JQZ-1A/JQZ-2APositive pressure airtight detection device for mining self rescue device

Product features and uses:
The JQZ-1A and JQZ-2A self rescue device positive pressure and airtightness testing instruments (hereinafter referred to as the instruments) use positive pressure testing method and digital pressure gauge display to quickly and intuitively test the airtightness of the self rescue device. They have the characteristics of high measurement accuracy, intuitive display, compact structure, stable performance, and easy operation. This instrument is suitable for self rescue device manufacturers and users to conduct factory and daily air tightness checks on their products.

working principle:
Apply pressure to the sealing cover and sealing ring through the pressure handle and fasten the sealing hook to close and seal the working chamber. Due to the air pressure in the studio spreading outwards, a digital pressure gauge is transmitted to measure the pressure value.
