Differential Pressure Measurement devices and gauges

Differential Pressure Measurement Devices are a compact tool designed primarily for heating installers and air conditioning engineers, providing precise measurements of differential pressure up to 0.1 bar. With an optional Pitot tube, the device can also perform flow measurements in ventilation ducts. It supports a range of units for versatile use and is equipped with a silicone connection hose. It features an easy-to-operate design, an illuminated display for low light conditions, and magnets for hands-free operation. Despite its advanced functionalities, the device is straightforward to use and can be securely stowed away when not in use. It also has versions available that allow for connectable probes.


Application Features:


  • Broad Measurement Range: The device measures differential pressure ranging up to 0.1 bar.
  • Optional Flow Measurement: With an optional Pitot tube, the device can perform flow measurements in ventilation ducts, ranging from 10 to 100 m/s.
  • Hands-Free Operation: The device comes with magnets on the rear, allowing users to work hands-free.
  • Multiple Units: It offers a choice of 10 units, including Pa, hPa, mbar, mmH2O, mmHg, inH2O, inHg, psi, m/s, and fpm.
  • Practical and Precise: The device ensures precise measurements with temperature and air density compensation. It’s also small, handy, and easy to operate with just three buttons.
  • Illuminated Display: The illuminated display makes it easy to work in poor visibility or dark surroundings.
  • Secure and Portable: The device includes a belt pouch and plug-on protective cap for secure storage. It also comes with a wrist strap to secure it during measurement.
  • Ready to Go: The included silicone connection hose allows users to start their measurements right away.
  • Versatile Application: The device can be used to measure differential pressure on gas hot water heaters or on filters of air conditioning systems. It can also measure static gas and gas flow pressure on heating systems.
  • Additional Probe Options: The device is also available in versions that allow for connectable probes, providing greater flexibility in measurements.
