  • Wideband Measurement: Covers noise frequencies from 300kHz to 700kHz, addressing common powerline interference.
  • Real-Time Feedback:3.5-digit LCD Display: Shows noise intensity (higher value = stronger noise).
  • Built-in Speaker: Audibly amplifies detected noise (louder sound = higher noise level).
  • Adjustable Sensitivity: Fine-tune sensitivity (e.g., set to 100 as baseline) to compare noise levels before and after filtering.
  • Over-Range Alert: Red LED lights up when noise exceeds measurable range.
  • Anti-Slip Design: Rubber feet ensure stable placement during operation.
  • Input Voltage: 220~240VAC or 110~120VAC (selectable version)
  • Power Frequency: 50/60Hz
  • Power Consumption: 4W
  • Operating Conditions:Temperature: 13~33°C Altitude: ≤2000m
  • Dimensions & Weight:135mm (L) × 91mm (W) × 45mm (H) Weight: 310g (excluding power cable)
  • Standard Accessories:Main unit ×1Detachable 2-core AC power cable (0.8m) ×1

Operation Guide

  1. Plug the analyzer into an unfiltered power outlet and adjust the sensitivity knob until the reading reaches 100.
  2. Move it to a filtered outlet (e.g., surge protector/isolated power source) to observe noise reduction effects.

 Applications

  • Detecting high-frequency noise in household/industrial power lines.
  • Evaluating noise suppression performance of filters, isolation transformers, or UPS systems.
  • EMI testing during electronic device development.

1. What is the difference between the OLED Line EMI Meter and LCD Wideband Powerline Noise Analyzer?

Q: What does the OLED version measure?

A: The OLED version measures absolute noise values. It shows the actual ripple/noise level directly, which reflects the real electrical noise. However, noise reduction needs to be calculated manually.

Q: What does the LCD version measure?

A: The LCD version measures relative values. You can set a reference level (for example, 100), making it easy to instantly see the percentage of noise reduction. This is faster and more convenient for comparison.

Q: Which one should I choose?

A: Choose OLED if you want real, absolute noise measurements. Choose LCD if you prefer quick, intuitive comparisons and percentage-based results.
