It is suitable for the water vapor transmission rate testing of packaging materials such as plastic films, composite films, sheets, plastic bottles and plastic bags.

Distilled water is placed in the test cup, and then the pre-treated sample is clamped on the test cup. The test cup is placed in the test chamber. Water vapor enters the dry side through the sample, and the water vapor transmission rate of the sample is calculated by measuring the change in the overall weight of the test cup over time.

1.High-precision imported sensors are used to collect data in real time. The test chambers conduct independent tests, ensuring accurate and reliable data.

2.The sensors have an over-range prompt function.

3.The temperature system adopts the PID control method, featuring excellent performance and precise temperature control.

4.The dehumidification chamber is designed to ensure the stability of the humidity of the test sample.

5.It is easy to operate and has an anti-error function for parameter settings.

6.The software interface displays the status of temperature, humidity, weight and transmittance curves in real time.

7.The software interface supports the dynamic display of data and the dynamic scaling of curves.

8.The experimental report is automatically saved and can be exported with one click, supporting the Word and PDF formats.

9.The entire process of the test system is automatically monitored.
