Hanna Instruments Soil Test™ Direct Soil EC Tester

Direct soil conductivity tester for measuring salinity and nutrient levels without sample preparation.

Measures electrical conductivity directly in soil; no extraction needed
Indicates soil salinity and overall nutrient levels
Fast digital readings for immediate results
Portable, durable design for field and classroom use
Simplifies soil testing for student investigations
Aligned to soil systems and environmental interactions (NGSS: MS-ESS2, HS-ESS2)

The Soil Test™ Direct Soil EC Tester allows students to measure electrical conductivity directly in soil, eliminating the need for time consuming sample preparation. By providing immediate digital readings, the tester enables quick assessment of soil salinity and overall nutrient content. This makes it ideal for investigations into soil quality, plant growth conditions, and the impact of environmental factors such as irrigation and fertilizer use. Its portable design supports both classroom experiments and field studies, helping students explore the connections between soil chemistry and ecosystem health in alignment with NGSS standards.
