Datasheet HM28 HUBER INSTRUMENTE AG, Grellingerstrasse 23, CH-4208 Nunningen Differential pressure / absolute pressure Battery or power supply unit Integrated data memory A convincing feature of this handheld pressure gauge is its versatility. Functions are available for leak rate, min./max. values and for storing the measured values in the display. The measured values can be stored in the integrated data memory with the datalogging function and from there, logged directly on a connected printer (without PC) via the RS232 interface. Of course a PC-software level Windows is also available. The HM28 permits measurements in over-and underpressure, differential or absolute pressure.
