Direct Soil Measurement pH Portable Meter
The HI99121 is the perfect portable pH meter for soil testing. With the HI99121 and HI1292D direct soil pre-amplified pH and temperature probe, users can test both the pH of soil directly or after preparation of a soil slurry with deionized water. The HI1292D features a conical, rugged tip that can be directly inserted into moist or soft soil. For harder soils, the kit includes a plastic auger to perforate the ground.
