This is an electromagnetic wave meter kit that uses two antennas on the board and an inductor antenna to receive and detect electromagnetic waves of high frequency (cordless phones, radios, microwave ovens, etc.) and low frequency (fan, TV, AC adapter, motor, etc.) and displays the level of DC voltage obtained in 5 levels LEDs.
The SP version is able to adjust the sensitivity of the radio wave received received.
The current consumption is half of the previous model, and the batteries used are 006P type batteries to 2 AA batteries, but the service life is longer.
Main specifications: Power supply voltage: 3 V (2 AA batteries); Operating current: Maximum approx. 12 mA; Standby current: approx. 3.5 mA; Measurement frequency range: approx. 300 MHz - 3 GHz; Low range approx. 300 Hz - 10 kHz display system: 5 levels display board size (W x D x H): 3.7 x 2.2 inches (94 x 57 x 57 cm).
