KGD - MQ - 538 Trace Oxygen Analyzer Product Introduction The KGD - MQ - 538 Trace Oxygen Analyzer is based on limiting
current - type zirconia sensor technology. It enables the
measurement of oxygen concentration at the ppm level in industrial
processes, featuring high measurement accuracy, fast response
speed, and good stability. It can be applied in fields such as
semiconductor manufacturing, air separation, and inert gas welding,
providing reliable performance for key process control
applications. The product adopts a compact modular design, which is
small in size and easy to install in complex working conditions. It
is also equipped with an intuitive and rich user interface,
offering an excellent human - machine interaction experience. Product Features - High measurement accuracy, capable of ppm - level measurement.
- Fast response speed, providing results in seconds.
- Good product stability, no need for regular calibration.
- Compact modular design, small size, and easy installation.
- Strong human - machine interaction, with rich and intuitive display
content and convenient operation.
- Strong anti - interference ability, low cross - sensitivity to
other gases.
- Alarm function: An alarm will be issued when the oxygen
concentration deviates from the alarm value, and the alarm value is
adjustable.
