The LHY OLED Line EMI Meter is a professional electromagnetic interference detection instrument designed to monitor electromagnetic noise in the frequency range of 10 kHz to 10 MHz on 240 VAC 50 Hz power outlets. Its built-in speaker projects amplified and demodulated AM/FM noise from the power line in real time, providing an intuitive reflection of power quality. This device quickly identifies power cleanliness, assisting both household and commercial users (particularly those with audio systems) in ensuring a pure electrical environment, thereby enhancing audio equipment performance. It is recommended to test the power line before configuring high-sensitivity audio systems to guarantee optimal sound output.

Features

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.

    Specifications

      • Input Voltage: 85V–250V AC (50/60Hz, ±5%–10% tolerance)
      • Measurement Range: 1mV–1999mV noise voltage
      • Accuracy: ±5%@1MHz; ±5% to −50%@10KHz–10MHz
      • Display: 4-digit yellow/blue dual-color OLED screen
      • Dimensions/Weight: 132×91×41mm / 150g

      Support

      Plug the test lead (AC power cord) into the power source. The meter will display noise in millivolts AC. Let the meter remain plugged in for at least 30 secondsto stabilize the readings.

      General guidelines:

      <50mV: Excellent

      <100mV: Very good

      <800mV: Good

      <1000mV: Average

      <1500mV: Poor

      Operation conditions:

      • Indoor use only
      • Operating temperature 28∘C±10∘C
      • Humidity 0 to 90% non-condensing
      • Altitude up to 2,000 meters
