2024年12月18日 · The companion app for your purchased DUALEM geosensing equipment. This app controls and reads data from the DUALEM sensor.

Electromagnetic induction (EMI) is an effective technique for measuring electrical properties but, in general, is complex in operation and interpretation. Compact devices greatly simplify EMI, in that they are most portable and operate typically at low induction number (LIN).

The DUALEM-4S is the sensor of the DUALEM-4, and it is available separately at lower price for integration with the user’s own surveying systems. DUALEM instruments (e.g. the DUALEM-1) incorporate a DUALEM sensor as well as an internal WAAS-enabled GPS receiver, a hand-held weatherproof display/keypad/power-supply, a carrying harness and ...

DUALEM instruments are calibrated precisely and permanently at the factory using a patented technique, eliminating problematic ad hoc calibrations in the field. Precise calibration, base-level stability, high sensitivity and advanced digital signal processing give the …
