Pharma Refractometers – PR23AC

 

kpatentsAn all-purpose refractometer for large pipe and vessel installations. Installation through a flange or a clamp connection. Area classification Zone 2 (Class I, Div. 2); Intrinsically safe process refractometer PR-23-GP-IA Area classification Zone 0 and Zone 1.

  • Universal calibration of each sensor: All sensors are freely interchangeable.
  • Full measurement range Refractive Index (nD) 1.3200 – 1.5300, which
    corresponds to 0-100 Brix/Conc.
  • Meets 3A Sanitary Standard and tested for CIP cleanability according to EHEDG.
  • Withstands CIP cleaning.
  • Completely digital system: particles and bubbles do not affect operation or accuracy.
  • Patented CORE-optics: no drift, no re-calibration, no mechanical adjustments.
  • Includes an Ethernet communication solution for data-logging. Together with the user's own
    procedural and administrative user controls this facilitates electronic data records for FDA 21
    CFR Part 11 adherence.
  • Effective heat transfer and isolation using Teflon® and ceramics in the sensor provide safe
    operation also in higher process temperatures (max. 130 °C/266 °F.
  • Fast process temperature measurement by built-in Pt1000 and automatic temperature
    compensation.
  • Calibration and accuracy traceability with easy on-site instrument verification using standard
    Refractive Index liquids.
  • ATEX approved for Zone II, area classification EX II 3 G EEx nA II T4.
  • ATEX approved for Zones 0 and 1, area classification ATEX II 1G Ex ia IIC T4 (only Intrinsically
    safe PR-23-AC-IA with single sensor transmitter STR ).
  • FM approved for Class I, Div. 2, Groups A, B, C and D, T6.
  • CSA certified for Class I, Div. 2, Groups A, B, C and D, T4.
  • cCSAus certified for Electrical Safety, Sensor: Class I, Pollution Deg. 3; Transmitter: Class I,
    Pollution Deg. 2; Installation Cat. II.
