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.

That is correct. The DP-Calc 5815 is a handheld digital micromanometer designed for fast and accurate differential and static pressure measurements, while the DP-Calc 5825 is a high-performance version that can also calculate flow and has data logging capabilities. Both models have various applications in HVAC commissioning and troubleshooting, testing and balancing, pitot tube duct traverses, static pressure measurements, pressure drop across filters, coils, fans, and diffusers, as well as environmental air flow testing.

Both models can measure differential and static pressure from -15 to +15 in. H2O (-3735 to +3735 Pa) and display velocity when using a Pitot tube. The DP-Calc 5825 has added features such as variable time constant, statistics, data logging with time and date stamp, stores 12,700+ samples and 100 test IDs, programmable K factors, and includes LogDat2 downloading software.
