Online Trace Oxygen Analyzer (CI-PC91)
Online Trace Oxygen Analyzer (CI-PC91)
-
Overpressure protection: when gas path pressure exceeds the protection range, the system automatically cuts off the gas path on both sides of the sensor chamber.
-
High-precision automatic temperature and pressure compensation, reducing the impact of environmental changes on measurement accuracy.
-
Over-range protection: when oxygen concentration exceeds the protection limit, the system automatically shuts off the gas path on both sides of the sensor chamber, preventing prolonged exposure to high oxygen levels and preserving sensor performance and service life.
