Explosion-Proof Portable Micro Oxygen Analyzer—GPL-1200Ex

Technical Parameters

Principle: Super Galvanic electrochemical sensor.

Range: 0 ~ 10/100/1000ppm, 25% O₂, automatic/manual range.

Accuracy: 1% of the range (at normal temperature and pressure).

Resolution: 0.01 PPM.

Linearity: R-squared value >0.995.

Response Time: 10 seconds to reach 90%.

Recovery Time: 60 minutes from air (60 seconds) to 10ppm.

Sensor Life: >24 months (at 1000ppm).

Electrical Characteristics

Display: Large-screen LCD display,

★ Value Stability Line: The longer the line on the screen, the more unstable the value. When the value stabilizes, the line becomes a dot or disappears.

Control Keys: Five waterproof buttons for easy selection of power on/off, range, calibration, alarm, and system settings.

Output: 0 ~ 3V analog output (optional).

Power Supply: Standard non-rechargeable batteries, battery life 10 months.

Explosion-Proof: Intrinsically safe explosion-proof, explosion-proof rating: Class 1, Division 1, Groups A, B, C, D. IICT4.

Alarm: Low battery alarm.

★ Automatic shutdown function when the battery is extremely low to prevent damage from excessively low battery voltage.

Operating Conditions
