The FNIRSI DMT-99 digital multimeter is an advanced measuring tool that combines the accuracy of professional equipment with modern technological solutions. Equipped with a 2.4-inch TFT HD color display, it supports automatic parameter recognition, data logging and monitoring mode with audible notifications. It offers a wide range of measurements: AC/DC voltage, current, resistance, capacitance, frequency, temperature from -55°C to 1300°C, neutral and phase wire detection (LIVE), NCV induced voltage detection and diode test. Powered by a built-in 1500 mAh lithium battery, it works for up to 10 hours, and True RMS, smart burnout protection and DIY interface make it an indispensable tool for electricians, electronics engineers.

Crystal clear image – 2.4 inch HD TFT display

A large, high-resolution TFT color display makes reading measurements extremely easy and comfortable. The rich color palette and clear digits eliminate eye fatigue during long work. Even in low light or when viewed from an angle, you can see every detail – no need to squint or use a flashlight to read the measurement result.

Automatic recognition and three operating modes – measure without hassle

Forget about turning the knob and wondering which mode to choose. The automatic recognition function automatically recognizes the measured parameter and selects the appropriate range. The general mode supports all basic measurements, the recording mode saves measurement curves and minimum and maximum values in real time, and the monitoring mode acts as an electronic protection – it warns with an audio signal when the measurement exceeds or falls below the set limit. This saves a lot of time and eliminates the risk of errors.

Record-breaking battery life – 10 hours of continuous operation

The built-in 1500 mAh lithium battery provides up to 10 hours of intensive operation on a single charge. You can work all day on a construction site, outdoors or in the workshop without worrying that the device will run out of power at the most inopportune moment. Charging via USB-C is fast and convenient – you can charge the multimeter from an external battery, phone charger or in the car.

Accurate True RMS Measurements – True RMS

The True RMS function allows you to measure the true effective value of AC voltage, regardless of the waveform. Conventional multimeters can show large errors when measuring distorted, non-sinusoidal signals – PWM generators, switching power supplies, inverters or power tools can be misleading. The DMT-99 with True RMS function gives you confidence that the result is accurate, which is very important for professional diagnostics and repairs.

Phase and neutral wire detection (LIVE) and NCV – safety without contact

The “LIVE” function allows you to use one probe to determine which wire is phase and which is zero (zero). You do not need two probes or to connect to the installation – just bring the device closer to the wire. In addition, the NCV (non-contact voltage) function detects the presence of AC voltage in the cable or socket without direct contact. An audible signal and a visual change in the magnetic field intensity on the display (four levels: none, low, medium, high) indicate the presence of voltage. This is a great tool to check if the wire is safe before starting work.

Temperature measurement from -55°C to 1300°C - from zero to hot

The integrated thermometer function with a wide measurement range makes the DMT-99 a versatile tool. You can check the temperature of electronic components, radiators, motors, ovens, soldering irons and air conditioners. Instant access to temperature measurement eliminates the need to carry a separate pyrometer or thermometer - everything is in one device.

The full range of electrical measurements - all in one device

The multimeter measures AC and DC voltage, AC and DC current (up to 10 A), resistance (10,000 readings), capacitor capacitance, signal frequency and checks diodes and circuit continuity (with audible signal). It is a full-fledged diagnostic center in your pocket - you do not need separate ammeters, ohmmeters or capacitance meters. You can read all parameters with one device, which speeds up your work and reduces the amount of equipment you have to carry with you.

Smart burnout protection - work safely

The integrated burnout protection system protects the device from damage in case of incorrect connection or exceeding the measurement range. 10A MAX FUSED fuses protect the current inputs, and the smart electronic system monitors the measurement parameters. Even if you make a connection error, the multimeter will not burn out - this saves a lot of money on repairs and gives you peace of mind when working.

HOLD function - save important measurements

The HOLD/REL button fixes the current reading on the screen so that you can calmly write down the result, take a picture or compare it with other measurements. You do not need to rush the readings or keep the probes connected longer than necessary. The data logging function allows you to record a series of measurements and analyze them later - ideal for documenting maintenance work or quality control.

Robust construction and thoughtful details - durability for years to come

The ABS plastic housing is resistant to drops, dust and moisture. Reinforced corners absorb shocks, protecting the sensitive electronic components inside. The folding stand on the back allows you to place the multimeter at a convenient angle on a table or in a cabinet. A belt clip makes it convenient to carry, and a hook on the back of the case allows you to hang the device on a nail or hook in the workshop. The USB-C charging port is universal and convenient - one cable for all devices.

Personalized interface and automatic shutdown - a tool tailored specifically to you

The DIY Boot Interface function allows advanced users to create their own personal interfaces and measurement functions. You can customize the screen layout, add custom measurement modes or expand the device's functionality to suit your needs. Auto power off saves battery power when you forget to turn off the device. It's an open approach to a tool that grows with your skills and requirements - an investment that won't age. Whether you're a professional electrician, maintenance technician, DIY enthusiast or hobbyist, the DMT-99 will meet your expectations.
