Oxygen Transmission Rate (OTR) Test System is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985 and ISO 15105-2.Figure1. Test Principle of Differential-pressure Method . Differential pressure method has no selectivity to test gas. It is low in test cost and high in test efficiency. The most salient feature of this method is that the gas is pure in the test environment.
A second drawback of the absolute pressure decay method is the effect of the Adiabatic Process; when the item is brought up to test pressure there will be an increase in temperature. Subsequent heat dissipation may lead to a pressure decrease during the test phase, which the instrument will incorrectly perceive as a leak. The Differential MethodPERME® VAC-V2 Gas Permeability Tester VAC-V2 is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, and aluminum foils.VAC-V3 Gas Permeability Tester is applicable in the measurement of gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, high barrier material, sheets, foils, etc.

Permeability Measurement
OTR values are used to compare the relative oxygen barrier capabilities of packaging films. An industry rule-of-thumb is that a material is considered a "high oxygen barrier" if its OTR is less than 1 cc/100 in 2 /24 hr (15.5 cc/m 2 /24 hr). Table 10 shows OTR values for common polymer packaging films. Note that the table is divided into two .CO2 transmission rate test by weighing method: Water vapor transmission rate test by inverted cup method: Non-destructive test for packaging seal performance: Multi-station packaging pressure test: Tensile test of packaging materials with ultra-long elongation: Heat-seal strength test for cap films of medical bottles, yogurt cups and jelly cups The test is carried out by the N530 2.0 Differential Pressure Gas Transmission Rate Tester independently developed by Guangzhou Standard, which is based on the testing principle of differential .Test Procedure for Double Check Valve Assembly (DCVA) Using a Differential Pressure Gauge Test No. 1 Purpose: To test check valve No.2 for tightness in the normal direction of flow.
