High-accuracy infrared frequency tester that measures and displays remote-control frequencies while checking IR sensor sensitivity. Built for technicians, installers, and anyone who needs reliable remote-control diagnostics and configuration. Key benefits Accurate frequency readings: Precisely measures the operating frequency of wireless infrared remotes so you can confirm correct signal output and troubleshoot misaligned or failing units. Confirms IR sensor performance: Tests infrared sensing/sensitivity to help identify weak or damaged sensors in remotes and receiving devices. Simplifies remote configuration: Allows manual frequency adjustment when programming or matching replacement remotes, reducing trial-and-error and setup time. Built to last: Drop-proof, wear-resistant construction stands up to frequent use in workshops, service vans, and field environments. Main features Clear, easy-to-read display for immediate test results. Infrared sensing test mode to evaluate sensor responsiveness in addition to frequency measurement. Frequency adjustment controls for precise tuning when configuring remotes. Durable housing that resists wear and accidental drops for long-term reliable performance. Compatibility and performance Designed for use with standard infrared wireless remote controls and infrared sensors across consumer electronics and equipment. High accuracy frequency testing ensures dependable results for diagnostics and configuration tasks. Portable, user-friendly interface for fast on-site use by technicians and hobbyists. Typical applications Service and repair: Diagnose failing TV, set-top box, air conditioner, or AV component remotes by verifying emitted frequency and sensor sensitivity. Installation and programming: Match or tune replacement remotes and program universal remotes with accurate frequency adjustment. Quality checks: Test batches of remotes or receivers in manufacturing, warehousing, or field service to ensure consistent IR performance. What you get A precise infrared frequency tester that combines frequency measurement, IR sensor testing, and convenient frequency adjustment in a durable, user-friendly package.
