ONETEST-G40 Voice-Prompt Multi-Gas Detector

The ONETEST-G40 is a professional 4-in-1 gas detector designed for continuous monitoring of combustible gas, oxygen (O2), hydrogen sulfide (H2S), and carbon monoxide (CO) concentrations in hazardous environments. Equipped with high-quality imported sensors and advanced microcomputer control technology, it delivers exceptional sensitivity and outstanding repeatability.

Key Features

• Real Human-Voice Alarm: Bilingual (Chinese/English) voice prompts clearly announce gas hazards, complemented by vibration and visual light alarms for triple-layer safety notification.
• 4-in-1 Detection: Simultaneously monitors combustible gas (0-100%LEL), oxygen (0-30%VOL), hydrogen sulfide (0-100PPM), and carbon monoxide (0-1000PPM).
• Explosion-Proof Certified: Meets GB 15322.1-2019, GB 12358-2006, GB/T 3836.1-2021, and GB/T 3836.4-2021 standards for safe operation in hazardous locations.
• Dot-Matrix LCD Display: Clear bilingual interface for quick access to gas readings and device status.
• Rugged ABS Housing: High-strength engineering plastic with excellent impact resistance and premium finish, weighing only 205g.
• Customizable Gas Sensors: Supports catalytic combustion, electrochemical, infrared, or PID detection principles. Additional gas types available upon request including ozone (O3), chlorine (Cl2), ammonia (NH3), and more.

Applications
