The HI98331 Soil Test™ is a pocket tester specifically designed to directly measure soil conductivity (EC) and temperature. With a compact size, single button operation, and automatic calibration, Soil Test is an excellent choice for taking direct conductivity measurements in soil.

• No need for soil slurries with the steel penetration electrode. 
• Integrated temperature sensor for automatic temperature compensation. 
• Great for environmental and agricultural testing.
