TSI 5815 DP-CALC Micromanometer

TSI 5815 DP-CALC Micromanometer

The 5815 DP-Calc™ Micromanometer allows you to easily make HVAC pressure measurements. This robust instruments can be used with pitot probes to measure duct velocity. The 5815 is a simple to operate, hand held digital micromanometer for fast, accurate differential and static pressure measurements.


  • Measure differential and static pressure from -15 to +15 in. H2O (-3735 to +3735 Pa)
  • Calculate and display velocity when using a Pitot tube


  • HVAC commissioning and troubleshooting
  • Testing and balancing
  • Pitot tube duct traverses
  • Static pressure measurements
  • Pressure drop across filters, coils, fans, and diffusers
  • Environmental air flow testing
