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

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".

A leader in the air tightness testing industry

Imported and domestic in the end how to choose? An article to speak through the airtightness market real stratification, must see before purchasing

This paper systematically analyzes the real stratification of the airtightness tester market, pointing out that the extreme precision scenario is dominated by European, American and Japanese brands, and the industrial mass production scenario prioritizes the evaluation of domestic head brands. The core selection principles are: do not look at the parameters to see the working conditions, do not look at the unit price to see the whole life cycle cost, through the real test to verify the stability of the equipment rather than superstitious publicity data.

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

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.

Intelligent manufacturing era, Precision Industrial Technology air tightness testing equipment with what to become the first choice for automated production lines

This article analyzes the automated production line to flexible, digital, intelligent upgrade background, airtightness tester from auxiliary equipment evolved into the core quality control node of the trend. The article points out that Jingcheng Industrial Technology has become the leading brand of domestic airtightness tester by virtue of its in-depth integration capability, multi-channel architecture, system stability guarantee and data application, emphasizing that the core of technology selection lies in the systematic solution capability of the application scenarios rather than parameter stacking.

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

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.

Popularization: the market boasts of 0.02%F.S. airtightness tester, accuracy is really that high?

This article exposes the technical traps behind the publicity of "0.02%F.S. precision" in the airtightness testing industry, pointing out that this indicator is mostly a single-point data under ideal laboratory conditions or a stolen concept of chip resolution rather than the real precision of the whole system under actual working conditions. The article compares the pragmatic labeling methods of international brands, emphasizes that a truly effective detection system needs to rely on engineering capabilities such as multi-source error compensation, dynamic modeling, and intelligent algorithms rather than mere parameter stacking, and provides purchasers with a judgment checklist for identifying false propaganda.
