Product Overview:
This LCD digital display wide-range AC power supply noise tester is a professional power quality analysis tool, primarily used to check high-frequency noise and ripple interference in mains power (220V or 110V). The instrument uses a 3.5-digit black and white LCD display to clearly and intuitively display measurement results, and has a built-in speaker to play back the checked noise in real time, helping users quickly diagnose power problems. It is widely used in power systems, industrial equipment, laboratories, and home power environments for power quality monitoring.
Features:
1. Wide-Range Measurement Range: Supports noise checked within the 300kHz-700kHz frequency range, accurately capturing high-frequency interference signals in mains power.
2. Dual Voltage Compatibility: Depending on the version, 220Vac~240Vac or 110Vac~120Vac inputs are available to adapt to different regional power standards.
3. Real-time noise playback: Built-in speaker amplifies and plays checked noise, allowing users to intuitively diagnose power problems through hearing.
4. High-precision digital display: 3.5-digit LCD monochrome screen provides clear display and easy data reading.
5. Portable design: Compact size (135mm × 91mm × 45mm), weighing only 310g, easy to carry and suitable for field operations.
6. Wide range of applications: Suitable for power quality analysis and EMI measurement in industrial equipment, laboratories, offices, and home power environments.
