ES-3000 Low-Cost Seismograph: |
| |
A
lightweight cost effective underground
imaging tool including an ultra-portable
recorder with all of the features.
If
you are a geoscientist doing teaching or
research, or just need an exploration
seismograph to find bedrock, the ES-3000 is
for you. The system includes
ESOS data
acquisition software and the ES-3000
seismodule connects directly to your PC via
the Ethernet port – no additional hardware
or drivers are required.
The ES-3000 system comes with all the data
analysis software you need to do
comprehensive refraction surveys to find
bedrock, the water table, where to rip, or
even outline gravel deposits. Geometrics
also offers special multi-license pricing on
the standalone version of SeisImager/2D so
that field crews and students can have their
own copies.
The ES-3000 comes with a 3-year warranty
backed by Geometrics, now in our 34th year
of prompt and knowledgeable customer support.
The ES-3000 is also available for rent.
Features:
-
Find bedrock,
depth-to-water, faults and fractures.
-
Ideal for
engineering, construction, road building,
and teaching.
-
Best quality data:
automatic settings, make no mistakes.
-
Lightweight (8 lbs/3.5
kg) and low-power.
-
Easy interface: no
complicated drivers, plugs directly into
your PC Ethernet port.
-
Includes analysis
software to give you quick answers in
the field and reports for your client.
-
Reduced noise and
cost: Data transmitted from ES-3000 to
host computer digitally, replacing long,
expensive analog cables with digital
cables.
-
Optional software
for blast and vibration measurements,
earthquake monitoring.

SeisImager/2D Lite data analysis software lets you model and plan
your survey before you get to the site. In the field, pick first
breaks and output cross sections by three different analysis methods.

Bundled Applications Software:
§
SIPQC refraction analysis software (delay time
method) from Rimrock Geophysics. Operates when
your laptop is connected to the ES-3000
§
SeisImager/2D Lite refraction modeling and
analysis software (time-term least squares,
delay time, and tomographic inversion methods)

1- Most laptop PCs
are NOT field devices. They are easily damaged
by harsh treatment or exposure to extreme
environments and have a short battery life.
Consider a ruggedized laptop PC designed for
outdoor use for surveys where reliability is
important. Please contact the factory with your
requirements |
