The VELLEMAN MK137 Infrared Remote Control Checker Kit is a compact electronic tester designed to quickly verify the operation of infrared (IR) remote controls. Ideal for technicians, electronics enthusiasts, installers, repair workshops, and home users, this easy-to-build kit provides a fast and reliable way to determine whether an infrared remote is transmitting a signal.
Using the MK137 is simple. Point any compatible infrared remote control at the built-in IR sensor and press any button. If the remote is functioning correctly, the unit immediately responds by illuminating four flashing LEDs, providing a clear visual confirmation that the infrared transmitter is operating.
The tester is invaluable when troubleshooting televisions, satellite receivers, media players, air conditioners, home theatre equipment, DVD players, audio systems, and other appliances that use infrared remote controls. It quickly helps determine whether a fault lies with the remote control itself or with the receiving equipment, saving time during diagnosis and repairs.
Designed with low power consumption of only 15mA, the MK137 operates efficiently from a standard 9V battery (not included), making it completely portable for use in workshops, service calls, retail counters, classrooms, or home electronics maintenance.
Its compact size allows the completed tester to fit easily into a toolbox or technician's equipment bag, ensuring it's always available whenever remote controls need to be checked.
Supplied as a self-assembly electronics kit, the MK137 is also an excellent educational project that introduces users to infrared detection technology, optical sensors, LED indication circuits, and electronic testing equipment. The straightforward design makes it suitable for beginners while producing a practical diagnostic tool for everyday use.
Whether servicing consumer electronics, diagnosing faulty remote controls, assisting customers in retail environments, or learning about infrared communication, the VELLEMAN MK137 Infrared Remote Control Checker Kit provides a quick, reliable, and convenient method of testing IR transmitters.
