基于光离子化检测器(PID)传感器的便携式毒气检测装置

摘要

该装置采用光离子化检测器(PID)传感器进行检测,确保检测的快速性和准确性.装置设有气体选择模式,可准确地检测一氧化氮或硫化氢气体；同时可实现对一氧化氮或硫化氢气体的定量检测.及时、准确、可靠地显示实时的检测有毒气体的浓度,并根据设定的报警浓度提示使用者是否安全.%The device adopted a photoionization detector(PID ) sensor to detect, ensuring the detection speed and accuracy. The device is provided used a gas selection mode,can accurately detect nitric oxide or sulfide gas. It can realize the nitric oxide and hydrogen sulfide gas quantitative detection. It can timely,accurately reliably display real-time detection of toxic gas concentration , and according to the setting of the alarm to prompt the user whether the reliably concentration is safe.
