Major Tech 1000A AC/DC Trms Clamp Meter MT775

Description

High-Performance Testing You Can Rely On

The Major Tech MT775 delivers serious on-site capability for electricians who need fast, dependable readings under pressure. With True RMS accuracy and a wide measurement range up to 1000A AC/DC and 1000V AC/DC, it’s built to handle everything from everyday installation work to complex fault-finding in live systems.

The large 6000-count backlit LCD ensures clear visibility in any environment, while fast sampling helps you capture real-time changes without delays. Features like Inrush Current measurement and Peak Mode make it easier to diagnose motor starts, load spikes, and transient issues quickly—keeping troubleshooting efficient and precise.

Built for Compliance, Safety & Real-World Conditions

Rated CAT IV 600V and CAT III 1000V, the MT775 is designed with jobsite safety in mind for demanding electrical environments. Its double-moulded housing improves durability, giving you confidence when working in harsh trade conditions.

Advanced functions like LoZ (low impedance mode) help eliminate ghost voltage errors, while VFD mode ensures stable readings on variable frequency drive systems. Combined with NCV detection, continuity testing, and diode checks, this clamp meter supports safer decision-making on live circuits and complex installations.

Designed to Keep Trades Moving Faster

Built for efficiency, the MT775 helps reduce downtime with practical trade-focused features like data hold, min/max, relative mode, and auto power off. The integrated flashlight improves visibility in switchboards, ceilings, and dim work areas, while the 33mm jaw makes clamping onto larger cables quick and hassle-free.

Temperature, frequency, capacitance, and resistance measurement functions reduce the need to carry multiple instruments, streamlining your toolkit on busy jobs. With included accessories like test leads, Type-K probe, adaptor, and carry case, it’s ready to go straight out of the box.
