OLED Mains Noise Tester EMI Tester Broadband AC Power Supply Ripple Analyzer

Description:The degree of influence of the quality of household AC power on the sound, I believe that the majority of audiophiles have a deep understanding, pay more and more attention to the quality of the power supply, to upgrade the power processor, power filter, isolated Is, the power of the power, and AC mains noise tester.The main function of this AC mains noise tester is to display the current-voltage value and noise voltage value 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.Feature:1. OLED screen displays noise voltage value and AC voltage value2. There are small speakers that can directly amplify the noise output, and judge the noise intensity and frequency by sound.3. Plug directly into a wall outlet (power outlet), no battery required;4. The speaker plays EMI sounds and amplitudes are demodulated to identify EMI sources (such as AM or shortwave radios, motors and arcs).Specification:Input voltage: AC 85Vac - 250Vac 50/60Hz (accuracy +/- 1 VAC)Frequency range: 10KHz - 10MHzNoise range: 1mV - 1999mVMeasurement accuracy: +/- 5% @ 1MHZ; +5% to -50% @ 10 KHz TO 10MHzNoise indication: 4 digits yellow and blue two-color OLED digital dot matrix displayDimensions: 132 X 91 X 41mmMachine weight: 150gRandom accessories: AC detachable two-core power cord, length 0.8 mPackage included:1X OLED noise tester
