EMI Sniffer Mains Noise Analyzer Unboxing

Video includes testing of various mains filters.
10KHz-10MHz Line EMI Meter Mains Noise Analyzer EMI Measuring Device w/ OLED tps.
The main function of this AC mains noise tester is to display the current voltage and noise voltage of the mains through the panel's OLED dot matrix screen. In this way, everyone can see the current state of the mains power very intuitively, and have an accurate judgment on the quality of the power supply.

Features:
OLED screen displays noise voltage and AC voltage
There are small speakers that can directly amplify the noise output, and judge the noise intensity and frequency by sound
Plug directly into a wall socket (power socket)
The speaker plays EMI sounds and amplitudes are demodulated to identify EMI sources (such as AM or shortwave radios, motors and arcs)

Specifications:
Input voltage: AC 85Vac - 250Vac 50/60Hz (Accuracy: ±1 VAC)
Frequency Range: 10KHz - 10MHz
Noise Range: 1mV - 1999mV
Measurement Accuracy: ±5% @ 1MHZ; +5% to -50% @ 10 KHz to 10MHz
Noise Indication: 4 digits yellow and blue two-color OLED digital dot matrix display
Dimensions: 132 x 91 x 41mm
Machine weight: 150g

Package Included:
1 x Mains Noise Analyzer
1 x 0.8m AC Power Cable

What is a recommended EMI level?
Ideally, dirty electricity (EMI) levels should be below 25 millivolts (mV). Levels between 25 and 50 mV are marginal and should be reduced if possible. Levels above 50 mV are undesirable and steps should be taken to lower them.
