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.

Quick Question: Why do more and more manufacturing companies place more emphasis on source strength manufacturers when selecting an air tightness gauge?

2026-04-23

This article discusses the shift in the logic of purchasing airtightness testers in the context of manufacturing upgrading: enterprises have shifted from simply comparing parameters and prices to selecting source strength manufacturers with process understanding, system integration and continuous service capabilities. The article takes Jingcheng Gongke JCGK as an example to illustrate how domestic manufacturers can replace imported equipment through the ability to deliver complete solutions, and become a long-term technology partner for manufacturing upgrades.

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.

Airtightness tester selection guide: direct pressure, differential pressure, volumetric method of the essential differences and practical choice

2026-04-02

This article introduces the working principle, applicable scenarios and selection decision logic of the three commonly used methods (direct pressure method, differential pressure method and volumetric method) of the airtightness tester. The direct pressure method is suitable for products with holes, low cost but limited stability; the differential pressure method eliminates interference through comparative measurements, with an accuracy of 0.1 Pa, which is suitable for high-precision micro-leakage detection; the volumetric method is specially designed for fully enclosed products with no openings to realize non-destructive sealing inspection. Selection should be based on a combination of product structure, accuracy requirements and production line schedule to avoid falling into common traps such as "low price is enough" or "ignoring the jig".

Q&A: Bought a high-precision airtightness meter but it's just for show? Be alert to the three major misunderstandings of automated production line integration

2026-03-26

This paper points out the contradiction between the high-speed production of automated production lines and the traditional sampling mode, and emphasizes that the core value of on-line airtightness testing is to change the quality control from "probability game" to "certainty guarantee". It analyzes the three major misconceptions of the failure of enterprise deployment of equipment (stand-alone thinking, neglect of tooling design, data silos), and puts forward the key dimensions of technology selection, and finally illustrates the practical value of systematic integration with the case of Precision Industrial Technology.

Quick Q&A: Why are your hermetic test results erratic? The Truth About Airtightness Detection Accuracy

2026-03-20

This article reveals the core reason for the instability of the accuracy of the airtightness tester: detection accuracy is not determined by a single sensor parameter, but the temperature, valve sealing, sensor performance, tooling structure, software algorithms, the five factors linked to the system capabilities. The article criticizes the phenomenon of excessive speculation in the industry sensor parameters, emphasizes the stability of the machine and the actual working conditions is the key to selection, and introduces the advantages of the national brand Jingcheng Gongke (JCGK) of the system-level solutions.
