OLED Line EMI Meter

Dual-Parameter Real-Time Display

• OLED dot-matrix screen clearly shows AC voltage (e.g., 126.1 mV) and noise voltage (e.g., 221 μV), enabling dynamic comparison before and after power conditioning.
• Noise Progress Bar: Length adjusts in real time with noise intensity—longer bars indicate stronger interference for quick assessment.

High-Frequency Noise Detection

• Specifically designed to measure 10KHz–10MHz high-frequency noise, covering common interference sources (e.g., AM/shortwave radio signals, motors, arcing).
• Note: Some filters may have limited suppression effects on this frequency range; test data should be evaluated comprehensively.

Acoustic Diagnostics

• Built-in speaker amplifies and outputs noise signals, helping users identify interference sources (e.g., radio signals or EMI from devices) via amplitude and frequency.

Convenient Power Supply

• Directly plugs into 220V/50Hz AC outlets—no batteries required. Includes a detachable 0.8m two-core power cord.
