Syscal Junior (Jr)
The Syscal Junior is an all-purpose resistivity imaging and sounding system. It features 2 measuring channels, allowing for the recording of two simultaneous measurements. The output current is automatically adjusted (automatic ranging) to optimize the input voltage values and ensure the best measurement quality. The system is designed to automatically perform pre-defined sets of resistivity measurements with roll-along capability.
Compact, easy-to-use and field proof, the Syscal Jr measures both resistivity and chargeability (IP). With a maximum power output of 100W at 800Vpp, the Syscal Jr is suitable for most near surface geophysical prospection applications, such as pollution monitoring, salinity control, depth-to-rock determination, weathered bedrock imaging and shallow groundwater exploration (depth and thickness of aquifers).
The Syscal Jr comes also in a switch version outfitted with internal switching capability for automated electrode switching [24 (Switch-24) 48 (Switch-48) or 72 (Switch-72)] significantly reducing acquisition time. Syscal Jr switch is recommended for electrical resistivity imaging (ERI) applications.
