Z1300二氧化硫检测仪 美国ESC公司 Z-1300
|
Z-1300二氧化硫检测仪是一款手持式仪器，可测量空气中0-20PPM的二氧化硫气体，精度达到0.1PPM，是一款理想的二氧化硫测量仪。LCD显示屏每10秒显示当前的浓度值（PPM）。可在任意时刻查看STEL(15分钟平均值）和时间平均值。Z-1300二氧化硫检测仪还有电池电量低显示和声音报警功能，报警点可在0-20PPM内任意设置。

工作原理
Z-1300二氧化硫检测仪使用一个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硫浓度成正比。

Z1300 ESC Z-1300 USA sulfur dioxide tester
Sulfur dioxide Z-1300 detector is a portable instrument,which can be measured in the air of sulfur dioxide gas 0-20PPM, the accuracy of the 0.1PPM, is ideal for sulfur dioxide measuring instrument. LCD display screen every 10 seconds to show the current value of concentration(PPM). See the STEL at any time (15 min average value)and the time mean value. Sulfur dioxide Z-1300 detectorand a low battery display and sound alarm, the alarm can be set arbitrarily within 0-20PPM.
Working principle
Sulfur dioxide Z-1300 detector with 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 sulfur dioxide concentration in the air and is proportional to the.
