Masterclock is Quality
Masterclock synchronization devices are designed and manufactured exclusively in the United States, allowing complete control of manufacturing and design quality.
All Masterclock devices are designed in a robust metal case. A commercial-grade metal housing improves shock and vibration performance while preventing electromagnetic interference. This keeps nearby devices from interfering with clock performance as well preventing the electrical signals within the clock from compromising the performance of other electrical products.
Masterclock analog clocks only use metal movements. After extensive testing, the life of plastic movements is on average two years, which is unacceptable for a commercial grade product.
Our digital clocks use Light Emitting Diodes (LED). LEDs offer a life that is hundreds of times greater than LCDs and have larger viewing angles, wider temperature ranges, better shock and vibration performance, improved sunlight readability and do not require back-lighting.
Commercial-grade components are specified and tested extensively. While more expensive, a product made with commercial-grade parts provides a more reliable product with a longer service life. Masterclock has committed to this philosophy of quality since 1994.
