Geophone String
Product Code : CD-3
Product Description

Description:

CD-3(SM24) geophone is functional as a high precision geophone, which has been self-developed by our company. Offered geophone is accessible with an advanced technology as well as a rational structure. The product can meet the increased consistency demand on specification of the geophone as well as high resolution seismic prospecting. Offered with better precision as well as small distortion ratio, it is suited for the formation such as beach, land, and lakes below 15 meters. The primary function of this product is to do the task of seismic prospecting in coal field, oil & gas field and mining field.
