ASMET-2 series Broadband Seismometers
|
• 5000 V/(m/sec) sensitivity;
• Flat response between 50 s and 20 Hz;
• No moving mechanical parts;
• Easy maintenance and installation;
• Low-noise
ASMET-2x is a low-noise, extended frequency band "Amateur Seismometer" model. ASMET-2V is one(vertical)-component and AS-23 is a three-component version. High gain sensor output is optimized for using with a non-expensive 12 to 16 bit resolution digitizer. This instrument has 10 dB better resolution than ASMET-2x instrument.
