GB-MH180 Respirator Fit Test Machine is a specialized instrument for measuring leakage ratio of dust concentration quantitatively in and out of mask to select fitted mask and check leakage, which is compatible with the requirements of OSHA and GB 19083-2010 .The Respirator Fit Test Machine is widely used in workplaces such as hospitals, manufacturing plants, production sites, and other testing institutions.  

This Series machine can be applied to test lots of materials in rubber tensile elongation, compression, tear, big size peel (can 90 degrees and 180 degrees) and other mid-force mechanical test（ 5KN,10KN,20KN,optional ） , such as tires, belt, shoes, plastic, film, acrylic,FRP, ABS, EVA, PU, aluminum-plastic pipe, composite materials,waterproof materials, fibers, textiles, wire and cable, paper, gold foil,ribbons, thread, spring, wood, medicine packaging materials, tapes etc.

 GBM-D1 intelligent sealing performance tester uses the working principle of pressurizing the sample to test the sealing strength and integrity of packaging materials. It is suitable for food and medicine packaging materials such as flexible, rigid, porous and laminated aluminum foil. There are multiple test modes for comprehensive evaluation of the tightness and integrity of packaging materials. Wide applicability, complete functions and accessories, in line with applicable ASTM, ISO and GB standards. At the same time, our company provides matching accessories and services for different samples.  

             

GBD-L2 falling dart impact tester is suitable for testing materials such as plastic film or sheet and steel plate coating with a thickness of less than 1mm. Under a given height of free falling dart impact, it can measure the energy (in Quality to express results) of plastic films,thin section specimens and other materials. Through the impact resistance test, it can prevent the packaging surface from being damaged when the packaging material is impacted or dropped due to insufficient toughness of the packaging material, and effectively avoid the product from being damaged due to impact or falling in the circulation link. It can be used in scientific research, teaching, industrial and mining enterprises, laboratories, research institutes and quality supervision departments.

ZM-100 Inverted pressure sterilizer boiler is used for sterilization and high temperature test of packaging materials (including adhesives and printing ink) in the industries of packaging, plastic films, food, medical units, inspection agency, research institute etc.

GX-B3 type disc peeling tester is used for testing the adhesion fastness of printing ink layer of plastic film and cellophane decorative printed materials (including composite film printed materials) produced by gravure printing process. It can also be used to test the adhesion state of the surface layer formed by vacuum coating, surface coating, compounding and other related processes.  

Product Brief The N600P Paper & Paperboard Air Permeability Tester is custom-developed to align with standards like GB/T 458-2008 and ISO 5636. It adopts the differential pressure method as its core testing principle, and innovatively integrates three industry-common testing approaches (Gurley, Schopper, and Bendtsen) into a single device.   This tester is applicable to air permeability detection of various paper and paperboard materials, and can measure key indicators including: material air permeability, air resistance, gas transmission rate, and total gas transmission volume. Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas volume. Bendtsen Method   After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the surface of the sample. Executed Standards GB/T 458-2008, SJ/T 10171-2016, ISO 5636-5:2003, ISO 5636-2:1984, ISO 5636-3:2013, TAPPI T460 Technical Parameters   Item Technical Parameters Test Range 0.1~10 μm/(Pa·s) Resolution 0.001 μm/(Pa·s) Differential Pressure Range 0~5 kPa Pressure Resolution 0.001 kPa Test Area 6.42 cm² or 10.0 cm² Sample Size ＞50 mm×50 mm Instrument Dimensions (L×W×H) 450 mm×400 mm×300 mm Power 100 W Power Supply 110~250 VAC, 50~60 Hz

It is suitable for the resistance of the mask to the penetration of synthetic blood under different levels of test pressure. The mask material is tested with synthetic blood under continuously applied pressure, and the penetration of synthetic blood on the material is visually checked.

Full-automatic Total Migration Tester AUTO ZF1800G has an integrated system design of water bath evaporation, heating, drying, cooling, and constant temperature weighing. The testing process is fully automated without manual operation. It is suitable for testing the overrall migration (non-volatile matter, evaporation residue) and other items in the fields of purified water, pharmaceutical packaging materials, food packaging, cigarette tipping paper and chemical reagents. It can also be applied to the water content, loss on drying and other items of solid samples, and the total dissolved solid content test in water quality testing.

Face Mask Flame Retardant Tester is a special test instrument for the flame retardancy of a mask. Mask testing machines for surgical face masks, N95 masks, Melt-blown fabric.    

A substance or material that has been determined to have a sufficiently uniform property value, as a "measuring device" in the analytical measurement industry.
