IPX9 can also be measured! Airtight real water leakage tester, locate the leakage point, multi-condition waterproof simulator

In the world of manufacturing, there is a pain called:

The airtightness meter results in an NG alarm, but you have no idea where the leak is.

The product is removed is dozens of screws, three layers of structure, five seals, dismantled you will suspect - leakage is not the product, is your life.

If you've experienced similar scenarios, congratulations, you've reached the common realm of engineers:

It's invisible to the naked eye, and the device just tells you it's leaking.
-- This is the darkest moment in airtightness testing.

And Seiko'sAirtight water leakage tester JC-WH500" emerged to crack this quality control challenge.

Ⅰ. Why are some products airtight NG but no leaks can be found?

This is not a technical flaw, butNatural limitations of the detection principleThe

Conventional airtightness testing utilizes pressure drop or flow rate methods, which essentially measure theOverall sealing performanceto determine whether a product passes or fails. It is logical:

• Filling the product cavity with gas
• Monitoring of pressure or flow changes
• Determine if there is a leak based on the value

The advantages of this approach areHigh accuracy, high speed, non-destructive testingIt can detect extremely small leaks. But its limitations are equally obvious:It gives holistic conclusions, not spatial localizationThe

It's like a doctor determining that you have a fever by your temperature, but not being able to directly see which organ is inflamed.

For products with simple structures, this is not a problem. But locating leaks becomes a nightmare when the product has the following characteristics:

Product Characteristics	localization difficulty	typical case
multicavity construction	extremely high	Automotive lamps and lanterns, new energy battery packs
concealed sealing surface	your (honorific)	Dual material injection molded shells, deep cavity products
Multi-Channel Seals	your (honorific)	Smart Wearables, Underwater Devices
Complex piping systems	extremely high	Solenoid valves, hydraulic lines

Engineers can only useexclusionary law: Take apart, inspect, reinforce, retest, and the cycle repeats itself. Efficiency plummets and time costs skyrocket.

II. Airtight + real water = leak site visible to the naked eye

Precision Engineering'sAirtight water leakage tester JC-WH500 A completely different idea of detection was used:Combines qualitative and localization testing in one unitThe

"Let the leaks go."come up on its own".

Video Presentation:Airtight water leakage tester

Its workflow has been carefully designed:

Step 1: Establishing a pressure differential

Positive, negative or mixed positive and negative pressure is applied to the product to form a pressure difference between the inside and outside of the product. The size and direction of this pressure difference can be set accurately according to the actual waterproofing level requirements.

Step 2: Underwater observation

The pressurized product is placed in water. At this point, if there is a leakage channel in the product, the pressure difference will drive gas to escape from the leakage point and form visible bubbles in the water.

Step 3: Precise positioning

Wherever there's a bubble, there's a leak.. This visual approach to positioning removes all uncertainty.

Behind this seemingly simple method is a deep understanding of detection principles:The essence of gas tightness testing is to discover the path of gas flow, and bubbles are the most visual evidence of gas flow.The

III. Why is it compatible with various IP waterproof ratings?

Because it supports three pressure modes:

• positive pressure
• suction
• mixed positive and negative pressure

What does that mean?

Whether you want to simulate:

• 1 meter water immersion for IPX7
• IPX8 deep water long-term pressure
• IPX9 high pressure hot water rinsing
• Even customized waterproofing standards

Precision Engineering JC-WH500 All can be handled with ease.

Example:

• Positive pressure suitable for simulating external water pressure: For sealed products that need to withstand external water pressure, such as diving equipment, underwater cameras. Corresponds to IPX7, IPX8 rating test.
• Negative pressure suitable for simulating internal vacuum suction: For products that need to prevent external liquids from being inhaled, such as medical devices and precision instruments.
• Mixed pressure applies positive and negative pressure simultaneously, or alternatively: Suitable for complex cavity configurations, especially products with multiple independent cavities, this mode exposes leakage paths that cannot be detected by traditional single pressure modes.

So it's essentially a "Multi-condition waterproof simulator".

Ⅳ. Which industries need it most?

It is suitable for almost all industries that require waterproofing, dustproofing and sealing, especially:

• smart wearable device (smartphone, tablet, etc)
• security camera
• Automotive lamps, radar housings
• New energy battery pack small cavity
• Medical device housings
• Food and pharmaceutical packaging
• Outdoor Tools
• Underwater equipment
• Solenoid valve, valve body, piping

which have complex structures, deep cavities, and strange leakage paths.The traditional air tightness meter can only judge whether the product is leaking or not, but cannot find out the leakage point, which often makes you collapse.The

(indicates contrast) JC-WH500 Directly allowing the leak to come to the surface in the form of an air bubble, theWhere it bubbles and leaks is visible to the naked eye.

V. Why do engineers like Jingcheng Engineering so muchairtight equipment?

The reason is simple:
It solves everyone's biggest headaches.

JC-WH500 The core selling points include:

• Positive pressure, negative pressure, positive and negative mixed pressure three modes can be selected
• Underwater pressurization to find leaks quickly
• Precision that is visible to the eye
• Suitable for IPX5, IPX6, IPX7, IPX8, IPX9
• Underwater high-pressure environment simulation
• Support non-standard customization

Behind these characteristics is theYears of industry experience accumulated by Precision Engineering::

• Feedback from more than 3600 renowned customers worldwide
• Serving new energy, auto parts, consumer electronics, security lighting, household appliances industries
• Development of specialized testing equipment solutions for different industry characteristics
• Self-developed algorithm optimized for "no leaks found".
• Highly matured mechanical structure, tooling design and pressure control.

One way to describe it is:
Truly understands the pain points of engineers, so makes a solution that works.

VI. The Ultimate Goal of Airtightness Testing Technology

Airtightness testing technology has evolved to the point where it is no longer satisfied with the "airtightness test".Problems found", but rather, to "TheQuickly locate problems and efficiently solve them".

in order toPrecision EngineeringAirtight water leakage tester JC-WH500 as representing the direction of this technological evolution:Combining precision measurements with visual observation, laboratory standards with production site requirementsThe

When engineers no longer need to face a pile of defective products at three o'clock in the morning to guess the location of leakage.When quality issues can be pinpointed and resolved within minutes, manufacturing efficiency gains are no longer an empty promise.The

That's what technological progress is all about:Allow professionals to focus on more valuable work instead of being consumed with repetitive trial and errorThe

Summarize

If your product encounters the following problems during airtightness testing:

• Failed the airtightness test but couldn't find the leak.
• Complex product structure and low efficiency of traditional inspection methods
• Need to meet multiple waterproofing ratings at the same time
• Need for non-standard customized seal testing solutions
