24/48 Channel Seismograph for Earthquake Masw seismic Refraction
Equipment
What is the WZG-24C/48C engineering seismograph?
The WZG-24C/48C engineering seismograph is a third-generation piece
of equipment that supports Windows 8 systems. It is
multi-functioning, high-precision, and stable. It can use seismic
sources such as the hammer, electric flicker, or explosion to
examine depths of up to 1,000 meters.
What are some applications of the WZG-24C/48C engineering
seismograph?
The WZG-24C/48C engineering seismograph can be used for seismic
surveys, sheared wave velocity tests, surface wave exploration,
pier foundation tests, ground micro-tremor determination, seismic
imaging, shake measurement, refraction or reflection surveys, and
more. It can inspect building bases, roadbeds, and civil
engineering, as well as explore roadbed caverns and lava,
delaminate quaternary overburden layers, sort foundation soil
types, survey hazardous geological bodies, and more.
What are some features of the WZG-24C/48C engineering seismograph?
The WZG-24C/48C engineering seismograph is an all-in-one unit with
high stability. It has an integrated tablet PC with a high
configuration and a reasonable structural design that is
shakeproof, dustproof, and waterproof. It also has a larger lithium
battery with a long endurance and fast sampling capabilities with
24-bit A/D and a minimum sample interval of 50μs for 24 channels.
