GfG G400 Motorized Smart Pump with Rechargeable Battery is used to remotely analyze toxic and flammable gases as well as oxygen deficiency before entering a confined space area. The G400-MP2 is to be used with the Microtector II G450 or G460. When the pump is switched on, the diffusion openings of the gas detection device are covered so that the measurement results are not influenced by the ambient air. Faults in the pump are also indicated on the gas detector's display thanks to smart communication with the gas detector. The pump's own power supply ensures that the gas detection device's battery life is not shortened during pump operation.
