DeltaCal DC1 Calibrator for FRM Samplers


DeltaCal is the first and only continuous volumetric flow calibration/audit device which gives a direct indication of volumetric flow rate, standard flow rate, barometric pressure (both mm/Hg & mb), ambient temperature and filter temperature in one instrument. It was developed for use with U.S. EPA PM2.5 designated samplers and their PM10 derivatives. With an accessory adapter it is usable with any air sampler in the 1.5 to 19.5 Lpm range. The DC100 version has a range of 10-60 Lpm. Typical screens are shown below on the left.
