A 3-in-1 field-strength meter that simultaneously reads magnetic field, electric field and RF/radio-frequency strength using triple-axis (X/Y/Z) sensors, so a single sweep captures readings regardless of source orientation. Results appear on a color TFT screen as live numeric values plus bar and trend graphs, with data-hold, min/max capture, an audible alarm, and auto shut-off, running on 3 AAA batteries in a compact handheld body.
