Macintyre Electronic Design Associates (MEDA), Inc., founded in 1980, manufactures instruments and sensors for measuring weak magnetic fields in the DC to 200 kHz frequency range. MEDA is located in Dulles, VA., a suburb of Washington, D.C.

MEDA was the pioneer in the development of a new generation of high sensitivity induction coil magnetometers that offer unsurpassed sensitivity, accuracy and wideband performance in the 0.1 Hz to 200 kHz frequency range.

In 1989 the company introduced the first handheld fluxgate magnetometer, the ?MAG, which measures DC to 400 Hz magnetic fields from 1 nT to 200,000 nT.

MEDA entered the satellite magnetometer market in 1994 when Schonstedt Instrument Company (SICO) terminated their satellite magnetometer business. Experienced personnel were added to MEDA from SICO, and a new facility was constructed which is dedicated to the production of these highly reliable instruments.

In 1998 the company introduced the first three-axis handheld fluxgate magnetometer, the FM300 Vector Magnetometer. This sophisticated instrument has a dynamic range of 100,000 nT and can be controlled remotely by a computer.

Market
The MEDA products can be divided into three market segments. The handheld instruments are used by engineers, scientists and technicians to evaluate shielding effectiveness, inspect packages, control the magnetic environment, determine magnetic properties of objects and measure magnetic signature of vehicles.

The satellite magnetometers are normally incorporated into attitude control systems. Customers for these products include all the major aerospace industry organizations.

The induction coil instruments and sensors are used to measure the electromagnetic environment in the extremely low frequency (ELF) to sub radio frequency band. Power line related fields and the magnetic fields generated by video display terminals are of particular interest.

Mission
MEDA's mission is to be the leader in low level magnetic field measuring instruments and sensors that provide accurate and reliable performance at a reasonable price.
