Z900XP硫化氢检测仪 美国ESC公司 Z-900XP
|
Z-900XP是一款便携台式仪器，可测量空气中0-50PPM的硫化氢气体（还能达到0-200PPM），分辨率为0.1PPM。LCD显示屏每10秒显示一次浓度值（ppm）。仪器还会计算15分钟平均值和8小时平均值。这些数据可以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
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硫化氢浓度成正比。

Z900XP hydrogen sulfide detector America company ESC Z-900XP
Z-900XP is a portable instrument, which can hydrogen sulfide gas 0-50PPM measurements in air (0-200PPMcan reach), the resolution is 0.1PPM. LCD display screen every 10 seconds to show a concentration value(ppm). The instrument also calculate average value in 15 minutes and 8 hour average. These data can be at any time during the measuring process view. Telescopicprobe combined with optional, can extend into the localmeasurement is hard to reach.
The use of data recording function, the instrument can be stored for each time the 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
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 hydrogen sulfide concentration in the air andis proportional to the.
