Professional True RMS AC/DC Multimeter – Voltage, Current, Resistance and NCV Tester

Description

The DMT99 multimeter sets a new standard among digital testers, bringing together versatility, accuracy and ease of use in a portable, rugged package.
Designed for professionals and DIY enthusiasts alike, this tester stands out for the way it adapts to many different jobs: household maintenance, work on appliances, vehicle diagnostics, laboratories and electronics repair.

Thanks to the 2.4″ colour TFT screen with 240 × 320 resolution, every reading is clear and easy to see, even in poor light. The intuitive interface and easy-to-reach buttons let you switch quickly between measuring modes — with no complicated menus to work through.

The DMT99 measures AC/DC voltage up to 750 V (AC) or 999.9 V (DC), AC/DC current up to 9.999 A, resistance up to 99.99 MΩ and capacitance up to 99.99 mF. It also offers continuity and diode testing, non-contact voltage detection (NCV), frequency (up to 9.999 MHz), temperature measurement and live-wire detection, making it an exceptionally complete instrument.

The meter also features True RMS technology, which delivers accurate readings on non-sinusoidal waveforms too — essential when working on modern installations or on equipment with variable-frequency supplies.

One feature that makes it genuinely practical is the 1500 mAh rechargeable battery: no more disposable cells, and the convenience of USB Type-C charging. It also supports “monitor” and “record” modes, handy for tracking changes over time — perfect for testing power supplies, batteries, live circuits or for long-term logging.

The DMT99 is compact (≈ 185 g), easy to carry, tough and ready to work: a true all-in-one for every situation where you need fast, accurate, dependable readings.
If you are looking for a multimeter that combines professional performance, simplicity and versatility, the DMT99 is the one to pick.

Smart True RMS Digital Multimeter with Colour Display

Smart High-Accuracy Detection

An automatic recognition function measures voltage, resistance and diodes without changing mode.
A fast, accurate system that simplifies technical work and speeds up every electronic diagnosis.

Three Advanced Measuring Modes

Three operating modes for every need: general mode for fast automatic readings, record mode for analysis over time, and monitor mode with threshold alarms for continuous watch over electrical parameters.

Non-Contact Voltage Detection (NCV)

The NCV function detects the presence of AC voltage without direct contact, making checks safer.
The strength of the electromagnetic field is shown on screen and by a rising audible signal.

Live and Neutral Identification – Live Zero Wire

The Live Zero Fire function identifies live and neutral quickly with a single probe.
Ideal for fast, safe electrical jobs, it removes the risk of wrong connections during installation and maintenance.

Complete Electrical Measurements in Real Time

The measuring screen shows every key electrical parameter clearly and at a glance:
AC/DC voltage, current, resistance, capacitance, frequency, temperature, diode test, continuity, live/neutral detection and NCV voltage.
Everything you need for fast, reliable fault-finding in a single instrument.

High-Accuracy True RMS Measurement

True RMS technology guarantees a correct reading of the real effective value even on non-sinusoidal waveforms.
Unlike conventional multimeters, it delivers accurate results on complex signals, sharply reducing measurement errors in professional and industrial work.

Full Overload Protection with Fuses

The multimeter has an advanced overload protection system built on smart anti-burn chips and twin ceramic fuses.
This design reduces the risk of accidental damage when a measurement is set up wrongly, improving operator safety and the reliability of the instrument in professional use.

USB-C Charging and Rugged Bench-Grade Design

The multimeter has Type-C charging, a rear clip for the test leads and a folding stand for convenient use on the bench or on a wall.
The shock-resistant ABS case gives it strength and reliability even in demanding workplaces, making it ideal for maintenance, installation and everyday professional use.

1500 mAh Rechargeable Battery with Up to 10 Hours of Use

The multimeter has a built-in 1500 mAh lithium battery, designed to give up to 10 hours of continuous use.
Ideal for long working sessions, it removes the need to change batteries often and keeps you working in the lab and out in the field.
