SYSCAL R1 PLUS

SYSCAL R1 Plus

The Syscal R1 plus is designed for medium depth applications, featuring a powerful transmitter and 2 measuring channels in a compact design.

Data acquisition is fully automated with automatic self-potential correction and ranging, digital stacking for signal enhancement, and real time error display. The internal memory can store all required information (intensity, voltage, resistivity, chargeability, geometrical parameters and station number).

The Syscal R1 plus switch is equipped with switching cards that can efficiently operate 24 (Switch-24) up to 72 (Switch-72) electrodes rendering ideal for electrical resistivity imaging (ERI) applications.

For imaging applications, Iris Instruments proposes different standard heavy-duty multi-core cables (5 traces – 10m, 10 traces – 5m and 10 traces – 10m). Customized cables may also be assembled for special arrays or non-standard applications.
Measurement sequences can be configured through the instrument interface or via the PC software Electre Pro (provided with the Syscal). Electre Pro enables operators to develop and interrogate 2D, 3D, downhole and roll long sequences prior to heading into the field, helping to minimize potential data collection errors. The measured data can be downloaded and processed before inversion via the PC software (Prosys II, provided with the Syscal).
