Industry Information
Temperature measurement operation in high temperature and high pressure place of high temperature and high pressure thermocouple
2012-2-27 13:11:02

适合于石油、化工等生产过程中的高温高压场所的温度测量与控制。 High temperature and high pressure thermocouples are suitable for temperature measurement and control in high temperature and high pressure places in the production process of petroleum and chemical industries. It is an indispensable temperature device for oil refineries and high-pressure polyethylene.
