Digital Multimeter FNIRSI DMT-99
Overview

Description
FNIRSI DMT-99 is a 10,000-count intelligent digital multimeter with a wider measurement range and higher resolution, helping you measure more accurate values. It can accurately measure AC/DC voltage, AC/DC current, and can also be used to test conductivity, capacitance, frequency, duty cycle, resistance, diodes, temperature, NCV, live wires, and more.
It is suitable for various fields of electronic maintenance, including engineering, laboratories, automotive, and home appliances. The device is equipped with a 2.4-inch full-color TFT display with a resolution of 240 × 320 and supports a DIY boot interface. The new UI design and the first monitoring mode function enrich your user experience and make operation more convenient in various scenarios.
Features
- Recording Mode: the FNIRSI multimeter can plot the ripple of measured values that change over time, allowing observation of voltage or current fluctuations. Eight measured values can be recorded, and the maximum and minimum values are displayed
- Monitoring Mode: custom thresholds can be set in the multimeter’s monitoring mode, and a warning will be issued if the voltage exceeds or falls below the set threshold
- Power Efficiency: the built-in 1500 mAh rechargeable battery allows the multimeter to work longer. No more manually replacing bulky, hard-to-find disposable batteries; the Type-C port enables charging at any time
- Intelligent Mode: in intelligent mode, the DMT-99 digital multimeter can identify the measurement type and select the range with the best resolution, making measurements more convenient and faster, removing the guesswork for most applications
- Customizable Interface: the 2.4-inch full-color TFT display (240 x 320 resolution) makes it easy to use in dimly lit areas. It supports a DIY startup interface, allowing you to create your own personalized entry interface
- Versatile Multimeter: it measures AC/DC voltage and current and can test resistance, capacitance, continuity, diodes, NCV, and live wires. It is applicable for automotive, home appliances, and other electronic repairs
- Safety: the device features dual ceramic fuse protection
