TM
Micromanometers
Models 5815 and 5825
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-C
ALC 5825
can calculate flow and has data logging capabilities.
