Labzee Portable Gas Detector is designed for on-site oxygen concentration monitoring, providing real-time results with a response time under 20 s. The electrochemical (EC) sensor measures 0–100% VOL oxygen at a working flow rate of 500 mL/min.

Its color LCD touch screen provides measurement display and calibration control for routine checks. A single-button design enables simple power operation during on-site testing.

Manufactured for oxygen monitoring in laboratories, mining, chemical manufacturing, and confined spaces, this oxygen gas detector supports environmental safety inspections and routine O2 gas assessment.
