction with the appropriate measuring instrument) is ideal for determining flow velocity and temperature in ventilation ducts or at plate outlets and ventilation grilles.

Use the vane probe to determine air velocity, volume flow and temperature at air outlets, as well as at plate outlets, ventilation grilles or swirl outlets.

Use the vane probe to determine air velocity, volume flow and temperature at air outlets, as well as at plate outlets, ventilation grilles or swirl outlets. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.

Emission control in industry: the testo 340 flue gas analyzer gives you professional technology, easy handling and practical execution in one instrument. The high-performance testo 340 flue gas analyzer is fitted with an O<sub>2</sub> sensor and can be equipped with up to 3 additional 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. Use it to carry out quick spot measurements at ventilation grilles (air outlets). The anemometer is also ideal for 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 for rapid measurement at ventilation grilles (air outlets) and for inspecting air conditions – also outdoors: use the testo 410-2 vane anemometer to measure humidity, as well as air velocity and air temperature. Dew point and wet bulb temperature, wind chill or Beaufort wind force: the anemometer can accomplish the calculation of all these parameters at the touch of a button.

Kompaktni krilni anemometer testo 417 v kompletu vklj. dva merilna lijaka sta bila razvita, da bi vam čim bolj olajšala meritve na dovodih in izhodih zraka ter ploščatih izhodih klimatskih in prezračevalnih sistemov. Vgrajena 100 mm lopatica hitro zagotovi natančne rezultate. Povprečne vrednosti časa in točk ter volumski pretok se samodejno izračunajo v instrumentu in prikažejo na zaslonu. To omogoča posebej učinkovito prilagajanje uravnoteženih stanovanjskih prezračevalnih sistemov - vključno s hitro dokumentacijo z aplikacijo testo Smart APP. </br>IPoleg tega vas aplikacija ne podpira samo pri konfiguraciji merilnega instrumenta, ampak prevzame tudi prikazovanje, shranjevanje in dokumentiranje izmerjenih vrednosti – vaš pametni telefon spremeni tudi v drugi zaslon. Komplet testo 417 Kit 1 vključuje dva merilna lijaka za izhodne odprtine in prezračevalne rešetke. Te je mogoče preprosto pritrditi na lopatico in pokrivajo širok razpon velikosti in formatov izhodnih odprtin.
