Sapphire Instruments is a privately owned Taiwanese corporation. It was founded in 1988 with the vision to provide test-instruments of high quality and high performance. Our sole shareholder and general manager, Mr. Jeff Hsu, a former university assistant professor, developed the world’s first handheld active differential probe. Sapphire Instruments has developed a series of professional quality active differential probes. We are now established as a world-class manufacturer in the field of differential probes and our distributor network means that engineers worldwide have access to our products. As our business developed we established a subsidiary company Sapphire Instrument Subic Bay, Inc. in 2006 in the Philippines. We have now transferred production to Subic Bay. Research & Development still remains in Taipei. Sapphire Instruments Subic Bay, Inc. follows our corporate quality policy in order to achieve our first and foremost objective, customer satisfaction. At Sapphire Instruments Subic Bay, Inc. we produce our series of high voltage and high frequency differential probes. As a professional manufacturer of active differential probes, Sapphire Instruments provides a complete solution for a wide range of measurements. All of our products can directly draw power from oscilloscopes or use batteries and/or a mains adaptor. They are divided into two categories: first, differential probes for high voltage power measurement. In this category, we provide models with input voltages of up to 7,000 Volts and with bandwidth up to 100MHz. Our second category is differential probes for high speed signal measurement. In this category we provide models with an input voltage range of up to +/-15 Volts and with bandwidth up to 800MHz. In the future, we plan to develop a new high voltage active differential probe with an input voltage up to 40,000 Volts and with bandwidth up to 50MHz. We are also going to develop a new high speed active differential probe with input voltage up to +/-150 Volts and with bandwidth up to 1GHz.
