Product Description
HNAG920-HCN Portable Hydrogen Cyanide Gas Detector Overview
The HNAG920-HCN is a high-precision portable single gas detector designed for continuous monitoring of hydrogen cyanide (HCN) concentration in industrial environments. Built with advanced electrochemical sensing technology, it delivers accurate, real-time HCN concentration readings to protect workers from toxic gas hazards in confined spaces, chemical plants, and other industrial sites.
Core Detection Performance
High-Precision Electrochemical HCN Sensing
Equipped with a professional electrochemical sensor, the HNAG920-HCN gas detector delivers fast response and high accuracy for hydrogen cyanide detection. It supports 3 optional measuring ranges to adapt to different industrial scenarios: 0-10(50)ppm, 0-50(100)ppm, and 0-1000(2000)ppm. The sensor features strong anti-interference performance and long service life, ensuring reliable long-term operation in harsh working conditions.
Dual Sampling System: Pump Suction + Diffusion
Unlike standard diffusion-only gas detectors, the HNAG920-HCN adopts an innovative dual sampling design that integrates both pump suction and diffusion sampling modes. The built-in pump can actively draw gas samples from hard-to-reach areas, pipelines, and confined spaces, while diffusion mode is suitable for daily personal portable monitoring. Users can freely switch between modes according to on-site working requirements.
User-Friendly Design for Industrial Field Work
180° Auto-Rotating Color Display
The detector features a 2.0-inch high-definition color LCD screen with 180° automatic rotation function. No matter how you hold the device in special working positions (such as overhead detection or narrow space operation), the screen will automatically rotate to ensure easy reading of HCN concentration, alarm status, temperature and humidity data. The clear interface displays real-time values, TWA/STEL values, and alarm thresholds at a glance.
Multi-Level Alarm System & One-Key Emergency Alarm
The HNAG920-HCN is designed with a comprehensive triple alarm system: sound buzzer, LED flashing lights, and vibration alarm (optional), ensuring that alarms are noticeable even in noisy and low-visibility industrial environments. It is also equipped with an independent one-key alarm button for emergency help, supporting drop alarm function for worker safety protection. Users can set low and high alarm thresholds according to on-site safety standards.
Data Management & Wireless Connectivity
Large-Capacity Data Storage & USB Export
This HCN gas analyzer has a built-in large-capacity data storage system, which can record up to 120,000 historical detection data and 30,000 alarm event records. With the Type-C USB interface, users can directly export data to a PC in table format without installing any additional software, making it easy for data analysis, report generation and safety archive management. The Type-C port also supports 5VDC charging for convenient power supply.
Multiple Wireless Communication Options
To meet the needs of intelligent safety management, the detector supports multiple wireless transmission methods: 4G, WiFi, Bluetooth, and LORA. Real-time HCN detection data can be synchronized to the cloud monitoring platform and mobile APP, allowing managers to remotely monitor on-site gas conditions. It also supports Bluetooth printing for on-site data output and work record generation.
