The probe is constructed of PVC with 4 stainless steel rings that are corrosion resistant. The 4-Ring measurement system is the most accurate method measuring conductivity available today. HI 8820 is a professional instrument designed to satisfy the needs of the sophisticated user, while maintaining Hanna's user-friendliness. The advanced conductivity probe does not require changing or re-calibration when switching from one range to another. HI 8820 is ideally suited for use in the areas of quality control and general laboratory use.
Operation is simple, and can even be performed by non-technical personnel.
The user can adjust the TDS factor in addition to the temperature coefficient. The large Liquid Crystal Display will simultaneously show temperature and conductivity. HI 9032 is the most technologically advanced bench-top conductivity meter on the market. In addition to the wide range of conductivity, this meter will measure fertilizer concentration, sea water percentage, Total Dissolved Solids concentration and temperature. HI 9032 is essentially 5 meters in 1.
