摘　　要：以GSM-19T质子磁力仪为研究对象,依据不同性能指标,采用不同测试方式,对质子磁力仪特性进行系统测试。结果表明:该磁力仪操作简单、快捷,是具有数据采集数字化、精确测量自动化和高观测精度的便携式磁力仪,具有良好的稳定性和一致性,可以满足野外地震监测工作要求。GSM–19T proton precession magnetometer is widely used in seismic magnetic survey in recent years and becomes an important instrument in the area of earthquake monitoring. Taking GSM–19T proton magnetometers which are newly-purchased by China Earthquake Administration as the research objects, according to the different performance indexes, the study has conducted tests and systematical analyses for the main technical indicators of these proton magnetometers in different testing methods. The results showed that： GSM–19T proton precession magnetometer is a kind of easy-operating portable magnetometer applying skills such as the digital data acquisition, automatic measurement and higher observation precision. Besides, the good consistency stability of the instrument can also fully meet the requirements of seismic system.
