Operating in confined spaces like storage tanks, underground pipelines, or narrow maintenance shafts poses significant risks. Our HNAG900 portable gas detector is engineered to provide real-time, accurate gas concentration monitoring to prevent oxygen deficiency, toxic exposure, or explosion hazards.

• Multi-Gas Detection: Supports simultaneous detection of up to 6 gases, including O2, CH4, H2S, and CO, ensuring comprehensive safety coverage.
• High-Precision Sensing: Equipped with a 32-bit microprocessor for rapid response times (T90 < 10S) and high measurement accuracy.
• Rugged Design: IP65 protection grade ensures durability in harsh industrial environments.
• Advanced Visualization: The 3.5-inch TFT screen displays real-time concentration curves, alarm status, and historical data.
| Feature | Specification |
| Detection Principle | Electrochemical/Catalytic Combustion |
| Sampling Method | Pump Suction (Adjustable speed) |
| Battery Capacity | 5400mAh (Long standby) |
| Data Storage | 100,000 entries |
| Protection Grade | IP65 |

Our device is not just a monitor; it is a vital tool for industrial process control, environmental monitoring, and hazardous site protection. With Lora wireless transmission support and easy data export via USB, it offers flexibility for both daily inspections and long-term research.
• Calibration: Regularly calibrate the sensors every 6-12 months to maintain measurement accuracy.
• Proper Care: Avoid blocking the pump suction port. If used in high-humidity environments, ensure pre-filtering and dehumidification.
• Safety First: Always charge the device in safe areas using compliant 5V/2A chargers.
