The Syscal Junior is an all-purpose resistivity imaging and sounding system for environmental applications. The system can be supplied as a standard imaging system capable of recording two measurements simultaneously. The second recording channel significantly improves data acquisition time when the instrument is fitted with internal switching board for 24 (Switch-24) 48 (Switch-48) or 72 (Switch-72) electrodes for Electrical Resistivity Tomography (ERT).

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 Switch measures both resistivity and chargeability (IP). With a maximum power output of 100W at 800Vpp, the Syscal Junior 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). In high resistance environment, it may be necessary to use the Syscal R1 plus.
