Gurley Type Air Permeability Tester
1 - 10,000 Per Unit
1 Unit (MOQ)
CHARACTERISTICS : · Automated Gurley Original instrument. · Easy operation and high measurement accuracy. · Graduated cylinder of 20 oz. and a measurement diameter of 1 inch². · Pneumatic elevation of the inner cylinder. · Full colour 4 ¨ Touch Screen, from which the total control of the instrument can be managed. · Full statistics : maximum and minimum values, mean value and standard deviation. · USB connection for printer. · CE mark. SPECIFICATIONS : This is the more traditional and popular instrument for measuring the porosity and air permeability in materials with intermediate values. May also be tested materials of lower air permeability, using smaller diameter hole measuring plates. The air pressure is produced by an inner cylinder of specific diameter and standardized weight, floating freely in an outer cylinder partly filled with oil serving as air sealing. The sample of the test material is held by clamping plates having a circular orifice of 1.0 square inch (standard) or 0.1 or 0.25 square inches (optional). Porosimeter readings can be evaluated directly or indirectly depending on the material and the objectives of the test. Directly when the capacity of resistance to airflow through a material is tested. Indirectly, when it is wanted to measure other physical properties that affect the passage of air through a porous sheet. APPLICATIONS : · In papermaking and printing, to select materials that provide a suitable degree of ink absorption. · For determining the air resistance of insulating materials. SUPPLY : The standard model includes a 20 ounces cylinder and a lower clamping plate of 1.0 square inch of air hole and an upper adapter. The 20 ounces cylinder is graduated in 25 cc for the initial two spaces and 50 cc for each of the other spaces, up to a total of 300 cc.
Martindale Abrasion Tester
50,000 - 75,000 Per Pcs
1 piece (MOQ)
Abrading instrument, consisting of a horizontal turntable with a center clamp, which revolves at 70 to 75 rpm, upon which the specimen is attached, and two weighte parallel arms, each carrying a special abrasive embedded rubber whell, freely rotating on a ball-bearing horizontal spindle, and each resting on the specimen with a known dead weight load and an adjustable vacuum system for debris removal. For the dry paperboard test, 1000 gf or 500 gf is used with non resilient wheel. For the dry paper test, 500 gf or 250 gf is used with resilient wheels. For the wet test, 500 gf is used the same wheels as used in the dry tests. In all cases, the type and grit of wheels shall be agreed upon by user and supplier. The surface of the table is covered with a disk of soft rubberized material 0.762 mm (0.03 in.) thick each abrasive wheel is 44 to 51 mm (1 ¾ to 2 in). in diameter and 12.7 mm (1/2 in) thick and composed of a special finely screened and standardized abrasive. A revolution counter is attached to the table. The lines of contact of the wheels on the specimen are at right angles to the parallel supporting arms and situated 25 mm (1 in) from the center of the turntable towards the axis about which the supporting arms turn. The center of the line of contact of the wheel on the arm from which the turntable revolves is 31 mm (1 7/22 in) to the left. In this manner, where in contact with the turning specimen, the two wheels revolve in opposite directions and exert a combined abrasive, compressive, and twisting action over a circular path approximately 3000 mm2 (4.6 in2) in area, twice during each revolution of the specimen. 4.1.1 for the wet abrasion test, a rubber-covered turntable with an annular raised rim is used, to permit the surface of the specimen to be covered with water during the test.4.2 Brush, soft brush about 12-13 mm (1/2 in) wide the bristles about 25 mm (1 in) long. Filter paper, sintered glass or Gooch cruicible, for wet abrasion residue. Resurfacing turntable, a rubber covered turnatable on which an abrasive disk is mounted, for resurfacing the wheels.

Taber Stiffness Tester
135,000 - 245,000 Per Piece
1 PCS (MOQ)
The company has cemented its presence among the reputed Manufacturers, Suppliers and Exporters of Taber Stiffness Tester. Our Stiffness Tester evaluates stiffness and resilient qualities of different materials like paper, plastics, cardboard, light metallic sheets, foil and other flexible material. Buyers can obtain these at market-leading rates from us. Details : The instruments is designed for evaluating stiffness and resilient qualities of paper, plastics, cardboard, light metallic sheets, foil and other flexible material having comparatively strong bending resistance. The 38 mm wide specimen clamped between a vice on a balanced pendulum supported by antifriction bearing and lower end clamp on a rotating disc then specimen is bent by 15 degree at a constant speed. When it becomes 50 mm in load length, bending moment required to bent specimen is measured in gcm unit and the stiffness of the material is determined rotation are clockwise and counter clockwise, so that stiffness can be measured in both the directions. Measuring range - 0-5000 Stiffness Units Model AI 3015
