ORP (Redox) measuring mode available (ORP electrode sold separately).
  • Highest Accuracy: ±0.002 pH± 1 digit
  • The Swiss Labsen 211 pH Combination Electrode ensures highly stable & accurate pH/temp. measurements
  • Quick and Easy 1 to 5 points auto calibration with calibration guide and reminder function (premixed standard solutions included)
  • Electrode's slope display shows the health of your electrode
  • The large backlit LCD displays pH and temperature simultaneously along with icons of stable readings and finished calibrations.
  • GLP Data management (500 groups of data storage) with USB data output

Premium pH electrode:

  • Equipped with the LabSen® 211 Combination pH Electrode made with Swiss sensor technologies and materials, featuring an impact-resistant and bubble-free sensor tip, and a long-life reference system; compatible with TRIS buffer.

Intelligent Functions:

  • Quick & Easy 1 to 5 Points Auto Calibration (7.00, 4.00, 10.01, 1.68, 12.45). The Smart Self-Diagnosis helps you conduct proper calibrations and monitor the condition of your probe with electrode's slope data display. The large clear LCD displays pH and temperature simultaneously along with icons of stable readings and finished calibrations.
  • GLP Data management (500 groups of data storage), USB data output and PC software support. Timing measurement/data logging mode and Smart calibration reminder function available.

Reliable Structure:
