Electronic wind pressure gauge
HMG 01 a very accurate pressure measuring device with digital display with 1 mm WS resolution
Well suited for all wind pressure measurements on organs, as it can be used quickly and is also informative in the event of wind pressure fluctuations.

Technical information on the so-called zero point
The above device is a differential pressure gauge. The absolute pressure, which is influenced by the altitude above sea level or the weather, therefore has no effect on the measurement result, provided that the device was adjusted to the zero point before the measurement. It should be noted that the device should not be used shortly after a change in strongly fluctuating ambient temperatures, as the measuring element would otherwise be influenced by the temperature still prevailing in the device. Please allow the device to acclimatize for some time before taking a measurement. We hope that this background information will answer some of your questions.
Differing readings of 1 - 3 mm WS are often due to the bellows system and should not be a cause for concern. Manual devices cannot measure these deviations due to inertia.
Digital pressure gauge - the cheaper alternative
As this measuring device is a universal pressure gauge for various media, it must be calibrated before measuring. It must be set accordingly before the measuring process. The measurement is made in millibars (mbar). 1 millibar corresponds to 10 mm water column. The display resolution is in 0.1 mbar and therefore 1 mm water column. We also supply this alternative electronic wind pressure measuring device with our tried and tested measuring hose with measuring tube and in a padded measuring case. Supplied without 9 V block battery.
