A user-friendly web interface, standard Ethernet, GPS-synchronised continuous recording to USB, and affordability have made the EchoPro the best-selling Kelunji seismograph in our 40 year history.
With 6-channels as standard, the EchoPro is ideal for monitoring weak and strong ground motions using a triaxial seismometer and accelerometer, particularly when specified with an internal triaxial MEMS accelerometer to take over when a external seismometer signal might clip.
Other options include: an LCD and keypad for limited setup of a 6-channel recorder, which can also display data graphically in real time; two types of internal battery providing 12+ and 24+ hour autonomy, supplied with matching chargers; and a ruggedised case with an internal LCD and keypad, and internal GPS aerial for daily monitoring surveys.
With differential voltage or constant current inputs, the EchoPro is compatible with all known seismometers, accelerometers, geophones, and microphones, with support for sensors manufactured by all the major suppliers, including Guralp, Nanometrics, Lennartz, and Sercel.
