Compact Geo-Explorer - Model 4404-16-4
Introduction

The Ludlum Model 4404-16-4 Geo-Exploration System provides radiation surface measurements to help discern the underlying geology of the targeted area. This instrument serves as an excellent oil exploration and ore prospecting tool. Compact size, moderate weight, and generous battery life enable the operator to cover territory in an efficient and convenient manner.
 
This system is comprised of a scintillation detector, multichannel electronics, a waterproof carrying case, wireless transceiver, rechargeable battery, and Geo-Explorer PC software program. The weatherproof enclosure is sized to easily fit into a moderately-sized backpack (not provided). The instrument can run on battery power for up to 15 hours. The output is transmitted once each second wirelessly so there are no interconnecting cables required. Alternately, an RS-232 cable can be attached to the RS-232 output on the case of the instrument. LED indicators located on the enclosure exterior identify the transmitter status.
 
The data logging software runs on a Windows™ PC and will display the radiation data just like a chart recorder and also log the radiation data. User-supplied GPS coordinates fed into the PC are captured and stored along with its corresponding radiological data into a comma delimited file. Ludlum also provides a KML (Keyhole Markup Language) software program that converts the data files into files suitable for viewing in Google Earth™ or any other 3D earth browser implementing the KML encoding.
 
The Geo-Explorer is available in different versions to best suit your requirements. Some choices include with and without a laptop computer, or with and without GPS. Contact Ludlum Measurements for more information.
