   Product Detail


This waterproof, battery-operated pH/DO meter stands up to the most demanding water analysis applications and delivers over 2,000 hours of continuous operation. Convenient Quick-Start Guide is located on the back of the meter to make the unit easy to operate in the field. 

The rugged meter displays DO concentration or percent DO Saturation and offers a full complement of GLP-related features—including available 21 CFR Part 11 software option. It offers enhanced stability indicators, salinity correction and automatic barometric pressure compensation—as well an auto-read/hold function, SMART STABILITYTMand SMART AVERAGINGTM.

A unique feature allows meter and probe calibration to a Winkler Titration for those needing to correlate measurements to Biological Oxygen Demand (BOD) readings to Winkler methods. You can record and store up to 10 setup parameters and calibrations—a valuable feature for multi-user labs. Download additional methods and software updates via the Web.

Additional Features: 

  • Balanced comfortable handling
  • Bright, backlit LCD display with ready indication
  • Automatic barometric pressure compensation
  • Stores up to 10 methods with password protection
  • Uses polarographic DO probe
  • IP67 waterproof (may be immersed for up to one hour with no water incursion)
  • Waterproof BNC pH electrode and waterproof mini DIN locking DO probe connectors
  • Automatic or manual pH calibration with 1 to 5 calibration points
  • Recognizes NIST, US and manual buffers; self-diagnostics
  • GLP IQ/OQ included
  • Optional USB outputs
  • CE, CSA, UL, TÜV and FCC Class A limits approved  
  • Three-year replacement warranty.
