About Us
Leader has earned a worldwide reputation for designing and manufacturing some of the most reliable, practical and cost effective electronic instruments available. The products were originally developed for production testing and servicing. These are applications in which ease-of-use and highest reliability are essential. By expanding into a broad line of industrial and video instruments, Leader was able to add to these fundamental qualities a cost-performance ratio unequalled in the industry.
Manufacturing quality is built in every step of the way. Only the finest parts are used for optimum reliability. At each production run, sub-assemblies are separately tested before they are integrated into the finished product. Then product is tested. Less than 1% of all Leader products made are ever returned for warranty repair or adjustment.
