Product Details
KGD - WQ - 525 Special Calibrator for Zero Gas Generator
Product Introduction
The KGD - WQ - 525 Special Calibrator for Zero Gas Generator is a
gas - analysis calibration device developed based on self - owned
core gas - analysis technology. It is specifically designed for the
calibration and detection of zero gas generators. This product is
characterized by high measurement accuracy, long service life, and
good stability. It can accurately measure and determine whether the
concentrations of gas components such as NO, NO₂, C₃H₈, CO, CO₂,
and O₂ in the zero gas purified by the zero gas generator meet the
requirements for zero gas in GB 18285 - 2018 and GB 3847 - 2018.
Product Features
- Can simultaneously measure and calibrate gas components such as NO,
NO₂, C₃H₈, CO, CO₂, and O₂.
- With constant - temperature control, it is less affected by the
environment.
- Uses imported light sources, ensuring stable performance.
- By optimizing absorption peaks and using interference -
compensation algorithms, cross - interference is minimized.
- Short pre - heating time and fast response speed.
- With a modular design, it is easy to integrate and has a low
maintenance cost.
- Portable in appearance and easy to operate. The user - friendly
design of "push - and - measure" makes it suitable for working
conditions where frequent movement among multiple detection lines
is required.
