98-16: The Relationship Between SP and HGBIK Drift Measurement Results - NewThe CTI drift measurement code ATC 140 specifies that isokinetic measurements be employed for cooling tower drift emissions measurements. The sensitive paper techniques, an alternative method also referenced by the test code, provide additional information not supplied by the Isokinetic test procedure. There have been few occasions; over the years when both the Sensitive paper and HGBIK drift measurement techniques have been employed at the same
