With the current firmware, the digital pressure gauge DG 1000 now additionally receives a logger function for long term recording of data. Depending on the selected measurement interval (1 300 seconds), the DG 1000 records pressure differences over a period of 80 days up to several months. In this way, external influences on buildings caused by wind and thermal can be analyzed or building pressure differences generated by a mechanical exhaust air system or a ventilation system with heat recovery can be teste d. Further applications are the measurement of pressure differences of individual ventilators in kitchens or bathrooms, the long term recording of pressure differences in clean rooms or the determination of the flow direction of leakages.
