PASPORT Dual Pressure Sensor - PS-2181


Shown in use with the PASCO Heat Engine/Gas Law Apparatus


The PASPORT Dual Pressure sensor is capable of reading 2 absolute pressures, 1 gauge pressure, or 1 differential pressure. Dynamic variable over-sampling automatically reduces the measurement noise at low sampling rates. Sample rates up to 1000 Hz make studies of both transient and steady- state pressure possible. Includes quick-connect tubing.

Typical Applications

  • Measure pressure in a Heat Engine
  • Measure pressure drops in pipes
  • Measure pressure on both sides of PASCO's Diffusion/Osmosis Apparatus
  • Study gauge and differential pressures


  • Quick-release Connectors (4)
  • Tubing Connectors (4)
  • Polyurethane Tubing (2.4 m)
