FNIRSI DMT-99 Smart Digital MultimeterThe 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 screen, 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 in the range of -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 provides up to 10 hours of operation, and True RMS, intelligent burnout protection, and DIY interface make it an indispensable tool for electricians, electronics engineers, and DIY enthusiasts.Crystal clear image – 2.4-inch HD TFT screenThe large, high-resolution TFT color display makes reading measurements extremely easy and comfortable. The rich color palette and clear digits eliminate eye strain during long periods of work. Even in low light or at 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 fussForget about turning the knob and wondering which mode to choose. The automatic recognition function identifies the measured parameter itself and selects the appropriate range. General mode supports all basic measurements, recording mode saves measurement curves and minimum and maximum values in real time, and monitor mode acts as an electronic guard – it warns you with a sound when the measurement exceeds or falls below the set threshold. This saves a lot of time and eliminates the risk of error.Record-breaking battery life – 10 hours of continuous operationThe 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, in the field, or in a workshop without worrying that the device will run out of battery at the least opportune moment. Charging via the USB-C connector is fast and convenient – you can charge the multimeter from a power bank, phone charger, or in your car.Precise True RMS measurements – true effective valueThe True RMS function allows you to measure the true effective value of AC voltage regardless of the waveform shape. Typical 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 gives you confidence that the result is accurate, which is crucial for professional diagnostics and repairs.Live wire and neutral wire detection (LIVE) and NCV – safety without touchingThe LIVE function allows you to use a single probe to detect which wire is live (phase) and which is neutral (zero). You don't need two probes or to connect to the installation – just bring the device close to the wire. In addition, the NCV (Non-Contact Voltage) function detects the presence of AC voltage in a cable or socket without the need for direct contact. An audible signal and a visual change in the magnetic field intensity on the screen (four levels: none, low, medium, high) indicate the presence of voltage. It is the perfect tool for checking whether a wire is safe before starting work.Temperature measurement from -55°C to 1300°C – from freezing to scorchingThe built-in thermometer function with a wide measuring range makes the DMT-99 a versatile tool. You can check the temperature of electronic components, heat sinks, motors, furnaces, soldering irons, and air conditioners. Instant access to temperature measurement eliminates the need to carry a separate pyrometer or thermometer – you have everything in one device.A full range of electrical measurements – all in one deviceThe multimeter measures AC and DC voltage, AC and DC current (up to 10A), resistance (10,000 counts), capaci
