Air tightness tester is an instrument used to test the sealing and waterproof performance of the productIt is also known as the "Leakage", because it analyzes the inside of the product by inflating the inner cavity, cutting off the air source and stabilizing the air pressure while calculating the differential pressure of the product leakage to determine whether the product is leaking or not, and it is also called the "Leakage".airtightness leak detector,Sealing Tester,Waterproof TesterThe
There are many kinds of pressure units for air tightness tester, including Pa, kPa, MPa, mmHg, bar, mbar, psi and so on. Different industries or different regions have different choices of pressure units. Therefore, pressure conversions are often required when using an airtightness tester.
Pascal (Pa), kilopascal (kPa) and megapascal (Mpa) are all units of pressure, the difference being mainly in the range of pressure values they represent.The pascal (Pa) is a unit for very small pressures, the kilopascal (kPa) is a unit for smaller pressures, and the megapascal (Mpa) is used for larger pressures. Specifically:
1 Pascal (Pa) equals 0.001 kilopascal (kPa).
1 kilopascal (kPa) equals 1000 pascals (Pa).
1 megapascal (MPa) equals 1000 kilopascals (kPa), or 1,000,000 pascals (Pa).
The conversion relationship is: 1 MPa = 1000 kPa = 1000000 Pa.
The following pressure units are common for air tightness testers:
1. Pascal (Pa)International Standard Units: 1 Pa equals 1 N/m².
2. Kilopascal (kPa): 1 kPa equals 1000 Pa
3. Megapascals (MPa): 1 MPa equals 1000 kPa, or 1,000,000 Pa.
4. Millimeters of mercury (mmHg): 1 mmHg equals approximately 133.3 Pa, measured as the height of a column of mercury, defined as 760 mmHg equal to standard atmospheric pressure.
5. Bar (bar): 1 bar equals 100 kPa.
6. millibar (mbar, also known as hectopascal, hPa)): 1 mbar equals 100 Pa.
7. Pound force per square inch (psi): 1 psi equals approximately 6894.76 Pa, which equates to a force of 1 pound per square inch.
8. Standard atmospheric pressure (atm): 1 atm equals 101.325 kPa and is usually used for gas pressure measurement.
The unit of pressure refers to the force acting vertically on the surface of an object. The above are common units of pressure and conversion relationships, but other units or different conversion relationships may be used in different fields or in different countries/regions.When selecting an airtightness tester, the appropriate pressure unit should be chosen according to the actual test requirements.
In addition, gas-tight instruments ofAccuracy and reliability are one of the most important indicators of an airtightness tester.TheThe high precision air tightness tester can provide reliable data and provide good quality assurance for the products of the enterprise.
Therefore, when choosing the brand of airtightness tester, its accuracy and stability should be considered to ensure the accuracy of the test results and improve the production efficiency. At present, JCGK's high-precision airtightness tester resolution can reach 0.1Pa, comparable to or even exceeding some imported brands.
Secondly, detection speed is also very important for certain scenarios. If you needRapid testing of a large number of productsInstead, it is necessary to choose an instrument that is capable of completing the test in a short period of time.Consider the option of working with multi-channel airtightness testing equipment(math.) genusMulti-station operation for simultaneous testing of several products at a time(math.) genusIt can double the productivity and create great economic benefits for companies and factories.
Good and bad product leakage value is so big difference? Medical dual-channel airtightness tester, the waterproof performance of the water tank test comparison
