CLD NOx analyzer

Next generation solid-state chemiluminescence NOx analyzer 

*Product currently available in United States (US) only

CL3020 CLD NOx analyzer utilizes next generation solid state detection technology to measure low and ultra-low NOx in combustion applications.
CL3020 is especially designed for measurements in gas-fired power plants covered under 40 CFR Part 75 and various installations such as incinerators, pulp and paper plants, steel & iron plants, cement plants, oil-, gas- and chemical plants covered under 40 CFR Part 60, 61, 63 and 65.
The CLD NOx analyzer CL3020 supplements ABB's extensive CEMS offering, including the EL3000 and AO2000 series and market leading NDIR, NDUV, paramagnetic O2 and FID sensors installed more than 60,000 times worldwide.



CL3020 is so compact that two NOx cells may be mounted inside a single housing allowing continuous NOx speciation or NH3 measurement.
The simplicity of the design also leads to much greater reliability. No more high voltage power supplies, exposed thermo-electric cooling or fragile optical components means fewer things that can go wrong.
