Infiltec QM-4.5LV Seismograph, Seismometer, earthquake detector, seismic monitor

Description: QM-4.5LV Seismometer for School, Office & Home. The Infiltec QM-4.5LV compact seismograph is designed for school, office and home use to detect earthquakes worldwide. --> --> The Infiltec Model QM-4.5LV Seismometer is designed for school, office, field, and home use. It records and displays worldwide earthquakes in a compact, portable, and rugged package that is less expensive and easier to use than conventional designs. The QM-4.5LV has an internal vertical geophone sensor and custom electronics to detect seismic signals from local and worldwide earthquakes. The QM-4.5LV does not require any external power supply or assembly or enclosure or adjustment; including alignment, damping, zeroing, etc. The QM-4.5LV works with the standard AmaSeis Windows XP/V/7/8/8.1/10 based software, and its sensitivity is similar to the standard educational AS1 seismometer. It also works with the new jAmaseis software for Windows, Linux and Mac OS. The QM-4.5LV can measure PPV (Peak Particle Velocity), but if you want to monitor vibrations from nearby blasting, machinery, traffic, etc. that are at higher frequencies than distant earthquakes, then you may want to consider a higher-frequency strong-motion seismometer like our QM-4.5V-20HZ Strong Motion 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-4.5LV real-time 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 local blasting, machinery noise and traffic.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 leveling adjustments ever required. 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 quakes on scale High-quality low-pass filter (Bessel type) preserves differences between seismic time delays. Steep low-pass filter cutoff (8 pole) allows slow sampling output (9 sps) without aliasing. Zero-drift amplifier reduces low frequency (1/f) noise in the system (0.01 to 1.0 Hz) 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. 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 Prolific USB-Serial adapter scroll down for 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-4.5LV SEISMOMETER: Note that most of the extensive online Amaseis software instructional material references the AS1 seismometer that is no longer available. The QM-4.5 LV offers comparable performance. Each QM-4.5LV Seismometer has Quick Start Instructions on a label on the top of its enclosure.
