What Is an Oxygen Detector and Why It Matters – Meet the DM68A

Oxygen is essential for life, but in many enclosed or poorly ventilated environments, oxygen levels can decrease without warning—posing serious health and safety risks. An oxygen detector is a specialized device that continuously measures the oxygen (O₂) concentration in the air, helping users detect hypoxia (oxygen deficiency) before it becomes dangerous.

When Should You Use an Oxygen Detector?

Oxygen detectors are widely used across industrial, commercial, and residential settings, including:

• Workshops, factories, confined spaces (like basements or tanks)
• Hospitals, laboratories, and research facilities
• Indoor spaces with poor ventilation
• High-altitude areas
• Emergency rescue or hazardous material handling

Oxygen levels below 18.0% Vol can impair physical and mental performance; levels below 10% can be life-threatening. Continuous monitoring is essential for ensuring a safe environment, especially where ventilation is limited.

Why Choose the DM68A Oxygen Detector?

The DM68A is a compact, rechargeable, and highly accurate oxygen detector designed for everyday air quality protection.

• Detection Range: 0 – 30.0% Vol
• Measurement Accuracy: ±0.1% Vol (electrochemical sensor)
• Sampling Time: 1.5 seconds (real-time updates)
• Visual Alert System:
    ✔ Green: >18.0% (Good)
    ✔ Yellow: 10.1% – 18.0% (Slight Hypoxia)
    ✔ Red: 0 – 10.0% (Dangerous)
• Additional Metrics: Temperature (-10°C to 50°C), Humidity (20%–85%)
• Display: Large, intuitive LCD showing O₂, temperature, humidity, time
• Alarm Function: Built-in buzzer alerts when oxygen drops below threshold
• Portable & Rechargeable: 2000 mAh lithium battery, USB charging
• User-Friendly Settings: Adjustable alarm levels, display brightness, logging interval, and language (English/Chinese)

With sound alarms, graphical history, and easy controls, even non-professionals can operate it confidently.

Protect your air. Protect your health.

The DM68A isn’t just a tool—it’s a safeguard. Whether you’re a worker in confined spaces, a lab technician, or a concerned homeowner, this device helps you detect oxygen deficiencies before they become critical.
