As air tightness detectors have been widely used in the market to prevent and ensure people's work and life safety to a certain extent. It can simultaneously detect combustible gas, oxygen, carbon monoxide, hydrogen sulfide or other gases, and is suitable for safety inspections before entering various industrial hazardous environments and confined spaces.

During the leak test of the air tightness detector, if a leak is found in the test sample, it should not be directly repaired under pressure. Chalk can be used to mark leaks. After the leak detection of the entire system is completed, the air tightness leak tester will be repaired after the pressure is relieved.

In an open place, you can use the air tightness detector to continuously, real-time and accurately display the concentration of harmful gases in the poisoned place. Usually, it will be equipped with a vibration alarm or light alarm accessory to avoid not hearing the sound alarm in a noisy environment, and install a computer chip to record peak information and provide specific guidance for the health and safety of workers.

Air tightness test is carried out in winter. When the ambient temperature is lower than 0℃, the air tightness detector can add a certain amount of alcohol or white wine to the soapy water to reduce the freezing temperature to prevent the soapy water from solidifying and affect the leakage test effect to ensure the leak detection effect.

The number of repair welding of welded joints shall not exceed two times. If more than twice, the welded joint should be sawed off or the pipe should be re-welded with waterproof test equipment. If a slight leak is found, it should be repaired, and the method of punching and pressing must not be used to make it leak-proof. After completing the leak repair work, the pressure test should be performed again until the entire system does not leak.

In order to make the air tightness tester better play its value, you need to pay special attention to maintenance, which may affect the air tightness tester. In order to ensure the correctness of the test data, these factors have been comprehensively considered. Therefore, the maintenance of the airtightness detector is also the content of the protection work. Choose a qualified air tightness detector, use the correct operation method, and perform maintenance in time to ensure the smooth operation of the air tightness detector and prolong its service life, so as to play its best role.
