| 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 |
