KGD - SF - 501 Online Monitoring System
Product Introduction
The KGD - SF - 501 Online Monitoring System is a high - performance
gas analysis instrument. Based on the principles of Ultraviolet
Differential Optical Absorption Spectroscopy (UV - DOAS) and Non -
Dispersive Infrared (NDIR) measurement technology, it adopts a
reliable and stable light source, high - performance detector, and
precise signal processing circuit. It features high measurement
accuracy, strong anti - interference ability, and stable
performance during long - term use. It is especially suitable for
measuring low - concentration SO2, H2S, and CO components in the
gas decomposition products of KGD - SF - 501.
The system consists of a light source, a gas cell, and a detector.
Using UV - DOAS and NDIR technologies, it determines the
concentration of the measured gas by measuring the light intensity
entering the sensor. The ultraviolet measurement part uses an
imported xenon lamp light source and a high - resolution
spectrometer. The software applies the UV - DOAS algorithm.
Combined with a long - optical - path folded - back gas cell, it
can accurately measure H2S and SO2 gases in KGD - SF - 501 gas
without being interfered by background gases.
The product adopts a modular design for easy installation. It is
equipped with a dew - point measurement unit that can provide real
- time feedback on the trend of equipment signal changes.
Operations such as calibration and standardization can be carried
out through RS - 232/RS - 485 communication interfaces, which is
convenient for customers to integrate and maintain.
Product Features
- Adopts UV - DOAS and NDIR technologies, ensuring high measurement
accuracy.
- Fast response speed and strong anti - interference ability.
- Constant temperature control reduces the impact of ambient
temperature, with strong stability.
- Modular design for easy integration.
