Z700一氧化氮检测仪 美国ESC公司 Z-700
|
Z-700是一款手持式仪器，可测量空气中0-100ppm的一氧化氮浓度，分辨率达0.5ppm。仪器带有LCD显示屏，电池电量低显示，和一个声音报警（可在传感范围内任意设置）。LCD显示屏每10秒显示一次当前一氧化氮浓度值（PPM）。可在任意时刻查看峰值、STEL(15分钟平均值）和TWA(8小时平均值）。

工作原理
仪器使用一个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一氧化氮浓度成正比。

Z700 ESC Z-700 USA nitric oxide detector
Z-700 is a portable instrument, which can be measured in the air of the nitric oxide concentration 0-100ppm,resolution up to 0.5ppm. Instrument with LCD display,low battery power display, alarm and a voice (can be setarbitrarily in the sensing range). LCD display screenevery 10 seconds to show a current nitric oxideconcentration value (PPM). At any time, the peak STEL(15 min average value) and TWA (8 hour average).
Working principle
The instrument uses 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 sensorresponse to nitric oxide concentration in the air and is proportional to the.
