2 in 1 AC voltage frequency meter - can automatically detect and display the accurate real-time voltage V and frequency Hz simultaneously. Universial volt Hz monitor - wide voltage measuring range AC 80-500V frequency measuring range 45-65Hz high working efficiency of 2 timess measuring speed. Sensitive digital LED screen display - the small voltage dectector with a upgrade clear and bright LED display, better than LCD Low working power consumption. Easy to use - 2 wires design, just connect directly with your device, it can test automatically, without extra power supply can embedded buckle installation, more stable. Multifunctional application - Only suitable for Pure AC45-65Hz mains supply, can't be used for measuring circuit of square wave, inverter output and sine wave. It can't be used for measuring the AC power converted from a DC power with an inverter perfect for different modes of gasoline engine generator, diesel engine generator, motor and RV.

2 in 1 meter which can measure AC voltage and frequency simultaneously, with potentiometer for frequency calibration, turn the screw clockwise to increase frequency and turn the screw anticlockwise to reduce the frequency.. It can directly connect two wires to the tested voltage to measure voltage and frequency without power supply.. It is for testing AC 80V to 300V with high accuracy and high working efficiency of 2 timess measuring speed.. Only suitable for AC45-65Hz mains supply,This voltmeter is designed using the principle of capacitor step-down. Because the higher the frequency, the smaller the impedance of the capacitor, so it is not suitable for high-frequency electronic speed regulation, unconventional AC sine wave frequencies, or other high-frequency equipment. Otherwise, it may appear inaccurate test or damaged voltmeter.. Two wires direct connection, standard installation size, can work under extreme environmental condition..

Measures All EmfsOlmlmo Emf Meter measures magnetic, electric, and radio frequency radiation, when some other meters did not. If you care about EMF radiation in your home, you need to be able to measure all types of radiation.EMF Meter equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on an LCD screen after processing by the micro-control chip.
