GAS DETECTOR AND RE-CALIBRATION METHOD THEREOF

摘要

The present invention relates to a gas detector and, in particular, to a gas detector having a gas sensor corresponding to gas to be measured, wherein the gas detector of the present invention may correct a log value of gas measured next on the basis of a re-calibration reference value and a calibration value according to the concentration of the gas (the minimum output value of the gas sensor and an output value of the gas sensor which changes at every moment upon recovery after gas injection).
