Product Description

 Hk-809 magnetic field / electromagnetic wave detector is not only a high-sensitivity electromagnetic wave detector, but also an advanced magnetic field detector. Its original digital linear magnetic field detection technology can effectively detect weak magnetic field signals. Compared with the reed detection technology used in ordinary magnetic field detector, the performance of the reed detection technology is greatly improved, which is very beneficial for the search of wireless strong magnetic GPS positioner.

Magnetic field detection distance up to 200 mm

Electromagnetic wave detection distance up to 5m

Hk-809 adopts the magnetic field / electromagnetic wave dual channel simultaneous detection technology, which does not need to switch back and forth in the magnetic field / electromagnetic wave like the ordinary multi Lake Wood Road detector. A common detector needs to detect twice, and hk-809 only needs to detect once, which effectively improves the efficiency of detecting automobile positioner.
