Hong Kong Sensor Technologies, Inc. (HKST) is a manufacturer of MEMS pressure sensors, pressure transducers, and pressure transmitters. HKST is a subsidiary of American Sensor Technologies, Inc. (AST), a New Jersy, USA Corporation. HKST is authorized to manufacture and sell the full line of AST Pressure Sensor product in the ASIA region.

Using Krystal Bond Technology, AST/HKST is the leader in pressure sensing solutions. Without the use of welds, fluid filled cavities or O-rings, AST/HKST pressure sensors are machined from a single piece of stainless steel. These pressure sensors are built with a thick diaphragm and state-of-the-art strain gages to provide excellent accuracy, high proof pressure, long-term stability, and high electrical isolation.

AST/HKST's one-piece sensing element design is available in 316L stainless steel for applications including, but not limited to, hydrogen measurement, explosion-proof areas requiring NACE and Single Seal approval,
as well as NSF61 water pressure applications.
