Z500一氧化碳检测仪 美国ESC公司 Z-500
|
Z-500是一款手持式仪器，可检测空气中0-300PPM的一氧化碳浓度，分辨率达1PPM。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秒显示当前的CO浓度（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碳浓度成正比。

Z500 carbon monoxide detector USA company ESC Z-500
Z-500 is a portable instrument, which can detect carbon monoxide concentration in the air 0-300PPM, resolution up to 1PPM. Instrument with LCD display, low battery power display, alarm and a voice (can be set arbitrarily in the sensing range). LCD display screen every 10 seconds to show the current CO concentration (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 sensor response of carbon monoxide concentration in the air and is proportional to the.
