Nanotesla Meter

RM100 - Macintyre Electronic Design Associa (MEDA)

The RM100 uses a differential measurement technique employing two subsystems to achieve its high accuracy. The first subsystem is a user controlled field neutralization unit with a dynamic range of ±100,000 nT and a resolution of 0.1 nT. The second is a low noise analog output magnetometer that measures the difference between the ambient and neutralization fields. The neutralizing field and difference field are displayed on a large Vacuum Florescent Display on the front panel. The difference field is also provided as an analog voltage through a connector on the back of the chassis. The factory calibration of the neutralization subsystem to ±0.01% is traceable to NIST.
