GNL-B1A Portable Trace Oxygen Analyzer
-
With overpressure protection, when the pressure in the gas path exceeds the pressure protection range, automatically cut off the gas path on both sides of the sensor chamber;
-
High precision temperature and pressure automatic compensation, reduce the impact of temperature and pressure on the measurement accuracy;
-
Unique solenoid valve protection gas path: built-in solenoid valve protection gas path, the protection valve can reopen unlimited times and have a long service life;
-
Microcontroller controls the analyzer to be in bypass or sample mode.
