sc76 sc76  

The SC76 Differential Pressure Sensor can monitor the differential pressure between two air spaces. The two nipple fittings on the case can be connected to airspaces using the included tubing, allowing the sensor to measure differential pressure between the two sources. Differential pressure requirements are typically found in hospital clean rooms, operating rooms, and construction areas. Air handlers, filtration systems and other pitot tube sensors also require differential pressure measurements.


What's Included:

  • SC76 Differential Pressure Sensor
  • 2 AAA batteries (installed)
  • 2' (0.7m) of extra rubber tubing (5/32" OD)


  • Measures ±1 psi (±6.9 kPa) differential pressure
  • Low power design - Battery powered sensor provides installation location flexibility
  • Long battery life expectancy – 7-10 years
  • Compact size convenient for easy installation
  • Industry leading data storage – up to 120 Billion points
  • Powerful DataRecorder software included to chart, log, monitor all individual sensors
  • HaloCloud service for access to remote sensor data and configuration from anywhere including from Tablets, Smart Phones, Remote PCs
  • Programmable individual sensor alarm set points and alarm notification via email or Text message with HaloCloud service
  • Complete setup requires one System Gateway (GWx series). Add sensors as needed with scalable system and gateways capable of handling hundreds of sensors at a single location
  • Compliant to RoHS Directive 2002/95/EC
