UV Flue Gas Analyzer (Ultra - Low Range) KGD - YQ - 514 meets the
market demand for ultra - low emission monitoring.
Product Introduction
The KGD - YQ - 514 UV Flue Gas Analyzer (Ultra - Low Range) is an
online gas analyzer independently developed based on high -
precision ultraviolet differential absorption spectroscopy gas
analysis technology. It adopts a unique algorithm and long -
optical - path multiple - return gas cell technology, endowing the
product with characteristics such as good stability, high
sensitivity, strong absorption signal ability, and long service
life. The product is designed with a standard 4U chassis and can
accurately measure the concentrations of SO₂, NO, and NO₂ gas
components in real - time online, meeting the market demand for
ultra - low emission monitoring.
Product Features
- Excellent performance with linear error ≤ 2% F.S. and response time
T90 ≤ 30s.
- Constant temperature control to reduce the impact of ambient
temperature.
- Optimized absorption peak and interference compensation algorithm
with little cross - interference.
- The light source uses imported xenon lamps, featuring long service
life and high stability.
- Two - way RS232/485 serial port output to meet the requirements of
environmental protection direct data acquisition instruments.
