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 it difficult to quantify the inspection results. A 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. Since it detects "leaks" electrically, quantification and automation of the inspection are possible.
