Fully automatic two self rescue air tightness detector model: ZJQM-7

I. Overview
Product Features:
1. It can simultaneously detect two chemical oxygen self rescue devices, with a detection speed that is twice as fast as single detection devices on the market, and high efficiency;
2. Pneumatic assisted opening and closing of the upper cover is more labor-saving than manually opening and closing instruments on the market, reducing labor intensity;
3. The upper cover seal adopts a high torque electric pull rod, which has better sealing effect, faster speed, and is labor-saving and efficient compared to manual sealing;
4. Using STM32 processor technology as the core, it automatically controls the on/off of the air pump and solenoid valve, processes detection data automatically, and provides detection results. Compared to membrane pressure gauges and digital displays, this product has a higher degree of automation, accuracy, and efficiency;
5. Easy to operate, one click detection, automatic pressure release after detection, compared to other products that manually release pressure, greatly improving detection speed.
