FourinOne Multi Gas Detector – Reliable Safety Monitoring for Hazardous Environments Key Features and Benefits: 1. Comprehensive Gas Detection Detects four types of gases: • EX (0–100% LEL) for combustible gases • H2S (PPM) for hydrogen sulfide • O2 (0–30% VOL) for oxygen level monitoring • CO (PPM) for carbon monoxide Ensures early warning and enhanced worker safety when gas levels reach dangerous thresholds. 2. Fast and Clear Alerts Four alarm methods: real human voice prompt, 120decibel audible alarm, vibration, and bright warning light. Alerts activate within 30 seconds of detecting hazardous levels, giving workers time to respond. 3. EasytoRead LCD Display Clear, bright LCD screen shows reliable readings at a glance. Designed for underground construction, confined spaces, and industrial environments where visibility is critical. 4. LongLasting Power Equipped with a 1800mAh capacity lithium battery for extended use without frequent recharging. 5. Accurate and Ready to Use Factory calibrated for immediate operation out of the box. Includes calibration cap and compatibility with plastic tube for precise measurement when introducing test gas. 6. Durable, FieldReady Design Constructed from strength ABS with nonslip grip rubber for rugged use. Compact size and integrated clip allow secure attachment to clothing or belts. Resistant to shocks, dust, water, and explosions, ensuring reliability in harsh environments. 7. Adjustable Alarm Thresholds Thresholds for all four gases can be customized within their measuring ranges to suit specific job requirements and avoid unnecessary alerts in lowoxygen or enclosed spaces. Typical Applications: Underground construction or tunneling projects where dangerous gas buildup is a risk. Confined space work such as tanks, silos, or utility vaults, where rapid detection is vital. Oil and gas operations, chemical plants, or industrial manufacturing environments prone to gas leaks. This multi gas detector combines advanced technology, durable materials, and userfriendly operation to provide dependable protection for workers in demanding and hazardous conditions.
