Leak Test Laboratory

Leak Test Laboratory

Data collection is possible with samples! Leak inspection, leak test laboratory.

At NAKK, we have established a "Leak Test Lab" to help you gain a deeper understanding of leak testing. By sending us samples in advance, we will select the testing method, collect data, and report the optimal setting time and detectable leak amounts. We will assist you in introducing the most suitable method to your test line. 【Common Issues】 - Already using a leak tester, but it is unstable. - Need to perform leak tests but do not know how. 【What You Can Experience】 - Selection of leak testing methods for brought-in work - Data collection with samples - Technical guidance - Training - Suggestions for optimal test line introduction methods 【Cost】 Basically free of charge. *We will only charge necessary expenses for items that require fabrication, such as sealing jigs.

Leak Tester Technology Introductory Book Free Download Campaign

Leak Tester Technology Introductory Book Free Download Campaign

Just by reading, you can understand leak testing technology! An introductory book on leak testers.

Many of the items, facilities, parts, and machines necessary for production that we use in our daily lives must not allow their contents to leak, either internally or externally. For example, if there is a leak in gas or water piping components, it is a waste of resources and can sometimes be dangerous. Let's make good use of leak testers to prevent "leaks"! == New Product == Differential Pressure Leak Tester NLT-330 It detects leaks with high precision by comparing measurements with a leak-free master. Its compact design makes it easy to operate. You can preset up to ten different conditions, allowing for easy recall based on the workpiece. Highly recommended for beginners in leak testing!

Leak test device for water meter units

Leak test device for water meter units

We will automate and standardize airtightness testing to contribute to the improvement of quality and production efficiency.

In today's production factories, depending on the product, a "leak test" for all items is required to maintain high manufacturing quality. However, the conventional "submersion visual inspection" is labor-intensive and makes quantifying the inspection difficult. A leak tester is a device that applies pressure (or vacuum) to finished products or parts that need inspection and detects and measures pressure changes using a highly sensitive differential pressure sensor. By electrically detecting "leaks," it enables quantification and automation of the inspection process. For more details, please download the catalog.

Leak Tester (Low Price Type) NT-600

Leak Tester (Low Price Type) NT-600

Low-cost leak tester ideal for service departments and more.

A leak tester is a device that electrically detects pressure changes with high-precision differential pressure sensors during airtightness (leak) testing of products and parts. Unlike submerged testing, it does not wet the workpiece, eliminates individual differences, and allows for numerical testing. It is easy to integrate into automated systems. NAC's leak testers enable the automation and standardization of airtightness testing. They are widely used in applications requiring high-precision airtightness testing, such as gas-related, water supply, electrical equipment, automotive parts, medical devices, food containers, and pneumatic and hydraulic equipment. For more details, please contact us or download the catalog.

Please feel free to consult us about anything related to leak tests.

Please feel free to consult us about anything related to leak tests.

Nack's leak tester, with excellent features such as "easy," "high-precision results," "short time," "low cost," and "automatable," solves your problems!

The leak tester applies pressure or vacuum to finished products and components, and electrically detects pressure changes in the event of a leak using a highly sensitive differential pressure sensor. Since leaks are detected electrically, it is easy to quantify and automate leak testing, which was not possible with traditional visual inspection methods. The elimination of the drying process and the removal of individual differences in detection capability are also significant advantages. We provide testing machines that are particularly suitable for airtightness testing of automotive parts, gas/water supply components, mobile phones, digital cameras, and medical devices. We will verify the testing methods that match your testing conditions at the leak test lab. *For examples of leak tester implementations, please visit our website. For more details, please download the catalog or feel free to contact us.
