MULTICHANNEL SEISMOGRAPH LAKKOLIT-MT
Multichannel seismograph Lakolit-MT is designed primarily for engineering applications and micro-zoning. One of the key advantages of Lakolit-MT is its modular concept, which provides the user with a flexible multi-channel seismic acquisition system. In this system, several telemetry units can be linked with the synchronization unit that controls the seismic system. Each telemetry unit includes a six-channel registration unit and a six-channel seismic cable with geophones.

The Lakolit‐MT is a multichannel seismograph for engineering applications and micro‐zoning surveying.
The Lakolit‐MT provides the user with a flexible multi‐channel seismic acquisition system. In this system, several telemetry units can be linked with the synchronization unit that controls the seismic system. Each telemetry unit includes a six‐channel registration unit and a six‐channel seismic cable with geophones. Using the Lakolit‐MT, a specialist can create and build a surveying system, including 3D data collection.
A laptop/control unit is used to control the seismographs.
The system has a robust casing, allowing it to function perfectly in extreme weather conditions.
FEATURES
•a Modular concept
•a Robust waterproof metal housing
•wireless communication
•remote start of recorders and a seismic vibration source simultaneously via radio channel
•operation with different synchronization system
•high‐quality data registration
THE LAKOLIT‐MT INCLUDES:
•a Six‐channel recorder for recording, digitizing and transmission seismic signals from geophones to the control unit or PC. The recorders can be linked with a six‐channel telemetric seismic cable with geophones;
•a Control unit or PC for controlling the seismographs' operating modes;
•a Synchronizer for:
•setting the same frequency for all recorders
•charging recorders from battery or external power sources
•starting the recording using synchronization channel - connecting the control unit or PC;
•a Radio triggering system (consisting of a transmitter and receiver) for remote start of the station synchronized via radio channel at a distance of up to 500 meters;
•three or Six‐channel telemetric seismic cable with 2, 5 or 10 meter channel;
•vertical and horizontal geophones.
