Discover the reliable and versatile FNIRSI S1 multimeter for both home and professional use. It offers automatic measurement identification, True RMS, NCV voltage detection, a continuity test with audible alert, AC/DC voltage, resistance, frequency, and temperature measurements, and Smart Anti‑Burn protection. A clear VA HD display, built‑in flashlight, and a 1000 mAh rechargeable battery via USB‑C ensure convenience, safety, and long endurance.
The FNIRSI S1 is a smart digital multimeter designed for fast and accurate diagnostics in the workshop, at home, and in the field. Thanks to the auto range and HOLD function, you can focus on the task while the device shows readable results on the color VA display. The integrated chip and Smart Anti‑Burn provide full protection against overload and incorrect operation.
The multimeter handles a wide range of tasks: AC/DC voltage, resistance, frequency (Hz), NCV contactless detection with visual and audible indication, continuity test, diode test, phase and neutral wire check, and temperature measurement. A practical flashlight and power from a 1000 mAh lithium battery charged via USB‑C make work easier even in tougher conditions.
