Product UsageOLB-1Sealing testerSuitable for sealing tests of packaging bags, bottles, tubes, cans, boxes, etc. in industries such as food, pharmaceuticals, medical devices, daily chemical products, automobiles, electronic components, stationery, etc. It can also be tested on specimens that have undergone drop and withstand voltage testsSealing performance test.

Product Features:

---

1. Adopting manual control for pressure maintenance makes operation more convenient and performance more stable.

2. All pneumatic components are made of manufacturer's products, with stable and reliable performance. Reduced pressure instability caused by pneumatic components.

3. Organic glass (acrylic) sealed bucket, with a wall thickness increased to 15mm, effectively enhances the compressive strength of the sealed bucket and extends its service life.

4. Electronic pressure holding device reduces mechanical wear and makes the holding time more durable.

5. PVC control panel, pressure pointer display, instant stability, convenient for users to quickly view pressure values.

6. Digital display of holding time.

Experimental principle:

---

By evacuating the vacuum chamber, immerse it in waterThe sample generates an internal and external pressure difference, and the gas leakage inside the sample is observed to determine the sealing performance of the sample; By evacuating the vacuum chamber to create an internal and external pressure difference in the sample, observing the expansion of the sample and the recovery of its shape after releasing the vacuum, the sealing performance of the sample can be determined.
