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 Testing Equipment

• Leak Testing Equipment

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. The leak tester is a device that applies pressure (or vacuum) to finished products and parts that need inspection, detecting and measuring pressure changes with a high-sensitivity differential pressure sensor. By electrically detecting "leaks," it enables quantification and automation of the inspection process. For more details, please download the catalog.
