LCD Wideband Powerline Noise Analyzer

• 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.
