Zirconia Trace Oxygen Analyzer
Features
* New style zirconia oxygen sensor, long life, high precision and fast response
* With man-machine conversation menu, easy to operate.
* Inner special gas-route protects the sensor when it exposures in the air for a long timeby out of power or cutting off the gas-route automatically.
* Setting Upper and lower alarm values freely during the measure ranges.
* 4-20mA signal output
* One standard RS232C or RS485 interface
