Car Key Infrared Frequency Tester 100M-1GHz, Digital Infrared Meter

Main Description

The Digital IR Frequency Tester CNBJ-501 is your go-to tool for precise infrared frequency measurement and remote-control troubleshooting. Designed to test the carrier frequency of wireless remotes—from car keys and door keys to air conditioning and TV remotes—this compact device displays measurements clearly on a 4‑bit digital readout. With a test range of 100 MHz to 1 GHz, you can quickly verify, fine‑tune, and align the exact frequency your remote system requires, helping you avoid misfired commands and frustrated users.

Housed in a durable black plastic body, the tester runs on a 9V battery (included), and it supports a broad voltage range (6–24V DC) for flexible use in workshops or on the go. Whether you’re a hobbyist, a locksmith, or a technician configuring custom remotes, this instrument makes IR testing straightforward and reliable. Easy to operate, it highlights frequency readings so you can adjust or program remotes with confidence.
