2026 Procurement Insider: How to Avoid the Low-Price Trap When Selecting Leak Testing Equipment

2026-06-04

This article exposes the hidden cost pitfalls associated with low-cost, domestically produced airtightness testers, pointing out that while initial savings of a few thousand yuan in procurement costs may seem attractive, they can lead to subsequent losses of hundreds of thousands of yuan due to misjudgments, customer complaints, returns, and failed factory audits. Using JCGK as an example, the article highlights the core advantages of established suppliers in terms of software algorithm stability, customized delivery, after-sales response, and international certifications, urging manufacturing companies to focus on the total cost of ownership rather than simply the initial price.

Real-Water Coating Combined with Precise Pressure: A Comprehensive Guide to the Efficient Testing Logic Behind the Water Resistance of Waterproof Breathable Membranes

2026-05-28

This article introduces the Water Pressure Resistance Tester for Waterproof and Breathable Membranes launched by JCGK. Utilizing a "real water coating + pneumatic loading" method to simulate real-world operating conditions, it provides an intuitive assessment of the water-blocking capabilities of membrane materials such as ePTFE. The device covers the membrane surface with water and applies pressure, displaying real-time leakage data. It supports high-definition observation of failure phenomena such as water droplets, wetting, and pinholes on the membrane surface, and allows for photo and video recording for archiving. It is suitable for R&D validation and mass quality inspection in industries such as new energy, automotive electronics, and consumer electronics.

QUICK Q&A: What is the difference between helium detection method and pressure drop method? How to choose the right hermetic gauge supplier

2026-04-29

This article is a quick Q&A comparing two mainstream solutions for leak testing: pressure drop and helium detection. Pressure drop method has low cost and high efficiency, and is suitable for routine sealing inspection; helium detection method has very high sensitivity, and is suitable for precision scenarios of micro-leakage control. Selection should be based on the allowable leakage rate, use scenarios, product structure and production line demand comprehensive judgment, and puts forward the five core criteria for selecting suppliers of hermetic tester.

Q&A: What are the requirements for the environment in which the airtightness tester is used? Please take this checklist

2026-04-17

This article analyzes the environmental requirements for the use of airtightness testers, pointing out that temperature, humidity, air pressure and vibration are key variables that affect testing accuracy. The article emphasizes that high-precision testing is more sensitive to the environment, and provides a list of common problems in the production line environment, suggesting that priority be given to five aspects of temperature stability, air source dryness, airflow interference, product heat balance and tooling sealing, rather than rushing to replace the equipment.

Q&A: The higher the precision, the easier it is to misjudge? Uncovering the real stability logic of production line airtightness testing

2026-04-10

This article exposes the "accuracy trap" in the procurement of leak tester, points out that marketing parameters such as 0.02% F.S. are misleading, and emphasizes that the detection stability depends on five system engineering factors: sensors, manifold seals, ambient temperatures, tooling and fixtures, and software algorithms. The authors propose that the selection should focus on the reading error (%rdg) and repeatability rather than full scale error, suggesting that the production line through the on-site testing to verify the performance, and that the domestic equipment in the system integration, cost-effective and service response has the strength to replace imports.
