Z1400二氧化氮检测仪 美国ESC公司 Z-1400
|
Z-1400二氧化氮检测仪是一款手持式仪器，可检测空气中0-100ppm的二氧化氮浓度，精度达0.5ppm。LCD显示屏每10秒钟显示一次浓度值（PPM）。可在任意时刻查看STEL(15分钟平均值）和小时平均值。Z-1400二氧化氮检测仪还带有电池电量低显示和声音报警功能（可在0-100 ppm范围内任意设置）。

工作原理
Z-1400二氧化氮检测仪使用一个4电极型电化学传感器，包括一个工作电极和一个活性辅助电极。辅助电极发出的信号用于温度补偿，可增强整个传感器的选择性。传感器响应值和空气中的二氧化氮浓度成正比。

Z1400 NO2 detection instrument American company ESC Z-1400
Z-1400 NO2 detection instrument is a portable instrument, can detect the concentration of nitrogen dioxide in the air of 0-100ppm, the precision of 0.5ppm.LCD display screen every 10 seconds showed aconcentration value (PPM). See the STEL at any time(15 min average value) and the average. Z-1400 NO2detection instrument with low battery power display and sound alarm function (can be set arbitrarily in the 0-100ppm range).
Working principle
Z-1400 NO2 detector using a 4 electrode electrochemicalsensor, including a working electrode and an activeauxiliary electrode. Signal emitted by the auxiliary electrode used for temperature compensation, can enhance the selectivity of the sensor. The sensor response of NO2 concentration in the air and is proportional to the value of.
