LEMI-120

 

INDUCTION MAGNETOMETER FOR 
GEOPHYSICAL APPLICATIONS LEMI-120

Main features

Wide frequency dynamic range 0.0001 - 1000 Hz
Very low noise 
Low power consumption
Watertight housing
Weight 6 kg
Dimensions: diameter 75 mm, length  1350 mm

LEMI-120 features extremely low noise and frequency dynamic range and that makes it the perfect choice for a major variety of geophysical applications. State of art built-in modulator-demodulator preamplifier with low power consumption and differential output ensures that the sensor may be used with any recording system as far as 200 meters away from the sensor installation site. It is waterproof, rugged and ready for use right after switching on.
