   Product Detail


This competitively-priced, dual channel, dual display pH/conductivity meter is easy to set up and use while providing reliable, accurate conductivity, resistivity, salinity, TDS and temperature measurements for soil and water analysis applications. The rugged meter accepts both 4-electrode and 2-electrode cells and offers a full complement of GLP-related features—including available 21 CFR Part 11 software option.

Optional 1 to 5 point calibration for pH and conductivity ensures accuracy even at extremes of concentration. SMART STABILITYTM and SMART AVERAGINGTM functions simplify the measurement process. You can record and store up to 10 setup parameters and calibrations.

Additional Features: 

  • Bright LCD display with ready indication
  • Convenient built-in Quick-Start Guide
  • Meets all U.S. Pharmacopeia (USP) requirements
  • Automatic or manual temperature compensation
  • IP54 dustproof and splashproof
  • BNC pH electrode and mini DIN locking conductivity probe connectors
  • Automatic or manual pH calibration with 1 to 5 calibration points
  • Auto-buffer-recognition of DIN and NIST/US buffers; automatic or manual temperature compensation
  • Advanced self-tests on meter operation, self-diagnostics
  • CE, CSA, UL, TÜV and FCC Class A limits approved
  • Universal power adapter for worldwide operation
  • Includes certificate of calibration
  • Three-year replacement warranty.
