MT87 digital AC clamp meter — 400A AC current, 600V AC/DC, resistance, diode, continuity LDR sensor 3V and 5V digital systemsThe MT87 is a compact digital AC clamp meter built on large scale integration (LSI) technology, offering a practical all in one measurement tool for electricians, engineers, and electronics hobbyists. It measures AC current non invasively via its jaw clamp no need to break the circuit along with AC and DC voltage, resistance, diode forward voltage, and audible continuity testing in a single handheld instrument.
