Portable 6-in-1 Gas Detector for H2S CO2 NH3 VOC O2 CH4

6-in-1 Pump Suction Gas Detector: Your All-in-One Industrial Safety Solution

Worker safety is the foundation of industrial operations. Our 6-in-1 portable pump suction gas detector is designed with a people-first safety philosophy, enabling frontline operators and safety managers to monitor multiple gas hazards simultaneously in real time. Whether for confined space entry, daily site inspection or leak detection, this device delivers reliable gas concentration data to protect personnel from toxic gas exposure, oxygen deficiency and combustible gas explosion risks.

Simultaneous 6-Gas Detection for Full-Spectrum Risk Coverage

Unlike single-gas detectors that require multiple devices for comprehensive monitoring, this unit integrates detection for 6 common industrial gases in one handheld device, significantly improving inspection efficiency and reducing equipment carrying burden. It covers toxic gas, combustible gas and oxygen deficiency risks in a single test, eliminating the need to switch devices back and forth on site.

Detected Gas Types & Core Measurement Ranges

Hydrogen sulfide (H2S): 0 - 100 ppm

Carbon dioxide (CO2): 0 - 5000 ppm

Ammonia (NH3): 0 - 100 ppm

Volatile organic compounds (VOC): 0 - 100 ppm

Oxygen (O2): 0 - 30% VOL

Methane (CH4): 0 - 100% LEL

Wide Range & High-Purity Detection Capability

The detector supports wide measurement ranges up to 100% VOL for specific gas types (such as helium), enabling high-precision concentration detection for high-purity gas scenarios. It is suitable for helium filling verification, protective gas atmosphere confirmation and quality control in high-purity gas production, helping users accurately grasp gas purity and ensure process quality.

The real-time concentration change curve function allows users to visually observe the dynamic change trend of gas concentration, which is convenient for leak location and process parameter adjustment.

Pump Suction Sampling: Access Hard-to-Reach Areas with Precision

Equipped with a built-in sampling pump and top-mounted gas probe, this detector adopts active pump suction sampling technology, which solves the problem of difficult gas collection in closed, narrow or long-distance spaces.

Compared with natural diffusion detectors, the pump suction design enables:

Long-distance sampling inside pipelines and ducts

Gas detection in deep confined spaces without personnel entry

Accurate fixed-point leak detection for equipment and pipe joints

Faster response time and more stable concentration readings

 

Ergonomic Handheld Design for Effortless On-Site Inspection

Built for mobile field work, the detector features a compact, lightweight body with an ergonomic grip that supports stable one-handed operation, freeing up the other hand for climbing, recording or other work tasks.

Intuitive Physical Button Operation

The device is equipped with clearly labeled physical function keys, including return, power, menu and direction navigation keys. Operators can quickly switch interfaces, set parameters and view historical data even while wearing work gloves, without complex touchscreen operations.

High-Definition Color Display for Clear Readability

The high-brightness color screen ensures clear visibility of readings even in strong outdoor sunlight or dim underground environments. The interface adopts a modular layout, with gas concentration, status bar, battery level and time information arranged in a clear hierarchy, so operators can grasp on-site gas conditions at a glance.

Real-Time Monitoring & Graded Alarm System for Frontline Protection

With high-precision gas sensors, the detector updates concentration readings in real time, and triggers alarms immediately when gas levels exceed preset thresholds, providing early warning for on-site personnel to take protective measures or evacuate.

Multi-Level Graded Alarm Mechanism

The system supports low alarm and high alarm levels for each gas, with independent threshold settings for different working scenarios. For oxygen detection, the device is preset with low oxygen alarm thresholds, which can quickly identify oxygen deficiency risks in confined spaces and prevent suffocation accidents.

The screen clearly marks "Normal" and "Low Alarm" status for each gas channel. Alarms are delivered through sound, light and screen prompts simultaneously, ensuring that operators can perceive danger in noisy, dark or visually obstructed work environments.

Data Logging & Traceability for Compliance Management

The detector automatically records gas concentration data with accurate time stamps, supporting storage of massive historical data. Users can directly view maximum, minimum and average concentration values over a selected period on the device, and export data for safety report preparation and compliance audit.

This data management function helps enterprises establish complete gas safety records, trace abnormal gas events, and optimize safety management systems in accordance with industrial safety regulations and standards.

Wide Adaptation to Multi-Industry Industrial Safety Scenarios

Thanks to its comprehensive gas detection capability and portable design, this detector is widely used in various industries where gas hazards exist.

Confined Space Entry Safety

For sewers, septic tanks, storage tanks, reaction kettles, underground pipe galleries, mines and ship cabins, the detector is used for pre-entry gas qualification testing and continuous monitoring during operation, to prevent poisoning, suffocation and explosion accidents in closed spaces. It serves as an essential safety access tool for confined space operations.

Municipal & Environmental Sanitation

In sewage pipe network maintenance, landfill sites and sewage treatment plants, the device monitors hydrogen sulfide, methane and ammonia generated by anaerobic decomposition of organic matter, protecting the safety of sanitation workers and operation personnel.

Chemical & Manufacturing Industry

For petrochemical plants, spraying workshops, printing factories and rubber/plastic processing facilities, the detector is used for daily patrol of toxic gases and VOC leak detection, to prevent occupational health damage and fire and explosion risks caused by volatile gas accumulation.

Livestock & Agriculture

In livestock and poultry farms and silos, the device monitors ammonia concentration produced by manure fermentation, to improve the working environment of breeders and ensure the healthy growth of livestock and poultry.

Gas & Energy Sector

For natural gas pipeline patrol and underground coal mine operations, the detector detects methane leakage in real time, monitors the lower explosion limit, and provides early warning of gas explosion risks.

Reliable Gas Detection for Every Industrial Safety Scenario

Our 6-in-1 portable pump suction gas detector combines multi-gas synchronous detection, pump suction sampling, ergonomic portable design, real-time graded alarm and systematic data management functions, making it a cost-effective gas safety tool for industrial enterprises, municipal departments and engineering teams.

With a people-first design concept and reliable detection performance, it helps you build a solid line of defense for on-site gas safety.
