Testo, 0563 1512, Digital Differential Pressure Measuring Instrument with App Connection0563 1512 Includes Only:testo 512-1 - Differential pressure measuring instrument with App connection, measuring range 0 to 200 hPa, audible alarmTransport bagConnection hose made of siliconeCalibration protocol3 x AA batteriesFeatures:Simple, fast and precise differential pressure measurement (0 to 200 hPa) for checking filters and for Pitot tube measurement in the ventilation ductReliable measurement results due to position-independent differential pressure sensor with high accuracyFast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart AppVolume flow calculation in measuring instrument and AppWith the compact differential pressure measuring nstrument testo 512-1 (0 to 200 hPa) you have the ideal solution for simple, fast and precise measurement of gas flow and static gas pressure on heating systems, for checking filters on air conditioning systems and for Pitot tube measurement in ventilation ducts. The testo Smart App supports you with useful functions such as configuration, display (also as second screen) and storage as well as documentation of the measured values directly in the App.Differential pressure measurement fast, easy and precise: This is what the compact measuring instrument testo 512-1, which measures pressures up to 200 hPa, is all about. In practical use, it convinces with its flexibility and variety of applications. Checking the gas pressure on burners by measuring gas flow pressure and static gas pressure is just as quick and precise as checking filters and Pitot tube measurement in the ventilation duct. The position-independent differential pressure sensor ensures reliable and highly accurate measurement results. The testo Smart App for smartphones and tablets supports you with these functions:Configure measuring instrumentDisplay graphical measured value curveSave measurement dataManage customers and measuring sitesDocumentation on siteE-mail dispatch of the report.
