Infiltec QM-4.5V-20HZ Seismometer detects nearby blasting, traffic, quakes

Description: QM-4.5V-20HZ Strong Motion Seismometer for Monitoring Ground Vibrations. The Infiltec QM-4.5V-20HZ compact strong-motion seismometer is designed for school, office, home and field use to detect and record nearby sources of ground vibrations such as blasting, machinery, traffic and nearby earthquakes. --> --> The Infiltec Model QM-4.5V-20HZ Seismometer is designed for school, office, home and field use. It records and displays vibration, shock, and PPV (Peak Particle Velocity) in a compact, portable, and rugged package that is less expensive and easier to use than conventional designs. The QM-4.5V-20HZ has an internal vertical geophone sensor and custom electronics to detect ground vibrations from nearby sources like blasting, machinery, traffic, and local earthquakes that are in the 4.5hz to 20Hz range. It will NOT detect most distant earthquakes because their predominant vibrations are generally at frequencies below 1 Hz. The QM-4.5V-20HZ does not require any external power supply or assembly or enclosure or adjustment; including alignment, damping, zeroing, etc. The QM-4.5V-20HZ works with the standard AmaSeis Windows XP/Vista/7/8/8.1/10 based seismic software. It also works with the new jAmaseis software for Windows, Linux and Mac OS. For distant earthquake detection, see our Model QM-4.5LV Seismometer.

Nothing else is required.10 second hardware setup! Take it out of the shipping box, plug it into your PC, and recording starts. (This assumes that AmaSeis software is installed and running) You can create your own online web page that displays your QM-4.5V-20HZ realtime display. Detects USA quakes with magnitude 6 or larger (approximate). Detects worldwide quakes with magnitude 7 or larger (approximate). Detects local quakes magnitude 3.5 within 60 miles or 100 km (approximate). --> Detects and records local blasting, machinery noise and traffic 24/7.PPV (Peak Particle Velocity) can be calculated from AmaSeis amplitude data display. Works with AmaSeis seismic Windows software, the seismic education standard. No assembly ever required. No damping adjustments ever required. No external power supply ever required. No complex leveling adjustments ever required (use bubble level to level once within +/-15 degrees). No additional enclosure ever required to protect against air currents No alignment ever required. No adjustments for moving ever required, just pick it up and move it. No adjustment of internal electronics (amplifier, filter, digitizer, power supply) ever required. Practically indestructible to damage caused by shock, vibration, shipping & handling. One enclosure contains everything: sensor, amplifier, filter, digitizer, power supply. Metal enclosure shields electronics against noise from nearby electromagnetic interference. High digital resolution (16 bits) keeps large and small vibrations on scale High-quality low-pass filter (Elliptic type) reduces sampling rate to 50 samples per second. Steep low-pass filter cutoff (8 pole) allows slower sampling output (50 sps) without aliasing. Zero-drift amplifier reduces low frequency (1/f) noise in the system bandwidth. Microprocessor firmware adjusts for component drift due to temperature changes, aging, etc. Very low power (under 0.05 Watts) operation supplied from RS232 lines. Designed to operate continuously 24/7/365. Connects to PC DB9 serial port, or a USB port through a USB-Serial DB9 adapter (included). Works on Windows XP/Vista/7/8/8.1/10 PC via AmaSeis logging data 24/7 in background. You can use your PC for other jobs while AmaSeis is running. Just keep the AmaSeis display full screen, even if in background. Installation: place on level, non-ferrous, ground contact slab away from foot traffic and machinery and rapidly changing temperatures. May not work well on wooden floors or upper building floors. The ideal location is an insulated vault on bedrock like this. NEW: Works with jAmaseis Java based software for Windows, Linux, and Mac OS. NEW: You can download the latest USB-Serial adapter Prolific drivers for Windows, Linux, and Mac OS. The label on the top of the enclosure has Quick Start Instructions.

HOW TO USE AMASEIS SOFTWARE ON YOUR PC WITH THE QM-4.5V-20HZ SEISMOMETER: Note that most of the extensive online Amaseis software instructional material references the AS1 seismometer setup that is not relevant to the QM-4.5V-20HZ, so skip the AS1 material and look for AmaSeis software setup and use instructions. Each QM-4.5V-20HZ Seismometer has Quick Start Instructions on a label on the top of its enclosure. Seismology Instruction with AmaSeis (pdf) from IRIS Seismographs in Schools Program.
