The TSI DP-Calc 5815 and 5825 micromanometers allow you to easily make HVAC pressure measurements. TheDP-Calc instruments can be used with Pitot probes to measure duct velocity. The DP-Calc 5815 is a simple to operate, hand held digital Micromanometer for fast, accurate differential and static pressure measurements. The high performance DP-CALC™ 5825 can calculate flow and has data logging capabilities.

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

Applications
  • 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
