The HI 9033 is a rugged meter designed to hold up under extended use in wet, humid, dusty and muddy conditions. It utilizes a single probe, and performs conductivity readings in all four ranges. It can measure samples from deionized water to brine without having to switch or recalibrate the probe.

The HI 9033 performs measurements with ATC (automatic temperature compensation) which adjusts for the effects of temperature on the probe. It also features BEPS (Battery Error Prevention System) technology that alerts the user when low batteries could affect the readings.
