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.
Shore hardness tester measures the hardness of rubber sealing rings.
This article introduces the method of measuring the hardness of rubber sealing rings using a Shore durometer. The Shore durometer presses a needle into the rubber surface under spring force and converts the indentation depth into a hardness value, commonly using the A scale.
Sealing Tester Measures Leak Points in Flexible Packaging Bags.
This article introduces how a seal tester detects air leak points in flexible packaging bags. It primarily identifies leaks through changes in pressure or vacuum, and the operation involves preparing samples, setting parameters, and conducting standardized testing.
Insulation resistance tester measures rubber sealing gaskets.
This article introduces the method of using an insulation resistance tester to inspect rubber sealing gaskets.
Heat Sealing Tester Determines the Optimal Heat Sealing Temperature for Films
A heat seal tester is used to determine the optimal heat sealing temperature of films to ensure the sealing strength and integrity of packaging. During testing, by setting a temperature gradient and fixing parameters such as pressure and time, samples are heat-sealed at different temperatures, and then their strength is measured.
Daily Maintenance and Common Troubleshooting Guide for Titrators in the Laboratory
This guide introduces the daily maintenance and common troubleshooting methods for titrators. Daily maintenance includes cleaning and sealing checks of burettes and liquid pathways, proper storage and performance verification of electrodes, as well as inspections of the instrument's external environment and mechanical components.
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.
Principle and Application of Vacuum Decay Leak Testing Equipment
The vacuum decay leak tester is a non-destructive detection device that quantitatively detects leaks by monitoring minute pressure changes in the test chamber after vacuum evacuation.
The rain test chamber simulates heavy rain environments to test the waterproof sealing performance of products.
A rain test chamber is a device that simulates rainfall environments, used to evaluate the waterproof performance of product casings or sealed components. It tests electronic products, automotive parts, and other items in accordance with relevant standards by controlling water flow, water pressure, and spray duration.
