Comparison Chart Details

This comparison chart shows each generators capabilities, specifications, and uncertainty values to help you determine which suits your calibration needs best.
Note: on the Model 2500, the “ST” model is not shown, the differences in this model are the chamber size which is 15" x 15" x 12" (38.1 cm x 38.1 cm x 30.5 cm) plus on this model you can add a high air flow (HAF) of 10 to 40 Liters per minute.
