Beebird NH3 Analyzer Module

    HealthyPhoton introduced BeebirdTM -- a next-generation QCL based, cost-effective OEM solution for ultra-sensitive NH3 online monitoring. Combined with the customer’s sampling and dust removal pretreatment system, BeebirdTM requires only high-temperature heat tracing throughout the entire process without condensation, dewatering,  or sample dilution. It is very suitable for installation near the sampling points. With BeebirdTM's good real-time performance and small maintenance, it is possible to provide the real-time feedback and optimization for the next-generation combustion and denitration processes.
