Product Description
HNAG920-CL2 Portable Chlorine Gas Detector Design & Core Features
Ergonomic Handheld Design for Field CL2 Detection
The HNAG920-CL2 features an ergonomic handheld structure with a rugged PC+TPU housing, which is drop-resistant, dust-proof and adaptable to complex industrial field environments. Its compact size supports one-handed operation and easy portability, effectively improving the efficiency of on-site gas inspection and emergency response.
Full Set with Protective Aluminum Carrying Case
Each detector is equipped with a high-strength aluminum alloy carrying case, which provides all-round shockproof and moisture-proof protection during transportation and storage. The case is designed with a durable latch and comfortable handle, making it convenient for workers to carry the device to various outdoor and industrial work sites.
Detailed Structure & Core Components of CL2 Gas Monitor
This CL2 gas monitor integrates multiple functional modules with a reasonable structural layout, ensuring stable performance, convenient operation and easy daily maintenance.
High-Precision Sensor & Dual Sampling System
The detector adopts a high-sensitivity electrochemical CL2 sensor, with a diffusion sampling inlet on the front and a pump suction sampling port with a water trap filter on the top. The built-in sampling pump can actively extract gas samples, especially suitable for gas detection in confined spaces, pipelines and other hard-to-reach areas. The water trap filter effectively blocks moisture and dust, extending the service life of the sensor.
Multi-Mode Alarm System & Independent One-Key Alarm
The device is equipped with top and bottom dual LED alarm lights, a high-decibel buzzer, and an independent one-key alarm button on the side. When the CL2 concentration exceeds the preset threshold, the red LED flashes and the buzzer triggers a loud alarm; the green LED stays on during normal operation. The one-key alarm button allows users to send an emergency alarm signal immediately in dangerous situations, fully guaranteeing personnel safety.
HD Color LCD Display & Intuitive Keypad Operation
Equipped with a 2.0-inch high-definition color LCD screen (320*240 resolution), the detector clearly displays real-time gas concentration, temperature, humidity, battery level and working status. The 5-key operation panel (power/return, menu/confirm, up/down adjustment) supports simple and intuitive operation, and can be used normally even with work gloves.
Convenient Type-C Interface for Charging & Data Export
The bottom of the detector is designed with a universal USB Type-C interface, which integrates charging and data transmission functions. The built-in large-capacity rechargeable battery provides long-lasting battery life, meeting the needs of long-term outdoor work. Users can connect the device to a computer via a Type-C cable to export historical detection data for data analysis and work report generation.
Auto Screen Rotation for Special Working Scenarios
The HNAG920-CL2 is equipped with an intelligent auto screen rotation function, which can automatically rotate the display content by 180 degrees according to the placement direction of the device. This design allows users to read data easily in special working postures (such as overhead operation, inverted detection), greatly improving the convenience of use in complex and narrow working environments.
Multiple Wireless Connectivity & Intelligent Data Management
This CL2 gas detector supports 4G, WiFi, Bluetooth and LORA wireless transmission methods, realizing intelligent data management and remote monitoring, and adapting to the digital management needs of modern industrial safety.
Mobile APP Viewing & Bluetooth Printing
Users can view real-time detection data and historical records on their mobile phones through the matching APP, and remotely set alarm thresholds and device parameters. The detector also supports Bluetooth connection to a portable thermal printer, which can print on-site detection data and work reports, meeting the needs of on-site work record filing.
PC Monitoring Platform for Unified Management
The device can be connected to a computer monitoring platform via 4G or WiFi network, realizing remote real-time monitoring of multiple devices. Managers can view the location and detection data of each detector on the platform, and receive alarm information synchronously, which is convenient for unified safety management of the whole work site.
