Features:
Premium Material: The housing is made of solid plastics material, fallproof, wear resistant, and with nice durability.
Digital Display: 4-bit digital display of radiofrequency micro-computer measuring instruments, you can see the tested frequency clearly.
LED Light Design: The instrument is equipped with LED illumination, which is more convenient for using in the dim light environment.
Indicator Light: Equipped with an infrared input indicator, the red light shows that the infrared output of the remotes control is normally emitted; If the indicator is off, means the infrared emitter failure, damage or other reasons.
9V Battery Power Supplys: Built-in a 9V battery, large capacity and can provide long service time.
Wide Applications: It can be used to test the frequency of the remotely control and display it clearly; it can also test the goodness of infrared sensing; it allows you to easily adjust the frequency you need when formulating the remotes control.
