WZ-2 Gas Probe is primarily used in coal mines for collecting and sampling harmful gases from areas that gas inspectors cannot access, using a "receiving probe" of specific length. The collected samples are then analyzed by instruments to determine the concentration of relevant gases.
The 5-meter gas detection probe is simple to use, portable, and flexible. It can be connected to an instrument or a gas collection bag via a 5×8 rubber tube attached to the gas nozzle of the "receiving probe."
Technical Specifications
Gas probes are available in lengths of 1.5 meters, 2 meters, 2.5 meters, 3 meters, 3.5 meters, 4 meters, and 5 meters. Custom sizes can also be manufactured according to customer requirements. They are also referred to as gas detection probes, gas exploration probes, gas receiving probes, or gas inspection probes.
