DIGITAL DETECTOR AND RADIO FREQUENCY METER RAKŠI-120

Exceptional in that pocket-sized radio frequencies meters SEL SP-71R Rakši uses advanced microprocessor technology to measure and analyze electromagnetic fields in 50MHz - 3.3 GHz . It was designed to detect and locate all types of devices such as radio broadcasting

Mobile phones operate on GSM900/1800 and UMTS (3G) networks, CDMA450

Phone standard DECT

Bluetooth and Wi-Fi devices

Wireless cameras

Analog transmitters (AM, FM, PM)

Radio transmitters with digital modulation (FSK, PSK, etc.)

Sensors with broadband modulation and bandwidth up to 10MHz

The device can operate in two modes: alarm mode allows you to verify that there are any new transmissions near the detector, and the sensing mode detects some radio transmissions and measurement frequency. 

Small size and the ability to set alarms invine vibration gives the user the ability to detect discrete information about potential surveillance threats.
