High Performance Temperature Humidity Chamber（GHL-400）

GHL-400+GHS-400

High Performance Temperature Humidity Chamber-GH Series

With the continuous innovation of science and technology, semiconductor technology is also increasingly updated and the demand for reliability testing in the semiconductor industry is increasing. In response to the high heat and high load testing needs of semiconductors and electronic components, Espec (Guangdong) has developed the high performance temperature（humidity)chamber - GH series, which can achieve faster temperature rise and fall rates while maintaining the advantages of the standard GP series, and can correspond to high load and hight heat reliability tests with a maximum allowable heat load of up to 4500W.
