Product Description
High-Precision Portable Pump-Suction 5-in-1 Gas Detector
The HNAG920-5H portable pumping and diffusion 5-in-1 gas detector is an advanced safety solution engineered for the real-time, highly accurate detection of gas concentrations and leaks in complex environments. Designed to monitor five critical gases simultaneously—LEL, CO, O2, H2S, and CO2—it utilizes a powerful combination of Electrochemistry, Catalytic Combustion, and Infrared NDIR detection principles to deliver exceptional measurement accuracy (±3% F.S) and rapid response times (T90 < 10S).
Dual Sampling Modes & Rugged Industrial Design
This versatile analyzer integrates both active pump-suction and passive diffusion modes into a single compact unit. The active pump efficiently draws distant air samples into the sensor chamber, while the diffusion mode is ideal for continuous personal monitoring. The rugged housing is constructed from impact-resistant PC+TPU using a rubber overmolding process, achieving an IP65 protection grade and an Ex ib II CT4 Gb explosion-proof certification for safe operation in hazardous petrochemical and mining sites.
Intelligent Safety Features: Fall Alarm & 180° Auto-Rotating Screen
Worker safety is prioritized through the inclusion of a highly sensitive fall alarm and a one-touch emergency alarm function, ensuring immediate alerts are triggered during accidents. The device is equipped with a vibrant 2.0-inch color LCD (320x240 resolution) that features an innovative 180° auto-rotating display, allowing operators to easily read concentration data, battery life, and alarm statuses from any angle.
Massive Data Storage & IoT Wireless Connectivity
The HNAG920-5H-Z is equipped with a 32-bit microprocessor capable of storing up to 120,000 historical data entries and 30,000 alarm records. Data can be seamlessly exported or deleted by connecting the external USB Type-C port to a computer. For modern IoT integration, the detector supports 4G, WiFi, Bluetooth, and LoRa wireless transmission modes, enabling real-time remote monitoring and cloud data synchronization across your facility.

Frequently Asked Questions (FAQ)
Q1: What gases can this multi-gas detector monitor at the same time?
A: This 5-in-1 device is configured to simultaneously monitor Combustible Gas (LEL), Carbon Monoxide (CO), Oxygen (O2), Hydrogen Sulfide (H2S), and Carbon Dioxide (CO2).
Q2: What is the advantage of having both pump-suction and diffusion modes?
A: The integrated design allows for versatile usage. The pump-suction mode actively draws distant air for rapid pre-entry testing in confined spaces, while the diffusion mode passively monitors the surrounding air, which is ideal for power-saving, continuous personal protection.
Q3: How does the Fall Alarm function protect workers?
A: The built-in fall alarm detects if the user has suffered a sudden drop or accident. It automatically triggers a loud visual and audible alarm to alert nearby personnel for swift emergency rescue.
Q4: Can I export the historical detection data to my computer?
A: Yes. The device features an immense storage capacity of 120,000 data entries and 30,000 alarm records. You can easily export this data by connecting the device to a PC via the USB Type-C interface.
Q5: Does the device support remote wireless monitoring?
A: Absolutely. To support smart industrial applications, the detector can transmit data wirelessly via 4G, WiFi, Bluetooth, or LoRa protocols, ensuring supervisors have real-time access to safety data.
