TRACE OXYGEN GAS ANALYZER

उत्पाद वर्णन

Measurement Parameters

• Oxygen Range: 0.1 ppm to 25% (depending on application requirements)
• Resolution: Down to 0.01 ppm for high-precision applications
• Accuracy: ±1-2% of reading or ±0.1 ppm, whichever is greater
• Response Time: 10-30 seconds to reach 90% of final reading

2. Sensor Type

• Electrochemical Sensor: Common for low-ppm detection
• Zirconium Oxide Sensor: Used for wide dynamic range and high-temperature tolerance
• Laser-Based Technology (TDLAS): For rapid, interference-free measurement (optional in some high-precision models)

3. Physical and Environmental Specifications

• Operating Temperature: Typically 0C to 45C (some models support higher ranges)
• Storage Temperature: -20C to 60C
• Relative Humidity: 0-95% RH, non-condensing
• Pressure Range: Often operates up to ±1 bar (some models can handle high-pressure applications)

4. Display and Interface

• Display: LCD or touchscreen with backlighting for easy reading
• Data Logging: Stores up to thousands of measurement points; may support external storage (e.g., SD card)
• Output Signals: 4-20 mA analog output, MODBUS, RS-232/485 digital output
• Alarms: Adjustable high/low alarm setpoints with visual and audio notifications

5. Power and Battery

• Power Supply: 100-240 VAC or 24 VDC options
• Battery Backup: Available in portable models, typically up to 8-10 hours

6. Calibration and Maintenance

• Calibration: Typically factory-calibrated, with periodic calibration recommended (intervals vary based on model)
• Calibration Gas: Requires certified trace oxygen calibration gases (0.1-10 ppm O in N or other mixtures)
• Maintenance: Minimal, with annual or biannual sensor checks or replacement for electrochemical sensors

7. Certification and Compliance

• Compliance Standards: ISO, ASTM, or specific industry standards for trace oxygen measurement
• Safety Ratings: ATEX, IECEx, or other certifications for operation in hazardous environments (optional)
• Environmental Standards: Designed to meet regulatory requirements for industries like pharmaceutical, petrochemical, and semiconductor

These specifications cover the basics, though specific models can vary depending on application needs, sensitivity, and environmental conditions.
