HH-5200 Ammonia Online Monitoring System

Product Introduction

The HH-5200 ammonia online monitoring system (NH3, NO, O2) is based on the principles of tunable semiconductor laser absorption spectroscopy (TDLAS) and ultraviolet differential absorption spectroscopy (DOAS) technology. The system consists of three main parts: preprocessing, gas analysis module, and data processing and display. The tested gas undergoes high-temperature sampling probe dust removal and dehumidification, high-temperature transmission through heat tracing tubes, and enters the high-temperature gas analyzer module (TDLAS+DOAS) for analysis and measurement. Effectively solved technical problems such as blockage of flow paths caused by low-temperature crystallization of ammonium salts, measurement accuracy deviation caused by the precipitation and dissolution of NH3 in condensed water, and seamless measurement caused by high dust attenuation in in-situ systems.

Performance characteristics

1. Avoid background gas interference, low detection limit, and small range drift;

2. Heat tracing above 180 degrees to avoid ammonium salt crystallization and water absorption;

3. The structure is lightweight, easy to install, and has low maintenance costs;

4. Multi parameter integration, measuring multiple components.
