Accurate and reliable data

With The State Certificate for Gradation of the certified Reference Materials and Licence for Manufacturing Measuring Instruments of the state Reference Materials(GBW(E)130543/4)of Water Vapor Permeability Analyzer approved and issued by General Administration of Quality Supervision, Inspection and Quarantine of the P.R.C. Adopting state reference materials to calibrate and verify the instruments, data reliability up to 100%, with universal temperature and humidity calibration interface and test repeatedly, the dispersion of the same sample test data are less than 10%. Ensure the accuracy, universality and authority of the test data.

Simple operation

(1)Professional software with simple interface, easy to use and convenient to set test process.

(2)Computer automatically monitors the whole test procedure: auto test, auto judgment, and auto stop.

(3)Curves display of transmission, water vapor concentration, temperature and humidity in real time. The curves with conceal function, support query function for background data.

(4)Professional test report; can export file in PDF format.

Advanced technology

(1)Temperature control: International advanced electromagnetic technology, program controlled, auto heating and cooling; no need of external accessories. Precision: 0.1℃.

(2)Humidity control: Dual gas flow method(dry gas and humid gas), high precision (2%RH) and stable flow.

(3)Mainframe configures with color touch screen, can observe temperature, humidity and transmission and can run independently without external computer.

(4)Introduce multiple foreign advanced technologies, precision is as high as 0.001 g/m2·24h.

High efficiency

(1)Three chambers work independently with gravimetric method, each chamber has separate report; can run one chamber or two chambers or three chambers respectively.

(2)High precision sensor, continuous weighing and data acquisition, so test data is reliable.

(3)By adding adaptive accessory, can test water vapor transmission of various containers such as bag, bottle, can and bowl.

(4)Can be expanded up to 10 chamhers.

(5)The only water vapor permeability analyzer with cup method that can test aluminum foil, aluminum laminated films and other high barriers materials in the industry.

Calibration & Certification

(1)The instrument supports two methods of reference materials and standard gas to calibrate and certificate; operation is simple, user only need use certified reference materials for normal testing, and then input the test result into the instrument interface.

Reliable and easy-maintenance instrument

(1)Adjustment parameters are managed by coded lock. The whole procedure is finished automatically.

(2)Sensor over-range protection, prevent damaging important sensors.

(3)Function modularization, easy to maintain.
