Instructions
ㆍ Sensor principle:please refer to page 2 of this sample book;
ㆍ Application and Ordering Notes:Please refer to page 16 of this sample.
-Overvoltage protection function:when the pressure of sample gas exceeds the protection range,the gas path will be cut off automatically to avoid damage of sensor due to too high or too small pressure;
-Advanced compensation function:The analyzer has the functions of pressure compensation and digital temperature compensation to eliminate the influence of pressure and temperature on oxygen concentration measurement.
-Overrange protection function:When the oxygen concentration is higher than the protection concentration, the gas path will be cut off automatically,so as to avoid the sensor’s life being affected by the environment with high oxygen concentration for a long time.
-The unique solenoid valve can protect the gas path:the built-in solenoid valve protects the gas path,and has unlimited opening times and long service life.The microprocessor controls the purge or test status of the gas path.
-Personalized test chamber:Fuel cell oxygen sensor itselfdetermines that it must be replaced after reaching its service life.The test chamber used in this analysis is a new structure design,which can not only meet the needs of sensor replacement without any tools on site,but also need not use standard gas calibration.
-Menu lock switch:to prevent misoperation to change the parameters of the analyzer,affecting its normal operation;
-Self-set analog output:isolated analog signal output, 4-20mA/0-20mA/0-1V/0-5V/0-10V/1-5V analog output mode an be set freely through the menu. GNL-B1A portable trace oxygen analyzer
