Z400氯气检测仪 美国ESC公司 Z-400
|
Z-400是一款手持式仪器，可测量0-20PPM的氯气浓度，分辨率达0.1PPM。仪器带有LCD显示功能，声音报警。可在任何时候查看峰值，STEL(15分钟平均值）和TWA（8小时平均值）。

|
使用可选的数据记录功能，仪器可存储每一次使用的所有暴露点（最高5次测量）。对每个 系列的暴露点有一个相应的数据和时间标志。所有的存储器容量可以方便地上传到装有仪器配套的终端软件或微软Windows操作系统的计算机。

|
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氯气浓度成正比。

Z400 chlorine gas detector USA company ESC Z-400
Z-400 is a portable instrument, which can measure theconcentration of chlorine gas 0-20PPM, resolution up to 0.1PPM. Instrument with LCD display, voice alarm. To see the peak at any time, STEL (15 min average value)and TWA (8 hour average).
Data recording function, use the optional, the instrument can be stored for each time the use of all exposed point(maximum 5 measurements). There is a correspondingdata and time stamps for exposure point of each series.Memory, all can easily upload to the terminal software isinstrument or Microsoft 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. Sensor response values in the air and is proportional to the concentrationof chlorine.
