Wohler 4809 - BlowerCheck

The BlowerCheck BC 21 is a fully automatic, easy-to-use measuring instrument for determining the porosity of buildings and for detecting leaks as per DIN EN 13829 and the requirements of the energy saving ordinance. It provides fundamental results for assessing the quality of a building‘s shell.

In order to offer users the greatest possible support, the device performs the relatively complex measurement sequence required by DIN EN 13829 fully automatically having checked the relevant parameters. Users are guided by means of a large LC display with graphical capability in conjunction with a touch screen for entering data. The large display ensures that all measurement and calculation values can be displayed clearly in a single screen during measurement, so that users always have a good overview of the current status of measurements. The values can then be stored and printed out locally by means of a handy thermal printer using the integrated infra-red interface. It is also possible to transfer the measurements and to perform further evaluation on the PC by means of the Wöhler BC 21 PC software.
