酸雨观测仪器的日常使用维护及常见故障处理

Routine maintenance and troubleshooting of acid rain observation instruments

目前全国各酸雨观测站均采用雷磁PHS-3E型pH计和DDS-307A型电导率仪作为酸雨pH值和电导率K值的观测。在使用中,大多数观测员存在着不了解设备的工作原理以及在日常维护和常见故障排除中缺乏经验等问题。通过对酸雨观测仪器雷磁PHS-3E型pH计和DDS-307A型电导率仪在使用过程中进行的日常维护及对常见故障的总结,使观测员在酸雨观测中正确地使用该仪器,最大程度地提高酸雨观测准确率,减少复测次数,确保酸雨观测工作的正常运行。

At present,the acid rain stations in China have adopted the latest production of lightningsensitive PHS-3 EPH meter and DDS-307 Aconductivity meter that used to detect the PH value and K value of conductivity.During the operation,most observers do not understand the principles and lack of experience in routine maintenance and common troubleshooting.By using the acid rain observation equipment of PHS-3 EPH meter and DDS-307 Aconductivity meter with proper routine maintenance and summary of common faults,the observers can use the instrument correctly in acid rain observations,maximize the accuracy of acid rain observation,reduce the number of retests and ensure the normal operation of acid rain observation.
