The ABB IEPAS02 is part of the IEPAS (Ion Exchange Potential Analysis System) series, typically used for water quality monitoring, particularly in measuring ion concentration (e.g., nitrate, ammonia, etc.) in water. Below are the general technical parameters for the ABB IEPAS02 analyzer:

General Specifications

• Measurement Principle: Ion-selective electrode (ISE) technology
• Measured Parameters: Typically Nitrate (NO₃⁻), Ammonium (NH₄⁺), Potassium (K⁺), etc.
• Measurement Range:
  • Nitrate (NO₃⁻): 0.1 – 1000 mg/L (or ppm)
  • Ammonium (NH₄⁺): 0.1 – 1000 mg/L (or ppm)
  • Potassium (K⁺): 0.1 – 1000 mg/L (or ppm)
    (Exact ranges may vary depending on sensor configuration)
• Accuracy: Typically ±2% of reading or ±0.1 mg/L (whichever is greater)
• Response Time: < 5 minutes (for 90% of final value)

Operating Conditions

• Sample Flow Rate: 50 – 300 mL/min
• Temperature Range: 0 – 40°C (operating), -20 – 60°C (storage)
