F&J - Model DFHV-1S - Digital Flow Meter High Volume (100 - 120 VAC)
Various flow and volume engineering units are available for selection.
The air sampler is mounted on a rigid base with non-skid rubber feet.
The air sampler is supplied with a 4 inch (102 mm) diameter filter holder. Options include an adaptor to convert from a 4 inch diameter opening to a 1.83 inch opening for standard combination filter holders (P/N: HV1SAP).
The DFHV-1S air sampling system is designed for periodic indoor use. Please consult the product specifications for the design temperature range and the installation category.
