The Zoyi ZT219 True RMS Digital Multimeter is a high-precision measuring instrument designed for professionals and electronics enthusiasts. It provides accurate readings of AC/DC voltage, current, resistance, capacitance, frequency, and more. With its True RMS (TRMS) technology, it delivers precise measurements even for non-sinusoidal AC waveforms, making it ideal for complex electrical environments.

Key Features:

✅ True RMS Measurement – Ensures accurate AC voltage and current readings, even for distorted waveforms.
✅ AC/DC Voltage & Current – Measures a wide range of voltages and currents with high precision.
✅ Auto-Ranging – Automatically selects the appropriate range for accurate results.
✅ Resistance & Capacitance Testing – Ideal for testing resistors, capacitors, and circuit continuity.
✅ Frequency & Duty Cycle Measurement – Useful for diagnosing frequency-dependent components.
✅ NCV (Non-Contact Voltage Detection) – Detects live wires without direct contact.
✅ Diode & Continuity Testing – Includes a buzzer for continuity checks.
✅ Data Hold & Backlight Display – Freezes measurements and improves visibility in low-light conditions.
✅ Auto Power-Off – Saves battery by shutting down after inactivity.
✅ Flashlight Feature – Built-in LED flashlight for working in dark environments.
✅ Overload Protection – Ensures safety while measuring high voltages or currents.
