Item # 4250N GENUINE GURLEYTM H-P-S Tester

QUOTE

The No. 4250 was originally developed to test the printing quality of paper. In more recent years, its use has spread to other industries in testing or checking other material surfaces for smoothness or porosity. In dealing with the printability of paper, it has been found that smoothness is the most important factor in printing quality.

The Gurley No. 4250 H-P-S Tester measures a given air flow through the sample for porosity tests and leakage across its surface(s) for smoothness tests. This is accomplished by changing a variety of adapter and clamping plates.

This model is identical to the No. 4150 and 4240 for porosity tests and their components. Additionally, it includes a 0.34 lb. weight, smoothness test clamping plate, punch and accessory storage box. Both the automatic digital timer and instrument base are recommended and should be ordered separately.
