Product Introduction
OTR-D3 Oxygen Transmission Rate Tester (OTR Tester) is manufactured based on the coulometric sensor method and is applicable to test the oxygen permeability of medium and high barrier materials such as plastic films, composite films, sheets, papers, and other packaging materials used in food, pharmaceutical, medical device, consumer products, and electronic industries, etc.
Features
● High precision infrared sensor is used to ensure the testing accuracy
● Automatic humidity and temperature control to guarantee the stability of the testing environment
● All test operations are performed on a computer with testing software. User-friendly interface for easy and simplified operation.
● Test data and curves are displayed in the real time
● 3 independent test chambers for 3 test samples
● Automatic test operation by one-button clicking
● Patented pipeline flushing design ensures cleanliness of carrier gas and high testing efficiency
● Unique sample leak-proof seal installation technology enhances the seal performance of test chambers
● Meeting the requirements of USP 1207 United States Pharmacopoeia Standard for data traceability, rights management and other functions, the computerized system fully meets the needs of the pharmaceutical industry (optional)
Testing Principle
The pre-conditioned specimen is clamped in the test cell, oxygen or air flows on one side of the specimen while a stream of high-purity nitrogen flows on the other side. Oxygen molecules permeate through the specimen into the nitrogen side and are carried to the coulometric sensor. The sensor analyzes the oxygen concentration and calculates the oxygen transmission rate and other factors..
Test standard
ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, ISO 15105-2, JIS K7126-B
Configuration
Standard Configuration: main instrument, sampler, nitrogen/oxygen cylinder pressure reducing valve, Dow Corning vacuum grease
Optional: package test accessories, package temperature control device, constant temperature control device
Note: Air sources (nitrogen and oxygen) shall be prepared by the user
