Seismometer CME-6211

Keeping up with parameters of CME-6111, the CME-6211 model has a significantly lower sensitivity toward the atmospheric pressure and temperature variations in a lower frequency range. 

This model's sensors are equipped with a double-shielded isolation from unwanted external actions. The seismometer does not require mass centering or any other special techniques during installations. However, this model has been designed for using mostly as a part of permanent seismic stations and is the most ultimate among our product line.
