ABSTRACT
High precision headspace resistance standards (HRS) were developed at SRRC for the Micromat model of the fineness and maturity tester (FMT). HRS are stable, physical standards used to create precise differential pressures when air is drawn through the device. Micromat calibration PL and PH air flow rates are "transferred" to the HRS. Routine analysis of 36 cottons from Stonveille, MS is presented based on the transferred calibration. Elimination of short-term drift is demonstrated and confirms earlier work.
