Seismic recorder ZET 048-I
Digital seismic recorder ZET 048-I (industrial version) is used for measurements and recording of the signals obtained from the seismic receivers. The recorders can be used off-line or within the scope of automated systems for seismic and seismological surveys performance by means of refracted and reflected waves, seismic-refraction sounding, converted seismic wave method as well as in the course of geotechnical research.
The recorders have a variable amount of measuring channels: 4, 8 and 16.
