HT-LA431 Trace Oxygen Analyzer is applied in the online oxygen analysis industries such as petrochemical industry, air separation, semiconductor industry protective gas detection, food production process gas detection, oxygen concentration measurement in hydrocarbon, etc.
a. Menu can be switched between Chinese and English and the operation is intuitive and convenient;
b. 320×240 graphic dot-matrix color LCD display is clear to see;
c. Original imported fuel cell sensor has rapid response speed, high measurement accuracy, long calibration cycle and strong anti-interference capacity, etc.;
d. Unique protection gas circuit could protect the sensor effectively, preventing damaging sensor’s service life because of exposing the sensor in air for too long;
e. Automatic temperature compensation function could reduce the impact of environmental temperature changes on the measurement accuracy;
f. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
g. 40 thousand pieces of historical data can be stored locally automatically and can be read at any time;
h. 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.
