    High Pressure Leak Detector

    Overview Knowledge Standards Terms
    The high-voltage leak detector applies high-voltage electricity to detect surface or internal defects in insulating materials, generating visible discharge sparks or audible and visual alarms. It is used to identify leakage points such as pinholes and cracks in materials like plastic films, rubber products, and insulating sleeves, ensuring the sealing performance of products.
    Selection
    Select the test voltage range based on the thickness of the object being measured, determine the AC/DC output mode according to the material type, choose a portable or benchtop structure based on the production environment, match the sensitivity adjustment function according to the detection accuracy requirements, and confirm the grounding protection device in accordance with safety standards.

    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.
    Arc Resistance Tester measures the arc resistance performance of resin surfaces.
    The arc resistance tester is used to evaluate the ability of insulating materials such as resins to withstand high-voltage arcs on their surfaces.
    High Pressure Accelerated Aging Tester Evaluation of Paint Resistance to High Temperature, High Humidity, and High Pressure Environments
    This article introduces how a high-pressure accelerated aging test machine evaluates the durability of colored paint under high temperature, high humidity, and high-pressure conditions. The test machine simulates these conditions to accelerate the aging of the coating and observe whether issues such as discoloration or blistering occur.
