What are the common units of pressure for air tightness testers, and what is the difference between Pa, kPa and MPa?

Air tightness testerIt is a kind of instrument used to test the sealing and waterproof performance of productsIt 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

Airtightness Tester的压力单位有很多种，包括 Pa、kPa、MPa、mmHg、bar、mbar、psi 等。不同的行业或者说不同的地区，对于压力单位的选择是不一样的。因此，在使用Airtightness Tester时，经常需要进行压力换算。

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.

Airtightness Tester常见的压力单位有以下几种：

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.in choosingAirtightness Tester时，应根据实际测试需求选择合适的压力单位。

In addition, gas-tight instruments of准确性和可靠性是Airtightness Tester的重要指标之一TheHigh Precision Air Tightness Tester可提供可靠的数据，为企业的产品提供良好的质量保证。

因此，在选择气密性检测仪品牌时，应考虑其准确性和稳定性，以确保检测结果的准确性，提高生产效率。目前，JCGK 的High Precision Air Tightness Tester分辨率可达 0.1Pa，比肩甚至超过了部分进口品牌。

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.可以考虑选择用多通道的Air tightness testing equipment工作(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.
