Product catalog summary

Overview
The C406H Oxygen/Water Vapor Transmission Rate Test System is designed for high precision and efficiency in testing the transmission rates of oxygen and water vapor through various materials. It adheres to standards such as ASTM D3985, ASTM F1249, and ISO 15106-2, making it suitable for industries like food, medicine, and electronics.

Product Features

Dual Testing Modes: Offers OTR/WVTR, OTR, and WVTR modes for comprehensive testing.
Coulometric Oxygen Sensor: Provides high sensitivity with a longer lifespan and no calibration needed.
Infrared Moisture Sensor: Patented design with a long service life and automatic protection features.
Accurate Data: Utilizes advanced structural test cells and temperature control for precise measurements.
High Efficiency: Features six independent test cells, allowing simultaneous testing of multiple samples.
Intelligent Operation: Equipped with a 12-inch touch panel and automatic test procedures.
Safety and Reliability: Incorporates high-end industrial computers and intelligent sensors for secure operation.
Space Saving: Compact design saves laboratory space.
Powerful Functions: Offers professional test modes and data visualization capabilities.

Testing Principle
The system clamps a pre-treated sample between test chambers. Oxygen or nitrogen flows on one side, while high-purity nitrogen flows on the other. The diffusion of molecules through the film is measured to calculate transmission rates.

Reference Standards
Includes ASTM D3985, ASTM F1249, ISO 15106-2, and others, ensuring compliance with international testing standards.

Test Applications
Applicable to films and sheets, including plastic films, composite films, metal foils, and more.

Test for Improving the Functionality of Biodegradable Starch Plastics for Packaging-1

C406H Oxygen /Water Vapor Transmission Rate Test System C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985x ASTM F1249, ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others. Product Featuresnote1 OTR/WVTR tested in One Instrument • OTR \ WVTR mode, OTR mode and WVTR mode are available for selection. • OTR and WVTR tests can be automatically completed for each sample mounting. • Genuinely reflect the OTR \ WVTR performance of the same sample, avoiding effect on test data due to sample contamination arising from instrument switching Coulometric Oxygen Sensor • The instrument is equipped with a ppb level Coulometric Oxygen Sensor, as one of new Labthink technical achievements, which can obtain a lower limit of the test. • Designed according to ASTM D3985 with absolute value, and no calibration is permitted. • Longer service life, two times longer than that of a traditional Coulometric oxygen sensor. • Over limit alarm and automatic protection. Infrared Moisture Sensor • The instrument is equipped with Labthink patented infrared moisture sensor which can obtain a lower limit of the test. • Designed according to ASTM F1249. • Longer service life, non-consumable. • Over limit alarm and automatic protection. Accurate Data • Brand new rainbow bridge structural test cell and 360° air circulation constant temperature technology ensure better temperature stability. • The test cell is equipped with a high-precision humidity sensor to monitor and record humidity changes in real time.

Test for Improving the Functionality of Biodegradable Starch Plastics for Packaging-3

The pre-treated sample is clamped between the test chambers, oxygen or nitrogen with stable relative humidity flows on one side of the film, and the high purity nitrogen flows on the other side; oxygen or water molecules diffuse through the film into high-purity nitrogen on the other side, and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate can be calculated. Reference Standards ASTM D3985, ASTM F1307, GB/T 19789, GB/T 31354, DIN 53380-3, JIS K7126-2-B, YBB 000820032015...
