Selection of high-quality zirconia detection elements has the characteristics of long life and fast response.
• Adopt large-screen dot-matrix liquid crystal display, which can display parameters such as oxygen quantity, temperature, date, time, etc.
• Full Chinese man-machine dialogue menu is adopted, which is intuitive and convenient to operate.
• Adopting convection-diffusion structure, reducing the influence of flow on measuring trace oxygen.
• The instrument has a total of eight ranges from micro to constant, and the range is automatically converted.
• The upper and lower limit alarm points can be set arbitrarily within the full range.
• With paperless recorder function, automatically record the change curve of oxygen concentration with time.
• With automatic storage of measurement data, the storage interval is set by the user.
• With 0~10mA or 4~20mA current signal output.
• The instrument has a standard RS232C communication port, which can be connected to a serial printer or to achieve two-way communication with a computer
