This hood model is popular with contractors and facilities personnel because of its versatility, lightweight construction, and ability to document and store readings. A sturdy middle handle allows you to comfortably hold the Balometer hood with one hand. The removable digital meter can be used with optional accessory probes to measure velocity, temperature, and relative humidity.
