Sapphire Instruments is a privately owned Taiwanese corporation. It was founded in 1988 with the vision to provide testing instruments of high quality and high performance. Our sole shareholder and general manager, Mr. Jeff Hsu, who was an assistant professor in a university, developed the first handheld active differential probe in the world. Our company has developed a series of active differential probes and established our status as a professional producer in this field. At the moment, we are a worldwide supplier of active differential probes.
As a professional manufacturer of active differential probes, Sapphire Instruments provides a complete set of products.
