PORTABLE 12/24 VDC AIR SAMPLER MODEL H-809C
RADēCO Air Flow Calibrators are the most durable and repeatable calibration devices available. The RADēCO calibrators are constructed of a precision machined aluminum venturi tube. The C-Series (analog) employs an appropriately ranged magnehelic gauge while the D-Series uses an appropriately ranged intelligent digital meter, both mounted in rugged steel cases. Simple, cost effective and consistently accurate year after year.
