Geologger-GWS

Advanced Portable Logging Equipment

Geologger-GWS has been designed logging unit for ground water survey investigation
The probe supported is GW combination probe (model-3493).
The system has been kept low in cost, thus giving better value to the user.
This system adopted all in one system i.e. it incorporates advance feature such a 24 bit Delta Sigma converter, LCD display, high resolution printer and USB ports are available for USB memory stick.

● Borehole logging function for ground water development (16”, 64 inch normal, Natural gamma, SP).

● 24 bit Delta-Sigma A/D converter

● High resolution thermal printer

● Interface for memory storage. USB 2 ports / RS232C
