Overview
KSA-7000 is a flue gas analyzer based on tunable diode laser absorption spectroscopy (TDLAS), measuring various gas components including CO, CO2, H2S, NH3, O2, HCl and HF.
It uses a hot & wet sampling method through a sampling line heated to 120~190℃, analyzing exhaust gas directly without a chiller and minimizing condensation and loss of gas components.
It provides 4~20 mA analog output for each gas and is used for coal gasification and pyrolysis, waste incinerators, cement plants and industrial stack emission measurement.
