JGS-3 Integrated Digital Logging System

Applications and Feature

• Integration of Acquisition Host Machine, Winch Controller and      Industrial Personal Computer (IPC) Large Screen LED Display

• For upward logging, also for downward logging

• Can receive digital / analog / pulse signal

• Winch automatically stops upon reaching the logging termination depth

• Automatic sampling as per depth interval, sampling interval      arbitrarily

• Indoor simulation logging, repeatability observation of instruments      and probes

• Integration of depth control system and data acquisition system

• Digital real-time display of frequency, voltage for supply voltage

• Real-time display of working voltage, working current for downhole      probe

• Membrane panel, attractive and durable

• Power Supply Current: 8 Stalls Optional

• Small-sized, Light in weight
