C390M Water Vapor Transmission Rate Test System, is designed and manufactured based on infrared sensor method and conforms to the requirements of ISO 15106-2/ASTM F1249. This instrument can be used to measure the water vapor transmission rate of barrier materials with high, medium and lower moisture barrier properties with a wide testing range and high testing efficiency. The instrument is featured with patented design of integrated block consisting of 3 test cells. Equipped with high precision sensors and professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate properly, which guarantee the testing sensitivity and repeatability of test results. C390M is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, daily chemical, photovoltaic and electronic industries, etc.
The instrument uses Labthink’s new generation water vapor analytical sensor, which is developed by Labthink Global Research & Development Center, collecting top class scientific and technical achievements in Chinese and American sensor technology fields. With core sensor technology, the precision and stability reach world advanced level.
With 30 years’ experience, Labthink has most mature and reliable manufacturing technology of gas permeability testing instruments. Labthink provides customers with high-end barrier property testing instruments with best design, best material, best performance and best sensor by continuously adjusting the details, completing the designs and improving the performance.
By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testing instruments based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method). Labthink has the most complete product line of water vapor permeability testing instruments in packaging industry worldwide.
Labthink is dedicated to providing customers with suitable products. From scientific tracing method to commercially applied method, from scientific research to quality control, you will finally find the products that are suitable for you. C390M Water Vapor Transmission Rate Test System is one of those products.
The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package specimen, the dry nitrogen flow inside the specimen while the outside of specimen is in high humidity environment.
This test instrument conforms to the following standards:
ISO 15106-2, ASTM F1249, GB/T 26253-2010, TAPPI T557, JIS K7129, YBB 00092003-2015
