Overview
KSA-7100UV is a gas analyzer based on tunable diode laser absorption spectroscopy (TDLAS) that measures NH3 and HCl concentrations.
Highly selective measurement reduces background-gas cross interference, and it is little affected by temperature and pressure changes. It features in-situ extractive sampling, a response time (T90) within 30 seconds and IP65 protection.
It is used for NH3 and HCl measurement in coal gasification and pyrolysis, cement plants, waste incinerators and pollution control facilities.
