    PKI 4110 Frequency Detector

With the PKI 4110 Frequency Detector, you have a highly sensitive broadband frequency detector at hand providing a very wide frequency range for professional detection and location of radio monitoring systems. Its functionality allows even an amateur to use the basic functions of the device and to achieve protection against eavesdropping. The built-in audio demodulator allows to eavesdrop on analog radio systems. With the Geiger click indicator, the detectionWired Microphone Detector and localization of most of the dangerous eavesdropping systems is simple and efficient. Fitted in a lightweight, compact and rugged metal housing with 4-way signal strength indication (graphical, numerical, delayed and peak), radio transmitters, whether digitally encoded, spread spectrum, hopping or pulse transmissions, no longer escape it. Even mobile phones and computers (including manipulated systems) are perfectly detected. Recording possibilities including time and signal strength complete the equipment.
