Description:
I: Application:
SM - 20 magnetic susceptibility can be used in a wide range of geography and geology, unique sensitivity for 10-6SI, but it is light enough,which can carried in pocket.
SM - 20 special field geological exploration and with rapid laboratory analysis, the analysis of rock or core analysis and classification. Can detect and paramagnetic magnetic, ferromagnetism nuances of rocks and accurately gives the rnagnetizable rate. Using the traditional sensor and signal processing methods of new instruments in a leading position. There are two key operations, one foe measuring, the other for storage. Other operations can use computer to complete, it can give point marker, write, storage measurement data point to down further treatment. Lithium battery and automatic shutdown function to cooperate, can not change the battery in the situations long-term work.
II: SM - 20 magnetic susceptibility instrument technical characteristics:
1, sensitivity: 1 x 10-6 SI've
2, measurement range: 0.000 to 10-3 SI 999 x've adjusted automatically, measurement range
