In the context of increasingly severe global climate change challenges, Duke proudly launches the Portable Soil Water and Greenhouse Gas Monitor. With cutting-edge technology and innovative design, it provides full-scenario solutions for ecological environment research, agricultural monitoring, pollution prevention and control, and other fields, assisting in precise monitoring and scientific decision-making under the "double carbon" goals.

I. Multi-Dimensional Gas Monitoring: Covering Core Indicators and Decoding Ecological Secrets

As a new generation of portable monitoring tool, the EDK 6900-X series can simultaneously measure 10 key gases, including CO₂, CH₄, N₂O, NH₃, SF₆, CO, O₂, and H₂O. It not only covers core greenhouse gases such as soil respiration and water body emissions but also captures polluting gas components like NH₃ and SF₆. With ppb-level detection accuracy (e.g., the minimum detection limit of N₂O is 0.02 ppm, and that of SF₆ is 0.02 ppm) and linear error control within ≤±2% F.S., the device can accurately reveal subtle changes in gas exchange in ecosystems, providing reliable data support for carbon and nitrogen cycle research, pollution source tracing, and other fields.

II. Empowerment by Cutting-Edge Technology: Intelligent Drive and Breaking Environmental Limitations

1. Fusion of Multiple Technologies for Precise Target Gas Locking

• Enhanced TDLAS Laser Technology:      Achieves "fingerprint spectrum"-level detection through      0.1nm-level scanning wavelength, avoiding cross-interference of gas      absorption wavelengths, and is particularly suitable for high-resolution      measurement of key gases such as CH₄ and NH₃.

• Photoacoustic Spectroscopy and Fluorescence Quenching      Technology: Optimizes the detection path for      gas characteristics such as CO and N₂O, enabling continuous monitoring without a physical reference      cell and improving data stability.

2. Dynamic Gas Chamber Design for Complex Field Conditions

• Automatic Opening/Closing Gas Chamber + Pressure Compensation      Device: Can operate stably in a wide      temperature range of -30°C to 40°C and an altitude of 0-1000 meters.      Equipped with a standard aluminum alloy low-greenhouse-effect respiration      chamber, it is suitable for multiple scenarios such as land, lakes,      swamps, and paddy fields, and can even be used in extreme environments      like gobi deserts and peatlands.

• 64-Channel Automatic Patrol Monitoring System: Supports flexible configuration of 8-64-point samplers, with      a channel switching time of <3 seconds. A single person can manage a      large-scale monitoring network, significantly improving field operation      efficiency.

  
  

III. Portable Integrated Design: Simplifying Operation Processes and Unleashing Research Efficiency

1. Lightweight Body for Flexible Deployment in All Scenarios

• Portable Integrated System:      Built-in 14.4V lithium battery can work continuously for 10 hours and      supports external solar power supply, meeting the needs of long-term field      operations in power-free environments.

• Military-Grade Protection Configuration: Optional waterproof, dustproof, and shock-resistant field      laptops, paired with a 7-inch color touchscreen (supporting 10-inch      military-grade screen expansion), ensuring stable operation even in harsh      conditions.

2. Intelligent Data Management for Unblocking Research Chains

• Multi-Mode Data Transmission:      Supports RS232/485, TCP/IP, USB, and GPRS/4G wireless transmission. The      supporting software has functions such as data storage, curve drawing, and      map-based positioning (requires a GPS module), and can generate visual      reports with one click to assist in the rapid transformation of research      achievements.

• Modular Expansion Capability: Can be connected to soil porosity and humidity sensors as needed, flexibly  adapting to various experimental designs such as closed/open/flow   injection. It also supports the BaPS method (soil      nitrification/denitrification experiments) and the SIR substrate-induced respiration method (ISO 14240-1 standard), deeply meeting international cutting-edge research needs.

  
  

IV. Diverse Application Scenarios: From Laboratories to the Field, Guarding Every Degree of the Ecology

• Ecological Environment Research:  Monitoring greenhouse gas flux in lakes and swamps, evaluating soil      microbial biomass, and analyzing vegetation carbon sink capacity to      provide basic data for climate change research.

• Agriculture and Animal Husbandry: Optimizing farmland fertilization efficiency (NH₃/N₂O emission      monitoring), preventing and controlling livestock breeding pollution, and      calculating paddy field carbon footprints to promote the transformation of green agriculture.

• Pollution and Industrial Monitoring: CH₄ leakage  early warning in landfills, real-time monitoring of toxic gases in chemical parks, and wetland restoration effect evaluation to build a solid environmental safety defense line.
