Product Description
Advanced Portable Oxygen (O2) Detector for Industrial Safety
The HNAG900 portable oxygen detector is a professional-grade safety instrument designed for the real-time and accurate measurement of O2 concentration in harsh industrial environments. Whether you are operating in confined spaces, chemical plants, or underground pipelines, this device guarantees rapid response (T90 < 10S) and reliable leak detection. Certified with an Ex ib ll CT4 Gb explosion-proof grade and IP65 protection, it withstands the toughest operational conditions.
High-Precision Electrochemical O2 Sensor & Flexible Ranges
At the core of the HNAG900 is a highly sensitive electrochemical O2 sensor, offering outstanding stability and a lifespan of up to 3 years. To meet diverse industry requirements, this pump suction O2 meter supports customized detection ranges, including 0-5% Vol, 25% Vol, 30% Vol, and 0-100% Vol. The built-in adjustable pump efficiently draws air samples from hard-to-reach areas using the included 27cm bendable metal probe.
Smart Interface & Multi-Gas Expandability
Equipped with a brilliant 3.5-inch TFT color screen (480*320 resolution), the device provides crystal-clear visibility of real-time concentrations, historical curves, and alarm statuses. While primarily an O2 gas monitor, the HNAG900's modular design allows it to be expanded to detect up to 6 different gases simultaneously. The interface supports easy switching between single-gas curve graphs and multi-gas data displays.
Powerful Data Logging & PC Export
Data management is seamless with the HNAG900. It features a massive internal memory capable of storing up to 100,000 data entries and 1,000 alarm records. The storage interval is highly customizable. Safety managers can easily track historical data and export it via the USB interface to a computer to generate comprehensive safety reports.
Next-Generation Wireless Transmission (IoT Ready)
Modern industrial safety demands connectivity. This industrial oxygen detector goes beyond local two-level alarms (High/Low) by supporting advanced wireless transmission modes. Depending on your facility's infrastructure, the detector can be integrated with Custom 4G/5G upload, LoRa P2P for connecting to Gas Alarm Controllers, or Bluetooth for instant receipt printing.
Rugged Design & Complete Accessories
Powered by a massive 5400mAh lithium battery, the device ensures ultra-long standby times essential for long shifts. Every unit is packaged in a heavy-duty aluminum alloy enclosure, providing maximum protection during transport to rugged sites like steel mills or thermal power plants.
