Designed according to ASTM F1249 standard.

Long service life, non consumable.

Equipped with over limit alarm and automatic protection function.

The new rainbow bridge test chamber adopts 360 ° airflow circulation constant temperature technology for better temperature stability.

Test the high-precision humidity sensor inside the chamber, monitor and record humidity changes in real time.

During the testing process, automatic control of flow rate, temperature, and relative humidity is achieved with higher accuracy.

Efficient six chamber design, independent six sets of 50cm2 standard area testing chambers, which is three times the number of testing chambers for traditional moisture permeability detection instruments.

Support simultaneous testing of 6 samples under the same conditions, with independent data.

Within the same testing cycle, the number of completed samples has increased from 2 to 6.

Automatic clamping of samples saves time and effort, with consistent clamping force and better sealing.

Using a 12 inch touch tablet with Windows system for more convenient operation.

Automatic mode, input test temperature and humidity, one click start, fully automatic testing.

Intelligent compartment lid automatically opens and closes, with sound and light reminders.

Embedded Labthink industrial computer to prevent system failures caused by computer viruses and ensure operational reliability and data storage security.

C306H Plastic Film Moisture Permeability Tester - Infrared Water Vapor Transmittance TesterTesting principle:

Clamp the pre processed sample between the testing chambers, and flow nitrogen gas with stable relative humidity on one side of the film, while dry nitrogen gas flows on the other side of the film; Due to the difference in humidity, water vapor will diffuse through the film from the high humidity side to the low humidity side; On the low humidity side, the transmitted water vapor is carried by the flowing dry nitrogen gas to the infrared moisture sensor. Different concentrations of water vapor produce different light signals, and the concentration values are analyzed and calculated to calculate the water vapor transmission rate of the sample.

Reference standard:

ASTM F1249、ISO 15106-2、GB/T 26253、JIS K7129、YBB00092003-2015
