One & Three components
The compact broadband low-noise seismometer CME-4111 is well suited both for permanent
and portable installation.This easy-to-install, very rugged instrument does not require any
maintenance, mass locking and centering. The instrument offers the cost-effective solution for
installations with the noise level close to Low-Noise Model. The three-component (standard)
and one-component versions are available, as well as the version with the lowered
consumption (7.5 mA).
Broadband three-component seismometer CME-4011
The model CME-4011 is one & 3-component broadband seismometer well suited for rapid
deployment in arrays, monitoring of structures, and for permanent installation in locations
with the background noise higher than the New Low Noise Model. This easy-to-install, very
rugged instrument does not require any maintenance, mass locking and centering. This
model is ideal for portable applications, demanding the combination of high performance,
low power consumption, compact size and low-cost.
Short-period seismometer CME-3111
Economical compact size seismometer — the short-period analog of the model CME-4111
(available in one- and three-component configurations). The seismometer is characterized
by wide dynamic range, low self-noise, high gain, low power consumption. It's very reliable
and has no moving parts to be broken or wear out. Like other molecular-electronic
seismometers, this model has no demands on mass centering at installation and mass
locking for transportation.
The seismometer is well suited for portable and permanent installations in locations with the
background noise close to the Low Noise Model. It can be used in exploration seismology,
engineering geophysics, industrial vibration monitoring and many other applications.
Short-period seismometer CME-3011
Compact size and low cost sort-period seismometer with the high gain and wide dynamic
range. The device is available in uniaxial and triaxial configurations and adapted for portable
applications as well as for permanent installations in locations with the background noise
higher than the Low Noise Model, and well suited for university research and educational
centers.
The seismometer is very rugged, does not require any maintenance or mass locking and
centering. Maximum installation tilt is ± 15°.
3-component borehole seismometer CME-4111-BH150
borehole seismometer in waterproof case
The broadband low-noise three-component borehole molecular-electronic seismometer
CME-4111-BH150 is designed in strong waterproof case of stainless steel and can be
installed in flooded boreholes at depth 150 m under water. The device is very rugged and
does not require any maintenance, mass locking and centering. The external case is supplied
with waterproof cable connector and lifting ring. The instrument can be used at permanent
seismic stations and for portable applications.

Short-Period Seismometers
Ocean bottom and borehole seismometers
Off-shore broadband seismometers CME-4011-WP10 & CME-4111-
WP10
The models CME-4011-WP10 and CME-4111-WP10 are the ocean-bottom versions of the
broadband seismometers CME-4011/CME-4111 and have the same essential technical data.
The seismometers are supplied with the waterproof cases of strong plastic and stainless
steel, that allows its underwater installation down to 10 m depth.
The seismometers are very rugged and can be used both on sea bottom and on land.
Ocean-botton broadband seismometers CME-4011-OBS and CME-
4111-OBS
Seismometers CME-4011-OBS and CME-4111-OBS are specially adapted for ocean bottom
applications versions of models CME-4011 and CME-4111 correspondingly. These models
share main technical parameters with corresponding regular versions, but have a specially
designed compact lightweight case, flat flexible signal cable and consume less power.
Specially designed hardware allow the seismometers to be installed inside titanium or glass
waterproow spheres, usually used in ocean bottom installation. The instrument is fully
operable at up 15° tilt angle and thus does not require accurate leveling.
