Water Vapor Permeability Analyzer W405

Features :

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, ensure the accuracy, universality and authority of the
test data.
Simple operation
· Professional software with simple interface, easy to use and convenient to set
test process.
· Fully-auto operation, one-button test, judge and stop automatically.
· Programmed auto-control, the experiment status display in real time.
· Curves display of transmission, water vapor concentration, temperature and
humidity in real time. The curves with conceal function, support query
function for background data.
· Mainframe configure with color touch screen, can observe temperature,
humidity and transmission without external computer.
· Professional test report; can be exported as PDF.
Advanced technology
· Temperature control: International advanced electromagnetic technology,
program controlled, auto heating and cooling; no need of external
accessories. Precision: 0.1°C.
· Humidity control: Dual gas flow m ethod (dry gas and humid gas), high
precision (1%RH) and stable flow.
· Carrying cutting-edge ARM controlling system, can run independently
without computer.
High efficiency
· Three independent test chambers: With three sensors and each chamber test
independently, three same/different samples can be tested at the same time
and output three test reports, which improve test efficiency.
· With three different test modes of high, medium and lower barriers, can test
films with different barrier property.
· Measurement precise up to 0.001 g/m2·24h, can test high barrier materials,
such as aluminum foil.
· By adding adaptive accessory, can test water vapor transmission of various
containers such as bag, bottle, can and bowl.
Calibration & Certification
· 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
· Imported infrared sensor, with high precise and good performance, can work
for a long time.
· Sensor over-range protection, prevent damaging important sensors.
· Highly modularized, easy to maintain.
