This waterproof, battery-operated conductivity meter stands up to the most demanding soil and 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. In addition to pH, the rugged meter displays conductivity, resistivity, salinity, TDS and temperature measurements and offers a full complement of GLP-related features—including available 21 CFR Part 11 software option. It accepts both 4-electrode and 2-electrode cells.
SMART STABILITYTM and SMART AVERAGINGTM functions simplify the measurement process. You can record and store up to 10 setup parameters and calibrations—a valuable feature for multi-user labs.
