SYCON 2702 en L

Summary

Product Identification

The SYCON 2702 is an online analyzer that automatically determines water parameters using the colorimetric titration method. It analyzes one parameter at a time, with the parameter and measuring range determined by the specific indicator used.

• Air Humidity: 20 – 90 % RH (without ice or condensation)

Feed Water

• Inlet Water Pressure:
  • Minimum: 0.5 bar
  • Maximum: 5 bar
  • Recommended: 1 - 2 bar
• General Inlet Water Quality: Clear, colourless, free of solids, and without gas bubbles.
• Specific Water Quality Requirements for Measuring Water Hardness:
  • pH: 4 - 10
  • Iron: < 3 ppm
  • Copper: < 0.2 ppm
