| UHS three-axis AC EMF meter from AlphaLabs (with an analog BNC output jack). This used to be my favorite meter until I got the MT-263. It features three settings for excellent resolution - under 20 mG, 200 mG, and 2,000 mG. It also has different frequency settings - from 13 to 1,000 hertz, and from 1 kHz to 75 kHz, or a combination of both frequency ranges. Psuedo-RMS measurements are only accurate for sine waves, so this can be a problem in the field, where you don't know what you're measuring. |
