Product Description
Detect the air tightness of the self-priming filter anti-particle respirators breathing valve air tightness tester
Product Description
Working principle
1. After closing the constant volume cavity with an airtight inspection cover, pump the system to a negative pressure of 1180Pa. No pressure change should be observed within 2 minutes after closing the control valve.
2. Install the sample to be measured on the constant volume cavity and ensure the tightness. At a pumping rate of not more than 500mL / min, the system can reach a negative pressure of 1250Pa and close the control valve.
3. Start timing when the negative pressure of the system drops to 1180Pa, and record whether the time required for the system to return to normal pressure is less than 20 S
Technical characteristics
1. High-definition 7-inch color touch screen, simple and convenient operation.
2. The micro-pressure sensor has high sensitivity and is used to collect test data pressure.
3. High-precision gas flow meter to accurately measure the leakage gas flow of the exhalation valve.
4. Convenient and fast pressure regulating device.
5. The product conforms to the third-level authority of GMP users.
6. Single and group statistical analysis of test results.
7. With ISP online control and upgrade function, the test function can be changed remotely as required;
8. Specialized computer communication software can perform real-time display of test, data analysis and processing, and data storage.
