Portable Trace Oxygen Analyzer (CI-PC931/932)
-
High precision temperature and pressure automatic compensation, reduce the impact of temperature and pressure on the measurement accuracy;
-
With overpressure protection, when the pressure in the gaspath exceeds the pressure protection range, automatically cut off the gas path on both sides of the sensor chamber;
-
The use of digital sensors, convenient for users to replace on site, device is ready to be used once the sensor is replaced.
