• Operation safety-- Equipped with various intelligent sensors which give sound and light alert to ensure safe operation.
• Performance reliabilitythe instrument adopts components of global renowned brands, to ensure stable and reliable performance.

Space saving

• The width of the instrument is only 1/3 of the traditional six-cell instrument, saving space for a laboratory.

Powerful functions

• Professional test mode provides flexible and diverse control options to meet various needs of scientific research.
• The system provides oxygen transmission rate curve, oxygen transmission coefficient curve, temperature curve, and humidity curve.
• Ultra-wide test range to meet the barrier test of various materials (customize).
• Ultra-wide temperature range to meet the barrier test under different extreme temperatures (optional).

Test Principle

The pre-conditioned specimen is clamped in the test cell, nitrogen with stable relative humidity flows on one side of the specimen while a stream of dry nitrogen flows on the other side. Due to the humidity difference, water vapor permeates through the specimen from the high humidity side into the low humidity side, and is carried to the infrared sensor by the dry nitrogen flow. By analyzing the electrical signals generated by the water vapor, the sensor calculates the water vapor concentration and the water vapor transmission rate.
