Máy kiểm tra tốc độ truyền oxy/hơi nước C403M dựa trên nguyên lý kiểm tra của cảm biến oxy điện hóa và cảm biến hơi nước hồng ngoại. Hệ thống được thiết kế và sản xuất theo các tiêu chuẩn như ASTM D3985, ASTM F1249 và ISO 15106-2. Nó cung cấp giải pháp kiểm tra tích hợp độ chính xác cao cho tốc độ truyền hơi nước và oxy của các vật liệu có rào cản cao và trung bình. Hệ thống được ứng dụng rộng rãi trong dược phẩm, thực phẩm, thiết bị y tế, hóa chất tiêu dùng hàng ngày, quang điện, điện tử và các lĩnh vực khác, giúp phát hiện chính xác hiệu suất truyền oxy và hơi nước của màng, bao bì, tấm và các vật liệu liên quan.

Product Features Note 1

Combining Tests of OTR and WVTR in One

The instrument can switch between OTR+WVTR combo test mode, OTR test mode and WVTR test mode freely, so as to satisfy varied testing needs.
One sample mounting can automatically start and accomplish the combo test of OTR and WVTR.
Both OTR and WVTR performances of the same sample can be accurately evaluated, avoiding sample contamination issues caused by instrument replacement.

Core Competence: Coulometric Oxygen Sensor

Equipped with a ppb-level coulometric oxygen sensor, Labthink's latest technical achievement, which can obtain a lower test limit.
Designed according to ASTM D3985 with absolute value test principle and no need for calibration.
Service life is three times that of traditional coulometric oxygen sensors.
Oxygen absorption rate is as high as 95~98% (within the range).

Core Competence: Infrared Water Vapor Sensor

Equipped with Labthink infrared water vapor sensor.
Designed according to ASTM F1249.
Non-consumable design ensures an ultra-long service life.
Features over-limit alarm and automatic protection functions.

Multi-dimensional Temperature and Humidity Control for Precise Data

360° airflow circulation constant temperature technology ensures superior temperature stability.
Automated control of carrier gas flow and temperature during testing ensures higher accuracy.
The NIST-standard humidity generation principle is applied for constant humidity.
Equipped with high-precision temperature and humidity sensors and control systems for real-time monitoring and recording of temperature and humidity changes.
Equipped with Labthink's independently developed gas purification system to remove trace oxygen from nitrogen, delivering ultra-pure nitrogen (optional).

Simultaneous testing of three samples under the same conditions can be performed with independent data.
Within one test cycle, the number of samples tested is increased from two to three.

Intelligent Control System Lowers the Barrier to Operation and Maintenance

10" medical-grade touchscreen paired with desktop operating system offers a simple interface and convenient operation.
Fully automated testing requires no manual intervention; data is automatically saved.
The system is equipped with various sensors, providing intelligent alerts and enhancing operational safety.
The system has embedded functions such as calendar, Ulti-language switching and multi-level access control, etc.
The system has an embedded network port for convenient external access and data transmission, enabling remote upgrades.

Multi-instrument Collaborative Management for Large-scale Testing

Next-generation platform-based computer software enables a single computer control of one or several instrument hosts (optional).
Centralized platform-based management of test data.
Real-time display of transmission rate curves, transmission coefficient curves, temperature curves, and humidity curves.
Professional test mode provides flexible and comprehensive control functions to satisfy scientific research needs.
Complies with GMP requirements for data traceability, meeting the needs of the pharmaceutical industry(optional).
DataShield System facilitates centralized data management and integration with information system (optional).

Low-carbon and Energy-saving, with Strict Control over Overall Costs.

Variable frequency control technology is applied to achieve low-power system operation.
Low-energy-consumption components from world-renowned brands ensure stable and reliable performance.
Computer is nota must; the instrument can independently complete the entire testing process.
Without a professional constant temperature laboratory, stable test data can be obtained, reducing costs for laboratory construction and daily operation and maintenance.

	Sheets	Oxygen and water vapor transmission rate tests for sheet materials such as PP sheets, PVC sheets, PVDC sheets, metal foil sheets, rubber sheets, and silicon wafers.
Extended Applications	Packaging Caps	Oxygen and water vapor permeability tests of the caps of various packaging.
	Solar Backsheet	Oxygen and water vapor permeability tests for solar back sheets and related materials.
	Pipes	Oxygen and water vapor permeability tests for PPR pipes and pipes made of various materials.
	Medical Blisters	Overall oxygen and water vapor permeability tests of medical blister packs.
	Vehicle Fuel Tank	Oxygen and water vapor permeability tests of plastic fuel tanks.
	Battery Housings	Oxygen and water vapor permeability tests for battery housings

Testing Principle

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 high-purity nitrogen flows on the other side. Oxygen or water molecules diffuse through the film into the 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 and other results are calculated.
