The Testo 512-1 Differential pressure measurement is fast, easy, and precise and measures pressures up to 200 hPa. 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 measurements 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 instrument
• Display graphical measured value curve
• Save measurement data
• Manage customers and measuring sites
• Documentation on site
• E-mail dispatch of the report

Testo 512-1 is a position-independent differential pressure sensor with high accuracy of up to 200 hPa for checking filters and for Pitot tube measurement in the ventilation duct, incl. volume flow calculation in measuring instrument and App.
