Micromanometer [5815]
The DP-Calc™ Micromanometer 5825 allows you to easily make HVAC pressure measurements. This robust instruments can be used with pitot probes to measure duct velocity. The DP-Calc 5825 is a simple to operate, hand held digital micromanometer for fast, accurate differential and static pressure measurements.
FEATURES AND BENEFITS

- Calculate and display velocity when using a Pitot tube
- Variable time constant
- Statistics
- Data logging with time and date stamp
- Stores 12,700+ samples and 100 test IDs
- Programmable K factors
