Product Description:
Characteristics 1.There are two LEDs which can turn 360o and watch the situation of the detector at any angle. 2.The use of common base is advantageous to the exchange of detector.
Product Description:
The UV TRON is a bipolar tube with a structure similar to that of a phototube. the inside of the UV TRON tube is filled with a special gas. It is only sensitive to ultraviolet rays. When UV glass due to the photoelectric emission effect. Then a large current is rapidly generated between the anode and the cathode and electricity is discharged. The strength of UV rays which pass through the UV glass is monitored by electronic circuitry which triggers the detector unto the alarm state.
Product Description:
