HANNA HI 993310 Manual

Update: 29 September, 2023

The HI 993310 is a portable water conductivity and soil activity meter that allows for quick and simple measurements of soil activity, conductivity of irrigation water, nutritive solutions, and saturated soil-paste. The meter comes with two probes: HI 76305 with a stainless steel conic tip for direct soil measurements, and HI 76304 for fertilizer enriched solutions. The meter has two LED indicators for displaying the tested parameter and an alarm LED that lights up if the soil is too dry or lacking nutrients. Calibration for conductivity measurements can be done using a knob on the front of the meter, and the soil activity measurements are calibrated through conductivity calibration. Temperature affects conductivity measurements, while soil activity depends on soil texture and hydric property; both probes include a temperature sensor for automatic temperature compensation.
