The three-component wideband seismometer adopts advanced seismic sensor technology and is capable of simultaneously output analog signals and status parameters. The instrument features a durable and corrosion-resistant stainless steel casing. The connectors and hooks are located at the top of the instrument, facilitating installation in shallow Wells.
It is suitable for installation in submarine seismometers as an instrument for submarine seismic observation, meeting the high requirements of submarine seismometers for the inclination redundancy and frequency band of the seismometers used.
Characteristics
The Certis is a compact and portable three-component wideband seismometer with dimensions of only 80 mm x 80 x 112 mm
Advanced seismic sensors allow for full-range operation within a wide tilt range of ±90° by automatically aligning with the mass center.
Three-axis (ZNE) vertical orthogonality, cross-axis suppression (> 65 dB)
Users can remotely set the low-frequency end: 1s, 10s, 20s, 30s, 45s, 60s, 90s, 100s and 120s
Serial output can provide information such as the instrument serial number, frequency response and calibration parameters
The connector and lifting ring are located at the top of the instrument housing, which is very suitable for installation in shallow Wells
