FNIRSI DMT-99 is an advanced digital multimeter with a 2.4" color TFT HD display, offering automatic detection of the measured quantity, True RMS, and wide measurement capabilities including AC/DC voltage and current, resistance, capacitance, frequency, and temperature (-55 to 1300 °C). It also features NCV non-contact voltage detection, phase (LIVE) identification, value storage/hold, and up to 10 hours of battery life thanks to a 1500 mAh battery charged via USB-C.
The FNIRSI DMT-99 smart multimeter combines professional measurement accuracy with modern features for faster and safer work. The large 2.4" TFT HD display ensures excellent readability even in poor lighting, and the automatic mode saves time—the meter recognizes the parameter being measured and selects the appropriate range.
For more demanding diagnostics, it includes True RMS (accurate AC RMS measurement even for non-sinusoidal signals), HOLD/REL to freeze readings and measure relative values, and logging options. The monitoring mode can also sound an audible alert if a value exceeds a set limit. In practice, you’ll also appreciate NCV (non-contact AC voltage detection) and LIVE identification of live and neutral conductors.
Main advantages and features:
- Automatic detection of the measured quantity and range
- 3 modes: standard measurement, recording (min/max and trend), monitoring with alarm
- NCV non-contact voltage detection + audible indication
- LIVE phase/neutral identification with a single probe
- Wide measurement functions: voltage, current (up to 10 A), resistance, capacitance, frequency, temperature, diode test, continuity (beeper)
- USB-C charging and built-in 1500 mAh battery with up to 10 hours runtime
- Durable ABS body, fold-out stand, and practical features for field work
