Portable Trace Oxygen Analyzer (CI-PC93)
-
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 pressure automatic compensation, reduce the impact of pressure on the measurement accuracy;
-
With over range protection, when the oxygen concentration is higher than the protection limit value, the device will automatically cut off the gas path on both sides of the sensor chamber, to avoid the sensor in the high oxygen concentration environment for a long time and affect its performance and life.
