Pressure tester needs to pay more attention when using

Precision instruments, like porcelain dolls, can damage the instrument with brute force. The operation of precision instruments must be carefully used, installed, maintained, cleaned, etc. according to the instructions. The pressure tester is a high precision precision instrument.

Since the pressure calibrator is a high-precision precision instrument, in order to ensure its accurate use and prolong its service life, we must pay attention to its use to ensure that its detection accuracy is not affected by improper use.

First of all, the standard instrument and the instrument to be tested should be free of oily and corrosive substances and other impurities, otherwise it will affect the normal operation of the calibrator.

Second, when switching vacuum or pressure, the system must be at zero pressure.

In addition, the system must be in a zero-pressure state when the pressure gauge is removed.

Previous: Maintenance of power roller conveyor in daily work Next: Hydraulic universal testing machine is prone to problems and solutions

V-Profile Press fitting pipeline system is widely used in cold and hot water supply, heating supply, fire protection, medicinal gas, industrial petroleum pipeline system etc.

Compared with traditional pipeline system, it`s not only more economical, safer and healthier, but also easier and faster for installation with longer service life.
