The Major Tech MT878 is a multi-purpose tool that combines a stud and metal detector, live wire finder, and a fully functional auto-ranging multimeter. It’s great for locating studs behind walls, detecting both ferromagnetic and non-ferromagnetic metals, and identifying unshielded live AC wires. Multi-colour LEDs and an audible buzzer provide instant detection feedback, making it easy to use on-site.
As a true RMS multimeter, it measures AC/DC voltage, AC/DC current, resistance, continuity, capacitance, frequency, duty cycle, temperature, and diodes. It includes a LoZ setting to eliminate ghost voltages for more accurate readings. For high-current applications, it supports the MT783 clamp adaptor to extend measurement up to 400A AC/DC. The 4000-count backlit LCD with a bar graph ensures clear, real-time readings, and a tilt stand makes hands-free operation convenient.
Q: What is the maximum current measurement capacity?
A: The meter supports up to 400A AC/DC when used with the optional MT783 clamp adaptor.
Q: Can this meter detect live electrical wires?
A: Yes, it detects unshielded live AC wires up to 50mm deep.
Q: Does the meter include a backlit display?
A: Yes, it features a 4000-count backlit LCD with a bar graph for easy readability.
