No need for reduced pressure with a vacuum chamber! High-sensitivity measurement of hydrogen using a semiconductor gas sensor.
The "PDHA-4000" is a device for analyzing hydrogen in solid metallic materials such as iron. The sample is heated from -100°C using a thermal desorption device (SDS-P3), and the resulting trace hydrogen is measured with high sensitivity using an SGC (SGHA-P3-A1). Analysis can be performed under atmospheric pressure, and measurements can be taken using argon, nitrogen, or compressed air. It also features automatic measurement and calculation result graph display and data storage functions via PC. 【Features】 ■ High-sensitivity hydrogen measurement using a semiconductor gas sensor (10 to 10,000 vol.ppb) ■ Measurement time as short as 2 minutes per measurement ■ Heating range from -100 to 800°C, with heating rates adjustable from 1 to 1200°C/hour ■ Conversion program for hydrogen release amount to mass ppm ■ Safety device included with a dedicated rack *For more details, please refer to the PDF materials or feel free to contact us.
