Hanna Instruments HI993310 Dual Soil / liquid EC meter



  • Supplied with two probes
  • Automatic Temperature Compensation
  • BEPS (Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings

HI 993310 is an instrument that has been designed to address the need for fast and accurate conductivity measurements in soil and liquids. It is supplied with two probes: HI 76305 with stainless steel, conical tip for direct soil measurement and HI 76304 for fertilizer enriched solutions.

HI 993310 measures the soil conductivity in EC (mS/cm) as well as salt activity (g/L). The different scales can be selected through two keys on the front panel and two separate LEDs indicate which parameter is being tested. In addition, HI 993310 is equipped with an alarm LED that illuminates if the soil is too dry or nutritive substances such as potassium or nitrogen are lacking. Demineralized water can be added to the soil prior to proceeding with further tests.

Direct soil measurement is facilitated by the stainless steel HI 76305 probe. Once inserted into the ground, the user simply waits until the meter displays the value read by the auger-like probe.
