All Densometers … WebManual Densometers 4110N. Densometers are the accepted standard for measuring the porosity of materials such as papers, wovens, plastics and membranes. All Densometers measure the time required for a given volume and of air (25cc to 400cc) to flow through a standard area of material being tested under light uniform pressure.
BENDING STIFFNESS TESTER GURLEYTM - Klimatest
WebThe 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. WebAll genuine GurleyTM bending resistance/stiff-ness testers measure the force required to bend a wide variety of materials under con-trolled and repeatable conditions. This force may be equated to stiffness, resilience, flexi-bility or pliability, depending on the nature of the material and purpose of test. There are 15 possible specimen sizes ... javascript filter first item
Gurley High Pressure Manual Densometers Thwing Albert
WebSince 1923, GENUINE GURLEY film, sheet, tubing and paper-testing instruments have been the industry standards for measuring physical characteristics such as stiffness, flexibility, water absorption, softness, porosity, air-permeability and smoothness.Gurley test instruments are used extensively in the paper manufacturing, paperboard converting, … WebIn 1885 Gurley started making Hydrologic equipment and in the early 1900s acquired many new fields including paper testing equipment and thermometers. ... Stiffness. The Gurley unit is a measure of the stiffness of a material. Since the measurement device holds a piece of material vertically and tests the force required to deflect the material ... WebTABER STIFFNESS TESTER - INTERPRETING RESULTS After the test material has been deflected 15° (or 7 ½°) to the left and right, the average reading is determined. This is then multiplied using the number assigned in the Set-Up Chart for the particular range. The product is the stiffness value of the material measured in Taber® Stiffness Units. low power dc to dc converter
