Model W300 Water Vapor Transmission Rate Tester

These Model W300 Water Vapor Transmission Rate Tester has one test chamber,W320 has two test chambers with two separate SENSORS, and W330 has three test chambers with three separate SENSORS and are self standing instruments.
It gives simultaneous test reports, as all the test chambers have separate SENSOR. It measures trace water vapor transmission rates in packaging barrier films.
It ensures the high precision of the testing results with its accurate electromagnetic balance type weighing cell and the circuit handling. It can precisely control the temperature and simulate the humidity.
The dual-testing mode (increasing and decreasing weight methods) is initially adopted.
It represents the ultimate in performance and simplicity of operation. Precision balanced electronics ensure only the highest levels of performance and repeatability available. alibration can be done through balance weight and standard and NIST traceable films for versatility of film to film comparison and reliability of analysis data.
The test result can be seen on the inbuilt LCD screen on the instrument.
