PURPOSE:To stabilize indication of the lowest digit, and to execute indication with accuracy higher by 1 digit than regular indication in case of calibration, by executing a special indication when a numeral of a lower digit corresponding to a value of standard gas is outputted as analytic information. CONSTITUTION:An output signal of a sensor S is inputted to a converter AD through an amplifier AMP, and upper 3 digits of a digital output of its 4 digits are indicated on a numerical indicator DP. Also, the lowest digit of the converter AD is led to a numerical detector DET, and its output indicates a decimal point of the indicator DP. |
