Mini-Seis™ Options

Transducer Sensitivity

The standard transducer sensitivity is termed a 2G.  Recording levels can range from 0.005 ips (0.127 mmps) to 10.24 ips (260 mmps).  We also offer X1, X4 and X8 geophone gains, which modify the standard X2 gain proportionally.  These are standard options.  We can also do custom gains based on specific needs.

Microphone Sensitivity

The standard microphone is limited to 148 dB.  We also offer a standard option 160 dB microphone.  If necessary, we can supply microphones capable of recording up to 5 or even 10 psi (185 to 190 dB).

Downhole Sensor

We offer a downhole sensor package for special needs.  The package is sealed and is designed to fit inside a standard PVC pipe for easy installation.  The electronics are kept in a separate container.
