Wise Co., Ltd.has been pursuing technological innovation and the highest quality in the field of pressure, temperature, gas, flow and level measurement for more than 50 years. It is equipped with the latest production and measurement facilities and provides customer service through more than 60 domestic and overseas agencies. Our products are used for pressure, temperature, gas, flow and level measurement, analysis and control in all industrial processes such as renewable energy, semiconductor, food and beverage, biotechnology, pharmaceutical and steel, ship building, power generation, oil, gas and petrochemical industries. We supply pressure gauges for semiconductor industries.
As a part of semiconductor process, the gas panel controls the flow of gas into the process chamber. Pressure transducers are installed inside of the gas panel on each of the gas sticks to monitor the pressure output of the pressure regulator. This position enables them to send signals that adjust system operation with greater precision, accuracy, and speed, resulting in better overall system function.
