It is a portable and tilt angle adjustable micro pressure meter, to be used for measuring the meter pressure and differential pressure. In addition, when working, it will be mated with a pitot gage to measure the wind speed, wind resistance and flow quantity in the ventilation system under a mine. Also it can be used for calibrating a wind meter. Read More

It is a detector to be used for checking the air tightness of a self-rescuer. It can be used to check the air leak of a self-rescuer rapidly and effectively. Read More

The product is based on the vacuum principle to inspect the air tightness of a self-rescuer. When it works, the in-built micro air pump will directly pump air to produce a negative pressure. Read More
