Gas Leak Tester

Gas leakage testers detect changes in pressure difference inside and outside a seal by pressurizing or evacuating it, using sensors to capture gas escape signals. They are used for verifying the sealing integrity of pipelines and containers, ensuring operational safety in chemical and medical equipment fields.
Selection
When selecting, consider matching the sensor type with the characteristics of the testing medium, ensuring the measurement range covers the pressure range of the test piece, and that the response speed aligns with the production line pace. The environmental temperature tolerance and explosion-proof rating must comply with on-site conditions, and the calibration cycle should integrate with the existing quality management processes.

Articles

Sealing tester measures the pressure resistance and leakage of composite film bags.
This article introduces how to use a seal tester to evaluate the pressure resistance and leakage performance of composite film bags. The test primarily involves applying controlled pressure inside the packaging and observing pressure changes or leakage to assess the quality of the seal.
Positive pressure method seal tester evaluates packaging pressure resistance
This article introduces how the positive pressure method sealing tester evaluates the pressure resistance of packaging. The instrument simulates actual pressure conditions by injecting compressed air into the packaging and then monitors pressure changes to determine if there is any leakage.
Negative pressure method leak detector for testing vacuum packaging seal integrity
The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.

Negative Pressure Method Sealing Tester for Detecting Leakage in Food Packaging
The negative pressure method seal tester creates a pressure difference inside and outside the packaging by evacuating air to detect leaks in food packaging. If there is a leak in the packaging, water will enter the packaging or produce continuous bubbles under the pressure difference, thereby determining the seal integrity. The test requires controlling parameters such as vacuum level and time, and should be conducted in accordance with relevant standards.
