Product Description
HNAG920-O2 Portable Oxygen Gas Detector: Features, Design & Applications
The HNAG920-O2 is a professional industrial-grade single-gas oxygen concentration detector, designed for on-site safety monitoring in complex working conditions. It integrates high-precision sensing, intelligent alarm and wireless data management, widely used in petrochemical, mining, municipal and other fields.
High-Precision Oxygen Detection with Multiple Optional Ranges
Advanced Electrochemical Sensing Technology
The HNAG920-O2 adopts a high-performance electrochemical oxygen sensor, which has the advantages of high detection accuracy, fast response speed, strong anti-interference ability and good long-term stability. It can accurately detect oxygen concentration in the environment and trigger an alarm in time when the value exceeds the limit.
Customizable Detection Ranges
To meet the needs of different application scenarios, this O2 detector provides 3 optional detection ranges: 0-30% vol for conventional environmental oxygen detection, 0-100% vol for high-concentration oxygen scenarios, and 0-10000ppm for trace oxygen detection. Users can select the appropriate range according to actual working conditions.
User-Centric Industrial-Grade Ergonomic Design
180° Auto-Rotating Color LCD Display
Equipped with a 2.0-inch high-definition color LCD screen, the detector supports 180-degree automatic screen rotation. No matter the operator holds it upright or upside down in a special working position, the display data can be viewed normally, greatly improving the convenience of on-site operation. The interface clearly displays concentration value, alarm status, temperature, humidity and battery level at a glance.
Durable Housing & One-Key Emergency Alarm
The detector shell is made of PC + TPU composite material, which is drop-resistant, wear-resistant and dust-proof, suitable for harsh industrial environments. The side is designed with an independent one-key alarm button, which can quickly trigger sound and light alarm in emergency situations to call for help. Multiple LED indicator lights on the top and bottom are matched with a high-decibel buzzer to achieve three-dimensional alarm, which can be clearly perceived even in noisy environments.
Flexible Sampling Methods & Comprehensive Alarm System
The HNAG920-O2 supports diffusion sampling for daily conventional environmental detection; it also reserves a pump suction sampling port with a water trap filter, which can be matched with an external air pump to realize fixed-point sampling in pipelines and confined spaces.
The detector supports multi-level alarm settings including low alarm, high alarm, TWA and STEL. It adopts three alarm modes: sound, light and vibration. The alarm threshold can be customized according to safety specifications to ensure that potential oxygen deficiency or oxygen enrichment hazards are warned in the first time.
Smart Wireless Data Management & Traceability
Multiple Wireless Transmission Solutions
This oxygen detector is equipped with a variety of built-in wireless transmission modules: 4G / WiFi for remote real-time data upload to the cloud management platform; Bluetooth for connecting to mobile phone APP to view data and export reports on site; LORA for long-distance data transmission in factory parks and tunnel scenarios, realizing unattended online monitoring.
Data Logging & On-site Printing
The instrument has a built-in large-capacity data storage function, which can automatically record detection data with time stamps, supporting historical data query and export. It can also be connected to a Bluetooth thermal printer to print on-site detection reports, which is convenient for work record filing and on-site inspection.
Complete Package & Wide Industrial Applications
The product is equipped with a high-strength aluminum alloy protective box, which is shock-proof and drop-proof, easy to carry and store on site. It is widely used in:
Confined space operations (tunnels, pipelines, storage tanks, sewers)
Petrochemical, coal mining, metallurgy and pharmaceutical production sites
Municipal gas, fire emergency rescue, environmental monitoring
Agricultural greenhouses, aerospace and other scenarios requiring oxygen concentration detection
