One tool
for all your applications! The MI-3 series
inclinometer/deviation tools can be used in singleshot, multishot, and/or cable
(real time) modes. It is suitable for use in mining, oil&gas, and
geotechnical applications.

Software options:
MI3 tools come standard with software for Palm, Windows, and
DOS. Data collection and tool operation can be performed with a
Palm Pilot, ruggedized field computer, or laptop
computer.
Slimline design:
The deviation tool is available in a standard 25.4mm version (650m pressure
rating), or a 33.4mm version with integral pressure barrel (3500m pressure
rating). A pressure barrel is available for the 25.4mm tool.
Instant
results: Our borehole inclinometer uses data from a miniature three-axis
fluxgate magnetometer and a three-axis accelerometer to determine the
instrument orientation in space. The inclinometer operates in any
orientation. Data are recorded electronically and results are available in real
time (for cable operation) or shortly after the instrument is retrieved
(singleshot and multishot operation). There are no films to develop and read,
and there is no error-prone manual data entry to perform.
Magnetic
diagnostics: The MI-03 series inclinometers have other advantages over film
and gyro systems besides rapid data acquisition: the probes report on local
magnetic dip and magnitude - such information can aid the operator in
discarding data disturbed by local magnetization and can aid the geologist in
analyzing the geology. The data also indicate whether the probe was stationary
during the reading.
The inclinometer
produces 26 different output parameters, including dip, azimuth, field
strength, magnetic dip, magnetic toolface (high side), gravity toolface, and
temperature.
Specifications: Every MI-3 tool can be operated in a
single-shot, multi-shot, or wireline mode. In multi-shot mode, coupled with a
battery pack, as many as 3600 data stations can be recorded without any
electrical connection to the instrument (batteries are readily-available AA
cells). In wireline mode, a one conductor cable (as long as 10km) connects the
MI-3 to a computer that displays survey results in real-time. In any mode, you
can choose where and how often you want to stop and take readings.
