SMARTSEIS

Highest resolution low cost seismograph made
Fully automatic - no manual gain settings ensure good data in all conditions
In-field answers - built in software pick first arrivals, assigns layers and prints geologic cross section.
Logical, user friendly interface is simple to use, easy to remember.
Light weight and low power - operates from 12 V battery
Suitable for refraction, reflection, downhole or crosshole surveys.
Doubles as personal PC for processing your data
Daylight visible LCD screen, built-in printer.

The SmartSeis seismograph combines the best in low noise instrumentation with computer technology to produce a low cost, rugged instrument that is now considered by many as the industry standard.

If your works involves investigating beneath the ground's surface, teaching geophysical principles or even doing research, the SmartSeis helps you do your job better, faster and more reliably.

The user-friendly SmartSeis measures signals automatically - there is no possibility of poor data from incorrect settings. Built-in data quality control softwares gives preliminary answers right in the field on the built-in printer. Internal digital storage space is virtually unlimited. Data can be transferred by floppy or RS-232 to your PC for further study.

SPECIFICATIONS

Number of channels: 12 or 24
Sample interval: Selectable among 31, 62, 125, 250 and 500 microseconds.
Record Length: 2048 samples, or with the above sample rate, yields durations of 64, 128, 256, 512 or 1024ms
Filters and Noise Reduction Technology: Many field sites are noissy - moving vehicles, overhead power lines, vibrating machinery. The SmartSeis features noise reduction technologies and filtering to improve your data in the worst urban environments.
32 bit stacking: Reduces contributions from random noise
Memory Freeze: Allows selective stacking for weak channels
Low pass filtering: Reduces the effect of distant traffic
High pass filtering: Removes wind noise. Filters can be run in real time after data is collected making costly repeated shots unnecessary.
Low cut: 25, 35, 50, 70, 100, 140, 200, 280, 400 Hz
High cut: 250, 500, 1000
Power line notch: 50, 60, 150, 180
Anti-alias: Automatic
Custom filter frequencies available
Display: high resolution LCD, PC compatible, Visible in bright sunlight.
Noise Monitor: Waterfall style moving trace, also shows channel continuity and geophone performance
A/D Conversion: 20 bit result
Gain control: Automatic, set by continuously measuring two stage instantaneous floating point amplifier. True amplitude is preserved and can be used for ground motion studies.
Date Display: Wiggle trace, shaded or variable area, trace clipping, automatic gain control, fixed gain and post acquisition filtering included
Energy sources: Hammer, weight drop or explosives
Pretrigger delay: 0 to 9999 ms in 1 ms increments.
Pretrigger memory: allows viewing data before trigger.
Data Storage: sufficient for several days recording. Includes both floppy and hard drive storage.
In-field processing:
- automatic first arrival picking with manual over-ride
- On-screen travel time plots
- automatic layer assignments with manual over-ride
- automatic calculation of depths below shots and geophones. Program ray traces the data and indicates where data quality might be poor. Prints table of all data, depth calculations and a quality control plot showing questionable data. Report ready cross section with rock velocities printed last. Analysis and interpretation software from Rimrock gephysics.
Computer: '486 or optional Pentium. Optional computer interface provides RS-232, VGA, keyboard and printer connections.
Environmental: Operates from 0 to 50C. Water resistant with lid in place, operates in light rain.
