Compensation for the Effects of Ambient Conditions on the Calibration of Multi-Capillary Pressure Drop Standards

Compensation for the Effects of Ambient Conditions on the Calibration of Multi-Capillary Pressure Drop Standards

Cigarette draw resistance and filter pressure drop (PD) are both major physical parameters for the tobacco industry. Therefore these parameters must be measured reliably. For these measurements, specific equipment calibrated with PD transfer standards is used. Each transfer standard must have a know...
