Introduction
The Model 3005 is an ergonomic, lightweight instrument with an
internal detector used for radiation survey. The instrument features a
large backlit LCD (liquid crystal display), a piercing audio warning, and
easy, intuitive use. The unit body is made of lightweight but durable
plastic. It is intended for outdoor use and can resist splashing water.
Versions: While the standard Model 3005 has an internal Energy-
Compensated Geiger-Muller (ECGM) detector, other detectors are
possible:
3005: ECGM with range 0.1-5000 mR/hr or 0.001-50 mSv/h
3005/3: ECGM with range 0.1-25000 mR/hr or 0.001-250 mSv/h
3005/4: ECGM with range 1-50000 mR/hr or 0.001-500 mSv/h
Three modes of operation are available for the Model 3005 –RATE,
MAX, and COUNT. RATE mode operation will display the current
exposure, or dose rate. MAX mode is used to capture the highest
exposure or dose rate detected –useful for finding a peak rate when the
display is not visible. Two sets of units (primary and secondary) for
RATE and MAX modes can be chosen from among cps, cpm, Bq,
dpm, R/h, or Sv/h. The user can switch between these two units by
simply tapping the Units button. If not needed, the 2nd set of units can
be disabled. Also, the additional MAX and COUNT modes may also be
disabled, reducing the possible number of displays the user may
confront.
COUNT mode allows the user to perform a count for a predetermined
time. Depending on the count units chosen, the result can be a scaler
count (in counts or disintegrations), a time-averaged rate (cpm, dpm,
Bq, cps), a time-averaged exposure or dose (R/h, Sv/h), or an
integrated exposure or dose (R or Sv).
The display will be automatically backlit if light levels are low. The
display backlight can also be configured for “Continuous On”
operation. Radiation level alarm points can also be configured.

The Model 3005 comes with the ability to log measurements to memory
for later download. The optional Ludlum Lumic Datalog software is
needed to download this memory, however. The unit can log up to
1000 measurements, and it adds a date/time stamp to each
measurement.

Front-panel setup can be disabled via the internal switch on the Model
3005 in order to protect settings from inadvertent changes.
The unit is operated with four alkaline AA batteries for operation from
-20 to 50 °C (-5 to 122 °F). Battery life is approximately 750 hours
under normal usage. A low-battery indicator on the LCD warns when
less than 16 hours of battery life remain.
