A tiny leak can lead to an entire batch of products being recalled and millions of dollars being lost. That's why more and more manufacturers are focusing on high-precisionAirtightness TesterThe choice.
In industries such as medical, automotive, and consumer electronics, the sealing requirements for products have reached extreme levels.Any tiny defects that are not visible to the naked eye can cause product failure, safety hazards, and even high recall costs in actual use.. Choose a high-precision machine that really fitsAir tightness testing equipment, has become a central challenge that manufacturers must face.
Step 1: Clarify what your "high precision" really is
Don't be fooled by the term "high precision".
Every vendor on the market claims that their equipment is 'highly accurate', but the concept itself is relative. The real key is this:How small of a leak does your product need to detect?
give an example::JC-C10005 Differential Pressure Leak DetectorA test accuracy of 0.075%F.S. or less indicates that the meter has a calculated deviation from the displayed value over the entire measuring range of the range value of the measured leakage value within the 2000Pa range.
The answer to this question directly determines what level of equipment you need:
- Small leakage (0.1 Pa pressure drop): Typically used in medical devices, precision electronic components, and other products that require very high levels of hermeticity. Requires top-notch sensor technology and environmental control, recommended to use Precision Industrial Technology'sDifferential Pressure Airtightness TesterThe
- General Precision Leakage (1 Pa pressure drop): Suitable for most consumer electronics, automotive parts, and more. This is the most balanced selection range in terms of price/performance ratio, and we recommend using Precision Engineering'sStraight pressure air tightness testerThe
- Standard Precision Leakage (10 Pa Pressure Drop): Suitable for general industrial product quality control, relatively low equipment requirements, recommended use of Jingcheng Industrial Technology'sEconomical Gas Tightness InstrumentsThe
Product characteristics determine the difficulty of testing
The characteristics of your product itself are the first threshold for selecting equipment:
| Product Characteristics | Difficulty of testing | Equipment Requirements | Instrument Selection |
| Small volume products (<50ml) | Easy to detect | Standard Precision Sensors | JC-FY80 Negative pressure air tightness tester |
| Large volume products (>500ml) | Detection difficulties | High Precision Sensors | JC-C10005 Differential Pressure Leak Tester |
| elastomer | Complexity of detection | Requires intelligent algorithmic compensation | JC-TC Series Positive Pressure Airtightness Tester |
| rigid material | Simple detection | Conventional equipment can meet the | JC-LC Series Economical Gas Tightness Instruments |
Step 2: Weighing Strategies for Core Technical Indicators
Sensor accuracy: the heart of the choice
The sensor is the heart of the entire device. But here's the key perception: it's not about higher accuracy, it's about matching your actual needs.
Choosing a sensor that is too accurate not only increases the cost, but may also generate more false alarms due to over-sensitivity. Choosing a sensor with insufficient accuracy may miss detecting real defects.
Selection criteria: The minimum detection capacity of the sensor should be 1/10th of the allowable leakage of your product to ensure detection capacity and to avoid over-sensitization.
Temperature Compensation: An Overlooked Critical Factor
Many people ignore temperature compensation when selecting equipment, which is a huge mistake. The pressure of a gas varies with temperature, and even a few degrees of temperature difference can cause the pressure to fluctuate beyond the true leak signal. Highly accurate testing equipment without effective temperature compensation is as unreliable as a precision balance without calibration.
Method of judgment: Ask the vendor how well the equipment maintains test accuracy over a ±5°C temperature change.
Data processing power: the value of intelligent algorithms
The competition for modern high-precision inspection equipment has shifted from hardware to software algorithms. Excellent algorithms can:
- Distinguish between product deformation and true leakage
- Automatic filtering of environmental disturbances
- Provides stable and reproducible results
- Enables fast voltage stabilization and accurate judgment
Step 3: The decisive role of workholding fixtures
Fixture quality has a direct impact on test results
Many people focus on the tester itself, but ignore the importance of the workholding fixture. In factThe sealing and stability of the fixture directly determines the upper limit of accuracy of the entire inspection system.
A leaky fixture, no matter how sophisticated the tester is, will not give accurate results.

The need for customized fixtures
Standardized fixtures are difficult to adapt to the specific requirements of different products. Specialized suppliers should be able to:
- Design special fixtures according to your product characteristics
- Ensure that the fixture itself is sealed
- Provide periodic calibration and maintenance of fixtures
Step 4: Decision-making framework for supplier selection
Criteria for judging technical strength
When choosing a supplier, don't just look at the product hype, focus on these substantive indicators:
- Project experience: Are there any successful cases of similar products? Can you provide relevant programs for reference?
- Services: Can it provide free technical consultation and program design? This reflects the technical strength and service attitude of the supplier.
- after-sales service: What is the completeness of equipment installation and commissioning, operational training, and routine maintenance?
Avoiding selection traps
There are some common selection traps in the market:
- Over-advertising accuracy: Some suppliers will exaggerate the accuracy of their equipment, which will not live up to the hype in actual use.
- Neglect of environmental adaptation: Focusing only on performance under ideal conditions ignores the complexity of real production environments.
- Lack of customization capabilities: Attempts to address specialized needs with general-purpose equipment often yield unsatisfactory results.
