EBT721 Balometer Capture Hood
|
The EBT721 Balometer Electronic Balancing Tool features a detachable multi-purpose digital manometer that can be used with a variety of common test and balance tools, such as pitot, air foil, temperature, relative humidity probes or a 16-point velocity matrix. It will become the tool of choice for contractors and facilities personnel because of its ergonomic design and extremely light weight.
