【English Version】
The EM-20/NO Nitrogen Dioxide Gas Detector is a professional monitoring device designed for industrial environments, ecological research, and laboratory applications. Utilizing electrochemical sensing technology, it provides real-time detection of nitrogen dioxide (NO₂) concentration in ambient air, delivering reliable data support for environmental safety management.
The detector features a high-precision sensor capable of accurate measurement within 0-20ppm range, with detection resolution down to 0.1ppm. The built-in color LCD display shows real-time concentration values and dynamic trends through intuitive graphical interfaces. When gas concentration exceeds preset thresholds, the device activates audible-visual alarms and supports external alarm connections.
With compact dimensions and lightweight construction (under 300g), the portable design incorporates anti-slip housing and swivel hooks for flexible deployment. The 4000mAh lithium battery provides over 12 hours of continuous operation, complemented by USB-C fast charging capability. Internal memory stores up to 2000 data records, supporting data export via Bluetooth or USB cable for further analysis.
Industrial applications include process monitoring in chemical plants, metal treatment facilities, and emission control systems. Environmental protection applications encompass urban air quality assessment and indoor environment evaluation. The laboratory-optimized version meets rigorous research requirements for precise gas concentration tracking.
Key advantages include modular sensor design for user-replaceable components, intuitive menu navigation for parameter customization, and IP65-rated housing for reliable performance in humid/dusty conditions. Each unit undergoes comprehensive calibration to ensure measurement accuracy before delivery. The streamlined interface requires minimal training, while maintenance alerts notify users when sensor replacement or recalibration is recommended.
Dual operation modes cater to different usage scenarios: Continuous monitoring mode for long-term observation and manual sampling mode for spot checks. Optional accessories include telescopic probes for confined space detection and waterproof cases for outdoor applications. Compatible with Windows/MacOS analysis software, the device facilitates comprehensive data visualization and report generation.
