  • Product Description

Product Introduction:

BLA-820 flue gas analyzer (infrared) is a gas analysis product independently developed by the company for domestic and international environmental online monitoring and industrial online analysis working conditions. This analyzer is based on non dispersive infrared technology (NDIR) and chemometric algorithm (PLS), and can measure gas concentrations such as O2, CO, CO2, CHC4, C3H8, SFC6, N2O, etc. It has the characteristics of high measurement accuracy, strong reliability, low operating cost, fast response time, large range span, and wide application range. All indicators reach or exceed similar products at home and abroad.

Product features:

Adopting the most advanced infrared wavelength filtering technology (GFC) and long path gas absorption cell technology (L-Cell)

Can detect ultra-low range gas concentration.

Low temperature cooling type infrared detector, low drift, high precision, low power consumption, fast response.

High performance infrared light source, long service life, and special structural design effectively avoid the influence of vibration.

Customize ultra narrow band filters for target gas absorption bands to minimize cross interference in multi-component gas measurements.

Modular design: The light source, sensor, core circuit, gas chamber, etc. adopt modular design, which has high reliability, good scalability, and easy maintenance.

Product application:

Greenhouse gas monitoring of fixed source emission outlets such as coal-fired power plants, waste to energy plants, cement plants, glass plants, lime plants, ceramic plants, sintering, coke ovens, desulfurization processes, denitrification processes, etc.
