Water Vapor Permeability Tester is manufactured based on the gravimetric method, and is applicable to test the water vapor transmission rate of plastic films, composite films, sheets and other materials used in packaging, medical and constructive industry. Features Standard periodic weighing method and auto-zeroing function guarantee the accuracy and uniformity of the testing data. Touch interface is more convenient to operate. The test data is reliable due to the automatic process and the weighing system controlled by the gas cylinder. Innovative circulating dehumidification system with built-in vacuum pump can effectively prevent the formation of humidity gradient and ensure the accuracy. High-precise and automatic control system of temperature can be used under different conditions. The data can be stored and outputted in multi-format (including report in excel and cloud sharing). The rapid calibration mode with standard weight-counter is provided. GMP management of user's three-level authority complies with international standard. The instrument processes statistical analysis of single and group data. Equipped with ISP control online and upgrade function. Specialized communicating software can display in real-time, analyze and store data. Principle Under a certain temperature, the constant difference of humidity is generated between two sides of the test specimen. The water vapor permeates through the specimen and gets into the dry side. By measuring the weighing changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330�ºC. HPMA has obvious threshold effect under high temperature (350�ºC) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300�ºC with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.
