1. Full Chinese display, easy to operate: Full Chinese display, beautiful interface: using high-resolution liquid crystal display module, all data, status and operation tips are displayed in Chinese, there is no symbol or code defined by the manufacturer. Simple menu structure, text-based human-table dialogue: Compared with traditional meters,
Characteristic description of the instrument-large-screen dot matrix LCD display, Chinese menu operation, simultaneous display of multiple parameters-menu operation, user-friendly design, simpler use-super anti-interference design can be used for strong interference on-site operations and anti-electromagnetic interference-automatic Conversion of measurement frequency: avoid electrode polarization and improve measurement
Dissolved oxygen electrodes are introduced using polarographic electrodes. The positive electrode is composed of Ag / AgCl and the negative electrode is composed of platinum (Pt). The electrolyte filled with special components is the electrolyte. A silicone rubber permeable membrane is wrapped around the electrode. During the measurement, a polarization voltage of 675 mV is applied between the electrodes, and oxygen penetrates the diaphragm and is consumed at the cathode.
