Best quality Beijing Topsky - Non-Linear Junction Detector FJT-C-S6 – Topsky

It can search all semiconductor component circuits regardless of their functional status and the target object containing a metal material.
It can effectively search for any type of radio microphone (listening devices), remote control, cable telephone line microphone and loudspeaker hidden electronic detonating devices, and various explosive objects containing metallic shine.
It can effectively guarantee to search on the internal components and defensive structures (floors, ceilings, walls, squares, playgrounds) .Freely telescopic antenna and a wide range of basic parameters of the device regulator ensure that the implementation process to facilitate the search and precise positioning, and can also search for signals received second and third harmonic and metal detection sync signal, the display shows the signal strength and buzzer enhance metal detector synchronization signal.

Technical Data Overview
1．At maximum power and sensitivity mode, the range of the analog detecting is not less than 50cm.Analog Devices select Normal random configuration diode (the transparent body packer).Random adjustable metal detector sensitivity by adjusting the different state environment mode,and therefore will appear on the host instrument metal warning signal, the device through the side of the probe knob to adjust the balance between work, at rest stops 1-3S not appear toot voice prompts.This reaction will make most of the land mine automatically discharged and will not mess alarm in the detection process.Max.distance for metal detector is (5 g metal) 30cm.It is currently the most advanced using digital processing technology and precisely accurate and correct.
2．Built in fixed high-capacity lithium batteries can be rechargeable 1000-1500 times.
3．Power consumption of the device does not exceed 10W
4．Sustainable controlled power play not less than 6 hours and has long standby mode and without a license battery management.
5．The operation buttons (except the power switch) are located on the display which is easy for operation.The display is LCD touch screen with rear-projection light source which can be used to highlight the day in normal light.
6．Standard equipment including package less than 5.2 kg Package
7．Limit temperature range：－20℃～60℃.
8．Relative humidity: when the temperature is 25 ℃, not more than 80%.
