Indoor climate and thermal comfort measurement kit

This measurement set includes the testo 440 dP airflow and IAQ meter. It can be connected to a wide range of digital sensors, testo SmartProbes and many other temperature sensors. In addition to the features of the testo 440, this instrument has an integrated differential pressure sensor. Thanks to it, you can also perform measurements over filters and use Pitot tubes (Prandtl tubes). The instrument has clearly structured measurement menus for duct/vent volume flow, k-factor, turbulence degree, cooling/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.

This is a handy kit for measuring thermal comfort. By measuring the operational (or perceived) temperature, the CO2 content and the degree of draught/turbulence, you can determine whether the indoor climate meets current regulations.

In addition to the instrument, the following parts are included in the measurement kit:

  • Fixed cable pullers
  • CO2 sensor with Bluetooth, incl. temperature and humidity sensor
  • Radiant heat sensor
  • Stand for sensors
  • Combi bag for testo 440 and multiple sensors
