Description

Keeping up with the 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 CME-6211 seismometer does not require mass centering or any other special techniques during installations. This model is designed for use mostly as a part of permanent seismic stations and is the ultimate one among our seismometers.
