Brief introduction: EC - 430 - hydrogen analyzer by microprocessor as the core of intelligent signal converter and electrochemical sensors, import. Applicable to the metallurgical, coal, electric power, chemical industry such as carbon monoxide, hydrogen sulfide, hydrogen, nitrogen oxides, sulfur dioxide content such as automatic analysis. Instrument using controlled potential electrochemical principle, the sensor from the working electrode W, electrode, reference electrode R C, when the gas being measured by sensors, oxidation reaction in W electrode, the oxygen reduction reaction in C electrode, W electrode with C electrode between the size of the output signal is proportional to the measured gas concentration. Technical indicators: Measuring range: 0 ~ 1000 ppmh2 Basic error: plus or minus 5% FS Zero drift and span drift: ≯ basic error The time lag: T90 60 s or less The gas flow rate: 300 ml/min Output signals: 4 ~ 20 ma (load resistance Ω 750 or less), and output signal corresponding to the measuring range is: 0 ~ 10 PPM, 0 ~ 100 PPM, 0 ~ 100 PPM The standard RS - 232 interface Measured value alarm, lower limit set:, the lower limit set values can be in with the output signal corresponding to the measuring range set arbitrary, the alarm contacts capacity of ac 220 v, 1 a Power consumption: 10 w or less Overall dimensions, the size of the hole Overall dimensions (disc) : 150 * 150 * 150 mm (width x height (deep)
