MicroMag PC based magnetic field meter

MicroMag USB Gauss Meter

DC Magnetometer for Your PC

Whether you need low cost, compact design, small probe head, or extensive data logging, MicroMag has it all. Completely auto ranging form 1G to 19,999G with 1G resolution and 10% accuracy. You can even adjust the sampling rate from 4 times per second to anything slower.

Three foot cable terminates in a tiny sensor which can easily fit in a .060 inch (1.5 mm) gap. The sensor tip can be bent if required for a variety of situations. Place the sensor on a magnet face to measure the field. With a resolution of 1 Gauss, it can measure small variations from magnet to magnet or it can detect if a given magnet has lost strength. Plug the unit into your Windows PC USB port to begin reading and recording fields (updates up to 4 times per second). Minimal setup required. No batteries needed, powered by USB port.

Build Your Own Gaussmeter

Want parts to build your own gaussmeter" Here is an AC magnetic field probe. It generates an AC voltage when exposed to AC magnetic fields. Although we do not know how the output from this unit varies with frequency, we do know that the greater the magnetic field, the higher the voltage generated (at 60 Hz, it produces about 1 mV per 20 mG). It can be connected to a DMM, analog voltmeter, oscilloscope, Audio Amplifier (see below), or recording device. Connect 3 of them in series and create a 3-axis unit. It is quite small: only 0.7" long x 0.7" diameter, with a removable rubber suction cup attached. Has 36" lead and 1/8" (3.5 mm) mono plug.

Turn your Digital Multimeter into a Low Cost RF Meter!


For RF Measurements Close to the Source Near Field Antenna

Can be used with 6 GHz Basic RF Meter or High Frequency Meter (or other RF meter with SMA connection) to measure the magnetic field component of the signal in the near field (up close to the source of radiation). Useful from 1 MHz to 7 GHz with a high gain averaging 30 dB. Great for checking cell phones, wifi, DECT, Blue Tooth and more. Also useful for checking the near field shielding effectiveness of your shielding items (such as cell phone shields). SMA connector, 50 Ohm impedence. Meter not included.

Works well with: (may need adapter)
- 6 GHz Basic RF meter
- RF Explorer
- High Frequency Meter
