Plastic Film Gas Permeability Tester 

Model No.

N500/N530 Plastic Film Gas Permeability Tester 

Application: 

N500/N530 Plastic Film Gas Permeability Tester is used to determine the gas (such as O2, CO2 and N2) permeability/gas transmission rate (GTR) of various plastic film and sheeting, infusion bags and other package materials. It is designed using the principle of differential pressure method; the prepared sample is placed and clamped in the test cell with high/low pressure; then input the test gas into the vacuumized test cell to keep the constant pressure difference on the two sides of the test sample. Under the pressure difference, the gas will pass through the test sample from the high-pressure chamber to the low-pressure one; observe the pressure change in the low-pressure chamber is determined to calculate the permeability/transmission of the gas passing through the test sample. This instrument is widely used in food industry, pharmaceutical industry, cosmetics flexible packaging materials industry (plastic film, barrier materials, sheets, metal aluminum, PVC, PVC sheets), college, university and quality institution for gas (O2, CO2, N2, etc.) permeation test and quality control.

Features:

l        Three computer-automatically-control test cells for testing different samples with three independent sensors; each chamber can be set at different temperature; positive and negative pressure dual-mode testing method, leading international standard; (only for N530);

2        Three test cells can run at the same time or independently (only for N530);

3       Separately show the curve of transmission, pressure, pressure value and temperature;

4        High or low levels of barrier material test, excellent repeatability.

5       The international advanced electromagnetic process step temperature control technology, ease to arising  the temperature, variable temperature adjustable-rate, temperature controlled within the accuracy of ± 0.1 ℃;

6       An excellent environmental adaptability, no special requirements on the environment;

7        Real-timely display of the transmission at each point; the whole testing process can be observed through the transmittance curve;

8       The curve of each test cell's temperature, humidity, weight, and transmission display independently, continuously display four- groups-curve and monitor the interaction of parameters at the same time;

9        Friendly testing software interface, simple and easy to operate; can save and print the test report and other parameters and transmittance curve on it;

10        Excellent test reproducibility and overpressure protection;

11        Optional pairs of air humidity controlling devices, more precise of controlling wet;

12        Standard film for calibration and security alarms, such as alarm of upper and lower limit on the control panel, alarms of unclosed observation window, unclosed sample door, secondary capture and the zero position indicator;
