-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 itself
determines 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
can be set freely through the menu.
