Z1400XP二氧化氮检测仪 美国ESC公司 Z-1400XP
|
Z-1400XP二氧化氮检测仪是一款带内置采样泵的便携台式仪器，可测量空气中0-20ppm的二氧化氮，分辨率达0.1ppm。LCD显示屏每10秒钟更新显示一次浓度值（PPM）。Z-1400XP二氧化氮检测仪还会计算15分钟平均值和TWA（8小时平均值）。这些值可在测量过程中的任意时刻查看。结合可选的伸缩探头，可伸入难以到达的地方测量。

工作原理
Z-1400XP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。

Z1400XP NO2 detection instrument American company ESC Z-1400XP
Z-1400XP NO2 detection instrument is a sampling pumpwith built-in portable instrument, which can measure the air nitrogen dioxide 0-20ppm, resolution up to 0.1ppm.LCD display is updated every 10 seconds showed aconcentration value (PPM). Also Z-1400XP NO2detection instrument calculation of 15 min average valueand TWA (8 hour average). These values at any timeduring the measurement of the view. Telescopic probecombined with optional, can extend into the localmeasurement is hard to reach.
Data recording function using Z-1400XP NO2 detection instrument, can store every use of all exposed point. The maximum storage capacity of 14400 data points. This is the use of 1/5 every 8 hour average. Data can beuploaded to the terminal software is instrument orMicrosoft Windows operating system of the computer.
Working principle
Z-1400XP NO2 detector using a 4 electrodeelectrochemical sensor, including a working electrodeand an active auxiliary electrode. Signal emitted by theauxiliary 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.
