硫化氢是一种有毒气体,为保障人员安全,研制了数字显示携带式硫化氢分析仪。该仪器主要采用多孔Ag_2S电极和KOH-二甲亚砜电解液组成硫化氢传感器,用数字电路组成二次仪表,在仪器上可直接显示被测H_2S的浓度。仪器线路简单,读数直观,体积小重量轻,耗电量小,交直流两用,携带方便,适用于野外或车间现场快速分析。仪器响应时间小于1分钟,最低检出限为0.1ppm,测量浓度范围为0.1～9.9ppm。
Hydrogen sulfide is a toxic gas, to protect the safety of personnel, developed a digital display portable hydrogen sulfide analyzer. The instrument is mainly composed of porous Ag_2S electrode and KOH-dimethylsulfoxide electrolyte composed of hydrogen sulfide sensor, digital circuit composed of secondary instrument, the instrument can be displayed directly measured H_2S concentration. Instrument line is simple, intuitive readings, small size, light weight, low power consumption, AC and DC, easy to carry, for field or workshop site rapid analysis. Instrument response time of less than 1 minute, the minimum detection limit of 0.1ppm, the measured concentration range of 0.1 ~ 9.9ppm.
