LEMI-120. Frequency Response and Noise Level

 

LEMI-120 features extremely low noise and wide frequency dynamic range what makes it the perfect choice for a major variety of geophysical applications. The original 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, ruggerized and ready for use right after switching on.
