Memosens CLL47E

Summary

Product identification

• Product name: Memosens CLL47E
• Product type: Contacting conductivity sensor for laboratory measurements and random sampling in the field
• Technology: Digital with Memosens 2.0 technology

Application

Designed for measurements where very diverse conductivities need to be measured within a single system. Suitable for sticky and viscous samples due to easy cleaning with mechanically polished surfaces.

Measuring principle

A 4-electrode system applies an alternating current via the outer electrodes and measures the voltage at the inner electrodes. This allows for reliable electrolytic conductivity determination, suppressing electrochemical effects at the electrodes.

Input

• Measured variables: Conductivity, Temperature
• Measuring ranges:
  • Conductivity: 5 µS/cm to 200 mS/cm (in relation to water at 25 °C)
  • Temperature: 0 to 100 °C (32 to 212 °F)
• Cell constant: k = 0.57 cm⁻¹
• Temperature compensation: Pt1000 (Class A according to IEC 60751)

Performance characteristics

• Cell constant uncertainty: 1.0 % (determined at factory)
• Measured error:
  • Conductivity:
    • 5 µS/cm to 1 mS/cm: ≤ 2 % of reading
    • 1 mS/cm to 200 mS/cm: ≤ 4 % of reading
  • Temperature: ≤ 1.0 K (in measuring range 0 to 100 °C)
• Repeatability:
  • Conductivity: ≤ 0.5 % of reading (in specified measuring range)
  • Temperature: ≤ 0.5 K
