It is suitable for measuring the static friction coefficient, dynamic friction coefficient and peel strength of plastic films, composite films, aluminum foils, aluminized films, plates, rubber, ceramics and other materials when sliding.        

W401L Infrared Water Vapor Transmission Rate Tester High Precision WVTR Testing Instrument for Packaging & Barrier Materials Product Introduction W401L Infrared Water Vapor Transmission Rate Tester is an upgraded high-end precision testing instrument developed by GBPI R&D team in accordance with ASTM, GB and international standards. It measures water vapor transmission rate of samples under controlled temperature and humidity, widely used for films, sheets, paper, packages and materials in food, pharmaceutical, medical devices, daily chemical, photovoltaic and electronics industries. Get a Free Quote Today   Test Principle W401L adopts the infrared sensor testing principle. The pre-processed sample is fixed in the test chamber, dividing it into wet and dry sides. Compressed air flows in the wet chamber, and dry nitrogen (carrier gas) flows in the dry chamber at a fixed rate. Due to humidity gradient, water vapor permeates to the dry chamber and is carried to the infrared sensor. The WVTR value is calculated by the electrical signal output from the sensor.   Compliant Standards ISO 15106-2 ISO 21760-1 ASTM F1249 GB/T 26253 JIS K7129-2 Chinese Pharmacopoeia 4010 YBB 00092003   Technical Specifications Item Value Test Range 0.01~200 g/(m²·24h) Resolution 0.0001 g/(m²·24h) Temperature Range 15~45℃ Temperature Accuracy ±0.2℃ Humidity Range 5~90%RH, 100%RH Humidity Accuracy ±2%RH Test Area 50.24 cm² Sample Size Φ100 mm Test Chambers 1 channel   Key Features Patented high-precision infrared moisture sensor with ultra-high stability and 0.0001 g/(m²·24h) resolution.

Medical Mask Exhalation Valve Air Tightness Tester  is Used to detect the air tightness of the mask breath valve. GBPI offers mask testing machines for surgical face masks, N95 masks, Melt-blown fabric. BFE Tester, PFE Tester, N95 Tester, Melt-blown fabric Tester      

Accelerated weathering tests are performed on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain results on material weathering resistance. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climates. By reproducing these conditions, it can be combined into a cycle and allowed to automatically complete the cycle as required.

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.

The thickness of the film material, an important characteristic of the packaging material, varies and is critical for other properties such as permeability, tensile strength, impact resistance, 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.
