The HI-8033 is a handheld conductivity meter with the ability to take measurements in three different ranges. The included HI-76301W probe utilises the four-ring potentiometric method which measures conductivity with the utmost accuracy and reliability. The four stainless steel rings are embedded in the resin shaft of the probe to create a smooth surface for fast and easy cleaning. To improve accuracy in measurements, temperature compensation can be achieved with a knob on the front panel of the meter. The dial on the front of the HI-8033 easily indicates which range you are working in.
