Taoma electro-magnetic field monitoring instrument is an electric, magnetic and electromagnetic field analyser that is suitable for a wide range of applications. The Taoma electro-magnetic field analyser, available from Westek Electronics , is capable of measurements from 15Hz to 30MHz by switching probes that are supplied with this single instrument as standard.
The Taoma electro-magnetic field analyser has been used on applications such as the investigation of medium voltage power fields on the growth of soy seedlings (showing an average length increase in excess of 7% at field strength in the region of 2000V/m and higher) and the study of non-thermal effects on human subjects as a result of exposure to power line fields.
Numerical techniques and their associated computer programmes for the calculation of field characteristics can be a useful aid for designers of transmission lines and towers as well as for environmental protection authorities. Theoretical calculations were then contrasted against practical measurements in HV substations with the Taoma electro-magnetic field analyser.
In life sciences, investigations made include the effects of electromagnetic fields on polychromatic erythrocytes in bone marrow of mice and the influence on myelin shields of nerve fibres. The Taoma universal electro-magnetic field analyser incorporates the Microsoft ‘Windows’ CE.NET operating system, thus making the instrument suitable for data analysis in the field without requiring connection to a separate computer. Temperature and humidity sensors and a GPS module providing exact physical location of the measurements are provided as standard.
The Taoma electro-magnetic field analyser is available with an optional GPRS module permitting remote data transmission. Other standard interfaces supplied include RS232 (electrical or optical), USB, Ethernet (RJ-45), and SD card slot as well as a 0 to 5V scanning input.
The Taoma electro-magnetic field analyser has a data memory of 512MB thus allowing the on-board storage of up to 250 hours of measurement results. Results can be displayed as instantaneous, average, and maximum values or as amplitude-time variations. The Taoma electro-magnetic field analyser has a VGA 6.4 inch TFT display, alphanumerical keyboard with specific function access keys integrated navigational trackball.
The probes supplied as standard with the Taoma electro-magnetic field analyser include magnetic induction (B) from 15Hz to 100kHz, electric field (E) in the range of 15Hz to 100kHz, E fields in the range of 100kHz to 6GHz, E fields in the range of 3MHz to 18GHz and magnetic strength (H) fields in the range 300kHz to 30MHz.
The Tamoa electro-magnetic field analyser is a single instrument with a wide scope of applications by virtue of the bandwidth covered, thus making it useful for scientists in many disciplines as well as research and design engineers and technicians.
