Differential pressure leak tester

This is a differential pressure leak tester handled by Nack. Due to consistent in-house development and production, we can offer leak testers at a low price along with significantly reduced lead times during implementation.

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.

Differential Pressure Leak Tester NLT-720

You can perform airtightness testing without wetting the work and without individual differences. It can accommodate products with different set conditions.

The differential pressure leak tester NLT-720 is a tester that electrically captures pressure changes with a high-precision differential pressure sensor for airtightness (leak) testing of products and parts. Unlike submerged testing, it is a testing device that does not wet the workpiece, allowing for numerical testing without individual variation. It is also easy to integrate into automatic machines. For more details, please contact us or download the catalog.

Differential Pressure Leak Tester NLT-330

A leak tester that allows measurements without wetting the work, such as in water immersion tests.

This is a leak tester manufactured by NAKK that enables the automation and standardization of airtightness testing. It allows for comparative measurement against a master with no leaks, providing numerical inspection results, and can perform measurements without wetting the workpiece, such as in submersion tests. It is widely used in various fields requiring high-precision airtightness testing, including gas-related, water supply, electrical equipment, automotive parts, medical devices, food containers, and pneumatic and hydraulic equipment. ■ Features - High precision leak detection due to comparative measurement with a leak-free master. - Compact design for easy operation. - Up to 10 preset conditions for various settings, allowing for retrieval based on the workpiece. ■ Functions Auto Zero: Zero correction of the value just before measurement. Correction: Adjusts measurement noise based on the workpiece. Judgment Signal Selection: Choose between pulse/hold for OK and NG signals after judgment. Various Check Functions: Self-checks for valves, sensors, test pressure, etc. Hold: Holds the value at the end of measurement. Options: Analog output, communication functions such as RS232C, SD card data collection unit. * We also respond to the design and manufacturing of attached devices. Please feel free to consult us.

Differential Pressure Leak Tester "NLT-730T2" - Ideal for Sealed Workpieces

Automation and standardization of airtightness testing is possible! We also respond to the design and manufacturing of auxiliary equipment.

The NLT-730T2 is a leak tester suitable for products without an air supply port, such as sealed products. It detects leaks with high precision by comparing measurements with a leak-free master. The operation is via a color touch panel with a width of 134 mm and a height of 92 mm, featuring a wide screen. Measurements are taken twice: the first time with reduced sensitivity to detect large leaks, followed by a second measurement for detecting small leaks. 【Features】 - Automation and standardization of airtight testing are possible. - High precision leak detection through comparison with a leak-free master. - Particularly suitable for products without an air supply port, such as sealed products. - Especially designed for products with minimal spatial volume. - Operation is via a color touch panel with a width of 134 mm and a height of 92 mm, featuring a wide screen. *For more details, please refer to the PDF document or feel free to contact us.

Six-axis robot leak test device

Fully automated leak test device.

It was very difficult to set the workpiece using a robot in a leak test where a clamping mechanism is essential to seal the workpiece. However, by using a six-axis robot, we were able to gain a certain degree of freedom in movement, which allowed us to resolve the issue. Additionally, for the loading and unloading, we use air cylinders to keep the slide end in its original position, which results in a design that minimizes displacement in the Y (X) axis. We are moving away from conventional semi-automatic machines (manual workpiece setting) and achieving online automation.
