The Hanna Instruments-99121 kit has been designed to measure the pH in soil. Every item in this kit has been made to facilitate measurements in the field without compromising accuracy.

With the Hanna Instruments-99121N and Hanna Instruments-1292D direct soil pre-amplified pH and temperature probe, users can test both the pH of soil directly or after preparation of a diluted sample. The Hanna Instruments-1292D features a conical, rugged tip that can be directly inserted in moist or soft soil. For harder soils, the kit includes a plastic auger to perforate the ground.
