QM-4.5LV Seismometer for School, Office & Home.

The Infiltec Model QM-4.5LV Seismometer is designed for school, office, field, and home use. It provides worldwide earthquake detection 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 seismic geophone sensor and custom electronics to detect seismic signals from local and worldwide earthquakes. The QM-4.5LV does not require any power supply or assembly or enclosure or adustment; including alignment, damping, zeroing, etc. The QM-4.5LV works with the standard AmaSeis Windows based software, and its sensitivity is similar to the standard educational AS1 seismometer.

• Performance: Earthquake sensitivity similar to the standard educational AS1 seismometer - generally magnitude 6 or greater in the USA, 7 or greater worldwide.
• Mode of Operation: Single-axis, vertical velocity sensing by digitizing the amplified and filtered voltage from a vertical geophone sensor.
• Output: Serial output formatted for AmaSeis seismic software, RS232 9600 baud N81 ASCII.
• Frequency Pass-Band: 0.01 Hz to 1.0 Hz digitized and stored on hard drive by AmaSeis at about 1 megabyte per 24 hours.
• Temperature Range 40 to 90 F (4 to 32 C) with no adjustments required. Internal firware automatically adjusts for drifts.
• Housing: Diecast aluminum box encloses all electronics and sensor, 6.024x3.268x1.988 inches (153x83x50.5 mm). Shipping weight 2.2 lb (1 kg).
• Computer Connection: 10 ft (3M) serial cable (up to 100 ft (30M) extension optional) connects to PC DB9 connector or USB-Serial DB9 adapter.
• Adjustments: No leveling, alignment, damping, gain, zeroing, etc adjustments required.
• Power Supply: No external power supply required, all power supplied by PC serial port through the serial cable connected to the PC.
• Digital Processing: 16 bits voltage resolution from internal digitizer, 9 sample/second ASCII output, firmware adjusts for component drifts.
• Lowpass Filter: Analog 8 Pole Bessel filter @ 1 Hz corner frequency.
• Software: PC seismic data logging and analysis software AmaSeis available online for free download.
• Computer Requirements:PC running Windows (98/XP/V/7) can run AmaSeis in backgound while doing other tasks. Hard drive that can store 1 megabyte/day.

• 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)
• Detects USA quakes with magnitude 6 or larger (approximate).
• Detects worldwide quakes with magnitude 7 or larger (approximate).
• 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. Designed to operate continuously 24/7.
• Connects to PC DB9 serial port, or a USB port through a USB-Serial DB9 adapter.
• Works on Windows 98/XP/Vista/7 PC via AmaSeis logging data 24/7 in background. You can use your PC for other jobs while AmaSeis is running.

• You can pay by check, money order, credit card, bank wire transfer, or PayPal.

  To start recording, all you need is to download the Amaseis software and plug the QM-4.5 serial cable into your PC serial port with DB9 connector.

  OPTIONS: You may want to consider a serial (DB9 M/F) extension cable if you want to locate the QM-4.5LV a long way from the PC that is running AmaSeis to log data. The QM-4.5LV come with a 15 ft (4M) long serial cable, and the optional serial extension cables are 15 ft, 25 ft, 50 ft, and 100 ft long. Another option is a USB-Serial DB9 adapter cable for use with PC that do not have a physical serial DB9 connector.

  __SHIPPING
  1 Shipping within USA by USPS Priority Mail with insurance and tracking, per seismometer @ INCLUDED
  1 Shipping outside USA by USPS Air Mail with NO INSURANCE OR TRACKING, 5-10 days + customs processing time, per seismometer @ $60
  1 Shipping outside USA by UPS or FEDEX Air Mail with insurance and tracking, 3-5 days including customs processing time, per seismometer @ $160
  Note: for shipping to Russia, Kazakhstan, Belarus or Ukraine, consider setting up an account with QWINTRY AIR and using our "within USA" shipping option.

  Note that US Postal System (USPS) air mail overseas takes 5-10 days to reach your destination, but the customs processing in your country can take additional days or weeks. USPS air mail DOES NOT provide tracking or insurance after the package leaves the USA. In our experience, USPS air mail can be slow but we have never lost a package. UPS and FEDEX are much more expensive but they expedite customs processing so that overseas packages are delivered to you within about 5 days, and have tracking and insurance.
