COBB Absorption Tester is for the measurement of surface water absorption of paper and paper board. Loose paper, e.g. newsprint, unsized paper, e.g. blotter and other high absorbability paper is not for this tester. Principle The Cobb value of surface water absorption of paper and paperboard.: The calculated mass of water absorbed in a specified time by a unit area of paper or board under specified pressure and temperature conditions. It is expressed in g/㎡. C=（G2-G1）×100。 C-water absorptiveness G2-wet mass, in grams, of the test piece G1-dry mass, in grams, of the test piece When Cobb value is less than 200～250 g/㎡ for single layer, more layers can used. Technical Data Metal roller sectional area: 100±0.2㎝2 Metal roller diameter: 112.8±0.2mm Roll height：50mm Blotting paper: 200～250g/㎡ Absorption speed: 75mm/10min Smooth metal roller: length 200±0.5mm，mass10±0.5kg。 Water volume: 100mm±5ml。 Dimension: 480×400×420（mm） Weight: 28kg Standard GB/T 1540，QB/T 1668，ISO 535

Torque Tester measures the open force and lock force of the caps of medicine bottles, PET bottles, spout bags and flexible tube packages. The torque test can determine the proper lock and open force of caps in production and thus guide the transportation and consumption process. Features PLC control unit and touch screen operation Both locking and opening force can be measured Peak value auto keeping Micro printer for easy data recording RS232 port and professional computer software (optional) Overload protection, auto zeroing function Technical Data Test Range: 10 Nm Accuracy: 1% FS Resolution: 0.001 Nm Clamp Range: Φ5mm～Φ170mm Dimension: 240×350×270 mm Weight: 19 kg Standards ASTM D 2063, ASTM D3198, ASTM D3474, GB/T17876, BB/T0025, BB/T0034 Standard Configuration: Mainframe, micro printer Optional: software, communication cable

Tensile testers can be used to measure tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture force, opening force and other performance of plastic films, composite materials, soft package materials, plastic flexible tube, adhesives, adhesive tape, label stickers, medical plasters, release paper, protection films, combined caps, aluminum foil, diaphragm, back sheets, non-woven fabrics, rubber, paper, etc. TST-01 Tensile Tester Features 1. 7 inch TFT touch screen makes parameter setting and test operation easy and convenient. 2. PLC programmable logic controller realizes precise control of the driving system and the overall performance of the instrument. 3. Precision ball screw for accurate speed and displacement. 4.

Gradual heat sealer is professionally designed for the precise measurement of five groups of sealing temperature, time and pressure. Gradual heat sealer is for the determination of the heatsealability of a surface, or sealant layer of films, laminates, composites and polymers etc. How well the material heatseals is expressed quantitatively as seal strength as a function of the sealing conditions of temperature, time and pressure. It conforms to standards of ASTM F2029, QB/T 2358 and YBB 00122003. Gradual heat sealer Features 1. Five groups sealing temperature can be measured with one test 2. Proximity and pressure sensor for precise dwell time and sealing pressure control 3. P.I.D. temperature control 4. Uniform heating by aluminum encapsulated sealing jaws 5. Independent heating of upper and lower sealing jaws 6. Sealing jaw customization available Gradient Heat Seal Tester Specification Sealing temperature Room Temperature 250℃ Temperature Gradient ≤20℃ Deviation ±0.2℃ Dwell time 0.1 s990H Sealing pressure 0.15 MPa 0.7 MPa Double Heating Sealing Jaws 40mm×10mm×5(Sealing Surface)(Customization Available) Gas Pressure 0.5 MPa0.7 MPa of Air Dimensions 455mm (L) *320mm (W) *440mm (H) Port Size Ф6 mm PU Hose Gradual heat sealer Standards ASTM F2029, QB/T 2358, YBB 00122003
