PH720
The model PH720 electronic balancing tool is auto-zeroing and is
density corrected for temperature and pressure. Users can power
the unit by AC or with 4 AA-size rechargeable or alkaline batteries.
It comes with a pitot probe and 2 static pressure probes, but it
can be used with available 16-point velocity matrix, air foil, temperature,
or RH/temperature probes. CompuDAT™ PC downloading software
is included.
