Model 5825
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
Added Features Model 5825
  • Calculates flow
  • Data logging with time and date stamp
  • Stores 12,700+ samples and 100 test IDs
  • Includes LogDat2™ downloading software
  • Programmable K factors

The DP-CALC 5815 and 5825 micromanometers allow you to easily make HVAC pressure measurements. These robust 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.

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
