Wei Ru · Earthquake Research in Shanxi · 2003
After the experiment for 3 years in Seismic hydrochemistry experiment station of Liaocheng in Shandong,the 7 kinds of digital underground fluid observer instruments improved by GSB in the 9th Fiveyear plan were checked and accepted on November 1999.Through the overall summing-up for the operation and the observation data of the 7 kinds of digital instruments,the composite evaluation for the merits and shortcomings of the instruments was made,and the comparison of the digital record data with the anolog data was made also.The conclusion that the operation performance of the SD3A em anator of Radon,the GWK201 em anator of Helium and the LN3 digital water level meter is more stable,the observations are successive,accurate and reliable was obtained
