pressure meter 510

differential pressure meter incl. protective cap, batteries and calibration certificate

The differential pressure meter is ideally suitable for pressure measurements in the range 0 to 100 hPa. 510's differential pressure measurement is temperature-compensated for accurate readings. Readings can be displayed in Pascal over the whole measurement range. Magnets at the back of the instrument enable hands-free operation, for instance, while adjusting gas heaters.

  • Display in Pascal possible over entire measurement range
  • Accuracy: ±0.03 hPa (0 to 0.30 hPa) / ±0.05 hPa (0.31 to 1.00 hPa)
  • Temperature compensation
  • Magnetic rear permits free-hand work
  • Flow velocity measurement with Pitot tube (Pitot tube not included in delivery)
  • Air density compensation
  • Protective cap for safe storage
  • Including wrist strap and belt holder
  • Backlit display
  • Switchable units: hPa, mbar, Pa mmH2O, mmHg, inH2O, inHg, psi, m/s, fpm

pressure meter 512 - differential pressure meter, incl. battery and calibration document

Model 512 provides simultaneous pressure and flow measurements in one compact, versatile instrument. It offers two user-switchable units of flow: feet per minute (fpm) and meters per second (m/s). Eight different units of pressure can be selected: psi, inches H20, inches Hg, kPa, hPa, Pa, mH20 and mHg. All readings are clearly visible on a large backlit display. The versatile model 512 provides smoothing between 1 and 20 display refreshes (0.5 sec) yielding a sliding mean reading. Density compensation is built-in. A separate HOLD-MIN-MAX button freezes readings and displays both flow and pressure extremes. Optional accessories include the IR printer for on-site documentation of all measurements by date and time, plus the seethrough protective cover for protection against dirt, moisture and impact.

  • Simultaneous display of flow and pressure
  • 8 units for pressure: psi, inH2O, inch HgkPa, hPa, Pa, mm H2O, mmHg
  • 2 units for flow: fpm, m/s
  • Built-in density compensation
  • Backlit display
  • Hold/Max/Min function
  • Readings printout with date/time and min./max. values
