Features:
   a.   Friendly communication menu allows an intuitive and convenient operation;
   b.   320×240 graphic dot-matrix color LCD display is clear to see;
   c.   The original imported zirconia sensor consumes no service life when the power is off, and has a high measurement accuracy, rapid response speed and small zero drift value, etc.;
   d.   With the gas circuit blockage alarm and self-protection function, the instrument could turn off the sampling pump automatically when the gas circuit malfunctions, which could extend the service life of sampling pump and sensor;
   e.   The oxygen concentration in the protection gas furnace can be controlled automatically, and it could respond quickly without human intervention;
   f.    The control error caused by gas source pressure and temperature change can be compensated automatically, stabilizing the gas composition in the system;
   g.   With the PID parameters self-adjustment function, the instrument could calculate the optimal PID control parameter according to the relation between control output and oxygen concentration sampling input when user performs self-adjustment operation, realizing the accurate and automatic control of oxygen concentration. The whole operation process is easy and convenient;
   h.   The instrument could save protection gas to the maximum, cutting down the maintenance cost of the system effectively; 
   i.    With the bypass protection function, the bypass solenoid valve could be opened in time automatically when error occurs in the proportion valve, and pump protection gas into the protection gas furnace. The response is rapid without human intervention, and could reduce the loss resulted by proportion valve error (optional);  
   j.    Original imported sampling pump is built in and has a long service life and stable performance;
   k.   Power is supplied by alternating current in a wide range and it is more applicable;
   l.    No calibration gas is needed and the instrument is not affected by the oxygen content in the operation environment;
   m. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
   n.   RS232 (default) or RS485 digital communication port can be selected according to clients' requirement, to realize unidirectional or bidirectional communication with computer or other digital communication facilities.
   o.   Upper computer software can be equipped. The software's function includes display in curve, data storage, analyzer parameters setting, etc.

Application:
   It is widely used in the measurement and control of oxygen concentration in air separation, protection gas of wave soldering/reflow soldering, protection gas furnace, gas production and manufacturing, petrochemical and other industries.
