Product Description

(Ammonia) In-situ Through-type Laser Gas Analyzer It is an industrial-grade online analytical instrument based on the core technology of Tunable Diode Laser Absorption Spectroscopy (TDLAS), specially developed for the high corrosivity and strong toxicity of ammonia as well as the real-time monitoring needs of industrial processes. With the core design concept of "in-situ accurate monitoring, corrosion-resistant stable operation and real-time data output", the product innovatively adopts a through-type installation structure, which breaks through the pain points of traditional gas analyzers such as sampling lag, weak anti-interference performance and frequent maintenance, providing a continuous and reliable online monitoring solution for ammonia concentration in chemical, environmental protection, chemical fertilizer and other fields.

Relying on the "fingerprint-level" identification technology of TDLAS laser, the analyzer is accurately calibrated for the characteristic absorption spectral lines of ammonia, featuring extremely strong detection specificity. It can effectively avoid environmental interferences such as water vapor, dust and other gases, achieving accurate measurement of ammonia concentration at ppm level, with its data real-time performance and reliability leading the industry. In-situ monitoring ensures zero lag: the laser directly penetrates the measurement area to capture the dynamic changes of ammonia concentration in real time without sampling and transmission delays, providing accurate data support for the closed-loop control of industrial processes. The installation is convenient and flexible for expansion, supporting the installation on multi-diameter pipelines and square flues without the need to modify the process flow. It realizes full-process intelligent management and control, supporting 24/7 uninterrupted operation, with real-time display of concentration data, historical curve tracing and over-limit alarm functions. It also allows remote parameter configuration and fault diagnosis, achieving integrated management of "monitoring-control-operation and maintenance".
