The HHG191 Gauss Meter represents the latest design in magnetic measuring equipment, allowing
measurements up to 2000 mG to 200 micro-tesla with a basic accuracy of 2.5% plus 6-digit.
The HHG191 is capable of measuring the electromagnetic field radiation intensity that is produced from
electric transmission equipment, power line, microwave oven, air conditioner, refrigerator, computer monitor,
and video/audio device.
This meter is applied to measuring electromagnetic fields of extremely low frequency (ELF) of 30 to 300 Hz.
