What are the main models of JCGK Leak Tester? Airtightness tester chapter, with selection guide

As a leading brand in the airtightness testing industry, JCGK has launched a variety of airtightness testers to meet the testing needs of different industries and different application scenarios. From basic single-channel airtightness testing to high-end multi-channel automated testing equipment, JCGK's product line covers a wide range of testing needs.

Characteristics of Waterproof Breathable Membranes

Quick Q&A: Reliability Validation in the Waterproof and Breathable Membrane Industry—How Can Two Conflicting Properties Be Tested at Once?

This article explains how the waterproof and breathable membrane industry can simultaneously verify the two conflicting properties—waterproofing and breathability—through a comprehensive testing solution. Addressing the “water-blocking yet breathable” characteristics of ePTFE membranes, JCGK has proposed an integrated testing solution that resolves the issue of trade-offs in performance—which traditional single-parameter testing fails to detect—and supports quality control across all stages, from R&D validation to mass production automation.

How to Choose a Leak Test Solution for Liquid-Cooled Plates? A Decision-Making Model Based on Three Factors: Leak Rate Requirements, Daily Production Volume, and Operating Costs

This article addresses the scenario of 100% inspection on production lines in the airtightness testing industry, emphasizing that repeatability is more critical than accuracy. Based on 11 consecutive sets of actual measurement data from the JCGK Direct-Pressure Airtightness Tester by Jingcheng Engineering, the study verifies that its leakage values remain stable at 6–7 Pa, with fluctuations of only ±1 Pa. The paper analyzes the three key technological pillars supporting this performance—high-precision sensors, proprietary gas path control, and temperature drift compensation algorithms—and concludes with recommendations for selecting the appropriate model for different pressure scenarios.

Q&A: Why Is Leak Tightness Testing the First Line of Defense for Reliability Against the Risk of Micro-Leaks in Data Center Liquid Cooling Systems?

This article analyzes the requirements for high-precision airtightness testing in liquid-cooling systems for AI data centers and points out that the risk of micro-leaks is a core threat to system reliability. Using the Shenzhen Jingcheng Engineering JC-C10005 differential pressure leak tester as an example, the article illustrates how domestically manufactured equipment—through flexible customization, rapid response, and cost advantages—is gradually replacing imported equipment. It has become a critical component in the initial inspection of liquid-cooling production lines and, in combination with helium leak testing, helps ensure the autonomy and controllability of the industrial chain.

Can Domestic Airtightness Testers Replace Imported Ones? A Guide to Selecting Equipment: From “Replacing Individual Machines” to “Reducing Costs and Improving Efficiency on Production Lines”

This article explains that the core rationale behind replacing imported equipment with domestically produced airtightness testers has shifted from “low-cost substitution” to “value surpassing.” Taking the Jingcheng Engineering JC-C10005 series as an example, domestically produced equipment has achieved parity with imported counterparts in terms of differential pressure measurement accuracy and has established differentiated advantages in areas such as automation integration, service response speed, and total cost of ownership. Currently, substitution is well established in mainstream mass-production scenarios such as new energy, automotive, and home appliances; only in extreme scenarios such as aerospace does a gap remain.

Q&A: With the Cost of Helium Continuing to Rise, How Can Industrial Leak Detection Reduce Costs? Leak Tester Emerges as the Optimal Solution for Mass Production

This article provides a comparative analysis of the appropriate applications for helium mass spectrometer leak detectors and compressed air leak testers, pointing out that high-volume mass production lines do not need to blindly pursue the ultimate precision of helium testing; instead, adopting Jingcheng Engineering’s direct-pressure/ differential pressure/flow method, which not only meets industrial sealing requirements but also significantly reduces reliance on helium, improves production line efficiency, and achieves an optimal balance between cost and quality.

The Logic Behind Selecting a Leak Tester Brand for New Projects: How to Ensure Zero-Risk Production Line Implementation Using Proven Case Studies

This article explains how the manufacturing industry’s approach to purchasing airtightness testers is shifting from “buying standalone units” to “selecting comprehensive solutions.” Companies are no longer focusing solely on price but are instead viewing the equipment as a core quality control point on the production line. JCGK, a leading domestic brand, has become the designated supplier for projects in the new energy, automotive, and consumer electronics sectors thanks to its end-to-end solutions, rapid customization for non-standard requirements, localized services, and mass-production validation across multiple industries, successfully replacing imported products in high-end applications.

Q&A: How Can Leak Testers Improve Production Line Throughput? A Case Study of Optimizing Test Efficiency Using JCGK’s Engineering Model

This article analyzes the root causes of low efficiency in airtightness testing production lines at manufacturing enterprises: traditional testing equipment must complete a fixed test cycle regardless of whether a product has been deemed defective, resulting in a significant amount of “unnecessary waiting.” The article introduces JCGK’s solution—an intelligent early-detection feature that shortens the testing time per unit while retaining an engineering mode for comprehensive data collection during the R&D phase—and elaborates on efficiency-enhancing measures such as parameter optimization and multi-station parallel processing.

Localizing Leak Testers Isn’t About “Cheaper Alternatives,” but About “Choice”: A Carmaker’s Account of the Transition

Taking the experience of a certain automotive parts company that encountered “lock-in” while using imported airtightness testing equipment as a starting point, this article analyzes the risks of long-term lock-in inherent in equipment procurement within the industrial sector, explores the background and driving forces behind the rise of domestic alternatives in the airtightness testing industry, uses JCGK as an example to illustrate how domestic equipment has evolved from being a mere “substitute” to a “preferred choice,” and ultimately argues that a healthy industrial relationship should grant enterprises the right to diverse choices rather than single-source dependence.
