Product Details
Trace Oxygen Analyzer KGD-GAS-213
Product Introduction
The Trace Oxygen Analyzer KGD-GAS-213 is based on the limiting
current type zirconia oxygen sensor technology, which enables the
measurement of oxygen concentration at the ppm level in industrial
processes. It has the characteristics of high measurement accuracy,
fast response time, and good stability, and 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,
is small in size, and is easy to install under complex working
conditions. At the same time, it is equipped with an intuitive and
rich user interface, providing an excellent human-machine
interaction experience.
Product Features
- High measurement accuracy, capable of ppm-level measurement
- Fast response speed, providing measurement results within seconds
- Good product stability, no need for regular calibration
- Compact modular design, small in size and convenient for
installation
- Strong human-machine interaction, with rich and intuitive display
content and easy operation
