HT-LA433 Oxygen Analyzer is widely used in online measurement and analysis of oxygen concentration in nitrogen production by air separation, smelting industry, medical and health industry, petrochemical, electronic power and other industries, etc.
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. It could operate in air for a long time without shortening sensor’s service life;
e. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
f. The response speed is rapid and it could measure 0.1 PPm at minimum;
g. Automatic temperature and pressure compensation could reduce the impact of environment temperature and pressure changes on the measured accuracy;
h. 40 thousand pieces of historical data can be stored locally automatically and can be read at any time;
i. 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.
