The HI-9033 is a rugged meter designed to withstand extended use in wet, humid, dusty or muddy conditions.With the ability to select from multiple conductivity ranges, it can measure samples from deionised water through to brine without having to switch or recalibrate the probe - ideal for use out in the field.Measurements are performed with automatic temperature compensation which adjusts for the effects of temperature on the probe.The instrument also features the Hanna battery error prevention system to help ensure it is in optimum working order before going out on location.
