多参数检测仪
多参数检测仪是新一代智能型HYPERLINK"http://shop100787634.taobao.com/"检测仪，可连续检测存在易燃、易爆可燃性气体混合物环境中的气体浓度。具有声光报警、电压显示、欠压报警、零点自动跟踪、调校、使用方便等特点。多参数检测仪采用电化学氧气传感器，嵌入式微控制器智能控制，四位LED显示，一机两用。当仪器用于测量空气中的氧气时，电化学传感器以扩散方式直接与环境中的气体请打零贰玖捌捌柒贰陆柒柒叁反应，产生线性变化的电压信号。信号经线性放大器放大后输入单机内的A/D转换器转换为数字信号，经过微处理数据处理，由数码管显示出氧气浓度，当氧气浓度低于设定的报警点后，仪器发出声光报警信号。仪器具有电池欠压报警和自动关机功能。
