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.

  GBL-H2 Electronic Universal Testing Machine High Precision Mechanical Performance Tester Product Introduction GBL-H2 is a universal single-column electronic tensile testing machine developed by GBPI based on GB, ASTM standards and market demands. Equipped with high-precision sensors, it features high accuracy, stable loading and long service life. With LCD display and professional software, it shows real-time test curves and reports. Fully automatic operation with complete safety protections: limit protection, overload protection and emergency stop. Widely used for tensile, peeling, heat sealing, tearing, puncture tests of metal & non-metal materials in food, pharmaceutical, packaging industries, inspection centers and research institutes. Test Principle The prepared sample is fixed between two clamps. Start the instrument to make the clamps move relatively. The force sensor collects force changes, and the displacement sensor collects displacement changes, so as to calculate the tensile, peeling, heat-sealing, tearing and other performance indicators of the sample. Compliance Standards GB 8808 GB 13022 GB/T 1040 ASTM D882 ASTM E4 YBB Series QB/T Series Technical Parameters Item Parameter Force Range 0~300N (Optional 0~500N) Accuracy ±0.5% FS Test Speed 0~500 mm/min Displacement Accuracy ±0.5% Test Width 30mm (50/60mm customizable) Stroke 750mm (1000/1200mm customizable) Dimensions 600×500×1300mm Weight 65kg Power AC 220V 50Hz Product Features Ergonomic Design Desktop column structure, compact and easy to operate.

Product introduction The automatic three-station rotary mode spout sealing machine is specially designed for automatic sleeving and heat sealing of straws and bags. It is suitable for straws of various calibers, lengths and models, and is the preferred automated equipment for spouted stand-up pouches in beverage packaging, drinkable jelly, condiments, and daily chemical products (laundry detergent, skin care products, etc.). It can be customized to connect with filling production lines.

It is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate. The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling, which is suitable for the performance testing of bacterial filtration efficiency of medical surgical masks by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.
