 Gas analyzer FP 11.2K – measuring explosion-proof device with digital indication, light and voice signalization and built-in micropump. Gas analyzer FP 11.2K designed for measuring volume fraction of one of inflamable gases(methane, propane or oxygen) in air and light and sound signalization in case of volume fraction bounds violation. The device is used for control of gase cocentration in air in industial buildings, wells, cellars, holec etc. where dangerous and highly explosive gases categories IIА, IIВ, IIС, groups Т1...Т5 according GOST 12.1.011 can be found. Gas analyzer calibrating is available for methane and propane.
