Testo 512 Pressure Measuring Instrument: Pressure Range 0–20 hPa, Velocity Range 5–55 m/s, Accuracy 0.5% FS

The Testo 512 is a reliable and versatile pressure measuring instrument, designed for differential pressure monitoring and high-speed air flow measurements. It is perfect for filter checks in HVAC systems and for Pitot static tube measurements in air ducts with fast-moving or contaminated air streams. This rugged, compact instrument displays both pressure and air velocity simultaneously, with the flexibility to switch between multiple units of measurement.

Key Features:

• Simultaneous Display:
  • Measure and display differential pressure and air flow speed at the same time.
• Pitot Static Tube Compatibility:
  • Perform precise air velocity measurements in air ducts with high flow speeds (5 to 55 m/s).
  • Pitot tubes are available separately in different models to suit various applications.
• Density Compensation:
  • Integrated density compensation ensures accurate readings, even under varying conditions.
• Adjustable Damper:
  • Program the damper to smooth fluctuations and average the results for better precision.
• Multiple Units:
  • Choose between m/s and fpm for air velocity and from eight units for pressure:
    • hPa, Pa, mmH₂O, inH₂O, inHg, mmHg, kPa, psi.
• Compact and Durable Design:
  • Built for field use, it is rugged and easy to carry for HVAC technicians.
