Model Geologger-GWS 2 & GW -Combination Probe

A PC-based control part, a 10.4-inch LCD and data processing circuits are all stored in one compact case, giving this instrument superior operability and portability. Also, its data are in comma-separated value (CSV) format that can be edited on a PC easily.

• Natural gamma, resistivity (16”, 64”) and spontaneous potential can be measured at the same time just by one probe
• Data can be checked easily on its 10.4-inch high-intensity color LCD
• Data (CSV format) can be copied into a USB memory through its USB ports
• Compact, lightweight and low-power consumption design
