Detailed Product Description

The Description of Instrument

LVPR300 series are large-capacity recording instruments adopt single chip microprocessor as core, monochrome or color LCD with big screen, with functions as f with temperature and pressure compensationess, the PID adjustment and so on. This series also have advantages such as intelligence adjustment, smart bus, electronic storage, omnipotent input, adaption to complexity of spot signal, online self-correction, self diagnosis and 0.2% FS accuracy. And also have advantages as high performance, high reliability,small; maintenance, without expendable etc. Considered as the replacement for normal paper recording instrument,LVPR200 series have been widely used in chemical, electric power, steel, light industry, construction materials, environmental protection, bio-chemical, pharmacy, food and package etc. industries

Note

If the needs temperature and pressure compensationess, input channels for temperature and pressure compensationess each are needed.
