This product is developed based on semiconductor laser absorption spectrosc- opy (DLAS) technology, with integrated design and high degree of integration. The system adopts the in-situ measurement mode which does not need sampling prep- rocessing. It can quickly, accurately and reliably measure various kinds of process g- ases such as industrial process gases and flue gas emissions, provide the best solut- ion for online gas monitoring.
Feature
☆ Integrated design with high reliability.
☆ With multiple technologies, such as semi-
conductor absorption spectrum, digital signal
processing, integrated positive pressure explosion-
proof control, leads to compact design and high reliability for the system. Mean-
while, for explosion-proof applications, with an embedded positive pressure con-
trol module, the system can perform real-time monitoring with explosion-proof
purging positive pressure to meet the requirements of various applications.
☆ The emitting unit integrates an LCD display screen and a keyboard, by which
users can directly carry out calibration and parameter setting on the installation
site. Meanwhile, the system also supports Bluetooth communication. Users can
communicate wirelessly with the analysis system through the WT-200 mobile APP,
convenient and fast.
