SmartMag – the World's most advanced and portable magnetometer based on the Overhauser effect. The instrument is designed for precise measurement of magnetic field. SmartMag can be used as an observatory magnetometer, base station, or as part of a multi sensor gradiometer. It is fully compatible with MaxiMag console and can be used for any type of ground magnetic surveys.
Magnetometer for magnetic observatories
High sensitivity, sampling rate, and accuracy (less than 0.1 nT) make the SmartMag one of the best magnetometers for magnetic observatories. Real-time data upload is realized via USB, CAN FD or RS-232 connection. With the optional CAN-Ethernet interface SmartMag can be connected directly to network. The digital CAN FD cable can be up to several kilometers long. The device is supplied with the SmartManager software that has all the necessary functionality to perform observations in the INTERMAGNET network of magnetic observatories.
Multi-sensor gradiometer
SmartMag supports the ability to link through a CAN FD interface to create a synchronized distributed network of magnetometers. This unique feature allows flexible formation of multi-sensor gradiometers with the necessary measurement base. You can connect up to 30 SmartMags to the MaxiMag console or build a multi-sensor gradiometer with an almost unlimited number of sensors using CAN-Ethernet interface unit.
Internal or external GNSS receiver
Time and coordinates are provided by the internal multisystem GNSS receiver and additional possibility of connecting an external antenna. In some cases the connection of external GNSS receiver is required - SmartMag supports NMEA-0183 protocol and can be connected to navigation devices via RS-232 connection.
Easy-to-use portable console
SmartMag console is equipped with OLED display and a switch panel. The control of measured values and their quality is provided in digital, graphical, and audible modes. Data download is available via USB, RS-232 or from the built-in industrial microSD card. All our parts and connectors are non-magnetic, which allows SmartMag setup to be even smaller in size compared to other magnetometers.
Metrology - a guarantee of high accuracy
Every SmartMag is metrologically tested. We control the standard deviation of random error (noise), absolute accuracy and orientation error. All magnetometers are delivered with a certificate of calibration performed on a certified measure of magnetic induction. Metrological tests guarantee the accuracy and reliability of the measured data.
Reliability and warranty
Our R&D specialists have extensive experience in performing geophysical surveys. We are well aware that such equipment must be reliable, and the service must be fast and convenient. We give 3 years warranty on all our magnetometers, and our technical support will promptly answer any of your questions. Our Overhauser sensors have the longest in the World lifecycle of more than 10 years. If you are still working with outdated magnetometers - take advantage of our trade-in offer and protect your projects from potential problems.
