Smart Sensor ST8100B / AT8100 Handheld Oxygen ($O_2$) Gas Detector – Personal Portable O2 Analyzer with Ambient Temperature Display & Audio-Visual Hazard Alarms The Smart Sensor ST8100B / AT8100 is a professional personal safety instrument engineered to track real-time atmospheric Oxygen ($O_2$) concentration levels, isolate hypoxic safety conditions, and protect personnel in high-risk utility sectors. Driven by a fast-responding stabilized electrochemical gas-specific sensor core, this handheld monitor covers an essential safety span of $0 \text{ to } 30\% \text{ VOL}$. Featuring customizable high/low threshold alarms, it provides immediate audio-visual indicators if oxygen levels deviate from safe atmospheric baselines ($20.9\%$).

Key Features:

  • Stabilized Electrochemical Core Sensor: Delivers excellent repeatability, highly precise tracking, and quick reaction windows across targeted oxygen molecular variants.
  • 0 to 30% Vol Measurement Range: Perfectly tuned to monitor commercial indoor air profiles, highlighting oxygen enrichment or life-threatening oxygen depletion levels down to a $0.1\%$ resolution.
  • Smart Audio-Visual Hazard Alarm Staging: Equipped with an intensive sound buzzer and bright flashing LED alert mechanisms that activate instantly when user-configured high/low limits are breached.
  • Integrated Environmental Multi-Tracking: Large backlit segment LCD screen displays live oxygen concentration percentages alongside active ambient temperature parameters ($-20^\circ\text{C} \text{ to } 50^\circ\text{C}$).
  • Rechargeable Battery & USB Interface: Built-in high-capacity lithium-ion cells with modern USB charging support eliminate continuous dry-cell replacement expenses on long shifts.
  • Ultra-Compact Pocket Chassis: Designed for ergonomics and portable convenience, weighing just under 170g for single-handed testing on factory floors, inside tool belts, or during emergency field deployments.

Product Overview

Safeguard operational workflows, guarantee occupational health compliance, and handle pre-entry confined space staging with the Smart Sensor ST8100B / AT8100 Personal Oxygen Gas Detector. Gas leaks or heavy nitrogen/argon displacement can deplete standard breathable oxygen concentrations instantly, posing a severe hazard before human physical senses notice a shift.

The ST8100B/AT8100 remedies this safety gap by delivering rapid continuous sampling with an impressive T90 response velocity of less than 15 seconds. Outfitted with automated low-battery alerts, an easy-to-use button configuration, and automatic calibration routines upon boot-up, this instrument provides an essential field toolkit for underground pipeline inspectors, chemical plant operators, HVAC engineers, and laboratory safety technicians.
