The system features a standardized and modular design with high precision and strong stability. It utilizes advanced optical sensor technology, internet technology, wireless communication technology, and computer networking technology to provide a comprehensive real-time monitoring system for the emissions of odor gases and other pollutants. The system employs the ultraviolet differential method to directly monitor the following factors: Ammonia (NH3), Hydrogen Sulfide (H2S), Trimethylamine (C3H9N), Methyl Mercaptan (CH4S), Dimethyl Sulfide (C2SH6), Dimethyl Disulfide (C2H6S2), Styrene (C8H8), Carbon Disulfide (CS2), temperature, humidity, atmospheric pressure, and more. Optional features include: Odor Unit (OU) (electrochemical), Total Volatile Organic Compounds (TVOC) (PID), wind speed, wind direction, etc. Each factor can be freely selected and combined, and it supports data upload to a cloud platform

Main Features

● The device employs the principle of Ultraviolet Differential Optical Absorption Spectroscopy (DOAS). 

● High-performance ultraviolet spectrometer with a long service life; its special structural design effectively minimizes the impact of vibrations. 

● By analyzing continuous spectra, it can simultaneously measure the concentrations of multiple gaseous chemical components, offering high integration and cost-effectiveness.

● Utilizes the DOAS (Differential Optical Absorption Spectroscopy) algorithm and performs multi-stage preprocessing of the sampled gas, ensuring that measurement results are not affected by factors such as smoke and moisture, resulting in high measurement accuracy. Additionally, the module employs a self-tuning PID algorithm for high-precision temperature control and heating, allowing core components to operate at a constant temperature and avoiding data variations caused by temperature changes (temperature compensation), making it suitable for complex working conditions

● Adopts a dedicated algorithm to eliminate cross-interference between gases. 

● Utilizes a pulsed xenon lamp as the light source with a lifespan of up to 109 pulses; features a solid-state spectrometer with no moving parts. 

● The optical path of the gas chamber is reflected multiple times; with a 6-meter long gas path and a compact volume, it ensures high measurement accuracy.

● The internal core components are designed with a modular approach, allowing for direct connection between the spectrometer and the gas chamber, facilitating easy maintenance.

● Equipped with multiple high-performance processors, the communication between processors utilizes high-speed data bus technology. Each module features robust digital configuration and detection capabilities, supported by a user-friendly touchscreen interface for simple and convenient operation

● Capable of multiple working modes including online monitoring, mobile monitoring, and emergency response, with monitoring data uploaded to a data platform for the supervision, tracking, and tracing of greenhouse gases.

● The sealed independent gas chamber UV module allows for calibration using standard gases.

● The sampling pipelines are made of anti-corrosion and anti-adsorption materials to ensure sample integrity, featuring a safe design that enables unattended operation.

● An integrated data acquisition and transmission unit that is compatible with the "Online Automatic Monitoring Integrated data collection and transmission

● Built-in UPS power supply system ensures information upload during power outages.

● The circuitry utilizes an industrial-grade embedded processor suitable for harsh outdoor environments, with an operating temperature range of -30 to 70 °C.

● It not only enables remote data transmission but also allows for remote monitoring of the instrument's operational status and diagnostics of equipment faults. 

● The terminal device can remotely upgrade its applications via an FTP server, enabling remote maintenance to ensure users have access to the latest applications and timely updates of system functionalities.

● It features a built-in massive data storage unit capable of recording over three years of testing data and instrument operation logs.

● Utilizing an industrial-grade data transmission module, the data transmission is stable and reliable, with various communication methods available for customer selection, including 3G/4G/5G, RS485, ● RS232, and more, supporting concurrent transmission to up to eight cloud platforms.

● The sampling of gaseous pollutants employs dynamic PID flow control with a long-life sampling power system, which is quiet and efficient；

● Real-time field data is displayed on the terminal instrument, refreshing every 5 seconds.

● Optional IP cameras with various parameters can ensure night-time and long-distance shooting requirements, capable of automatic snapshots and real-time viewing by users.

● An optional data service platform can display minute, hourly, and daily averages, with reporting and analysis features that generate daily, monthly, and yearly reports as well as trend analyses. It supports multi-point display on the same screen and data queries via mobile terminals, as well as data pushing to display terminals.

The installation methods are diverse and can be selected based on on-site conditions, including bracket mounting, pole mounting, and more. All installation methods are robust and reliable, capable of withstanding sudden gusts of wind up to level 12.
