Description
GEA24 is a compact-sized 24 channel seismograph (can be serialised for a total of 48 chan.) with a 24 bit data acquisition board and USB interface for external PC (not included in the standard supply). Suitable for refraction, seismic tomography, downhole, crosshole, Vs30, MASW, shallow reflection applications, GEA-24 is a reliable, affordable solution for all professional uses.
Specification
Number of channels: 24 channels+trigger (chan. AUX) - 2 units can be serialised for a total of 48 channels Data Conversion : True 24 bit analogue/Digital Sigma-Delta converter (compatible with analogue geophones at any resonance frequency) Stacking: Unlimited number of stacking Input impedance: 2MOhm 22nF Dynamic range: 144dB (system); >117dB (instant, measured @1ksps) Distortion: 0.007% @16kHz Trigger: Normally closed contact, normally open (i.e. for use with explosives), analogue signal (starter geophone, piezoelectric starter), TTL trigger. Trigger sensitivity adjustable via software
