The HI98331 Soil Test™ is a pocket conductivity meter specifically designed to directly measure soil conductivity (EC) and temperature. The stainless steel electrode allows for direct penetration into soil and soil slurries.


There is a large LCD to simultaneously read conductivity and temperature values. The stainless steel penetration probe makes it the perfect field conductivity meter where you want to make a direct measurement without having to prepare a soil solution.

Meter is designed to be easily used with a single button and its automatic calibration function at 1.41 mS/cm.


The HI98331 meter includes: CR2032 battery (1 pc.) • Storage / Protection sleeve • Instruction manual • Quality Certificate


Calibration solution not included.

Recommended Calibration solution: Testagro EC141-60
