The HI99121 is the perfect portable  Direct Soil Measurement pH Meter. With the HI99121 and 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 pH-electrode 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.

The HI99121 meter features a large multi level LCD screen which displays both pH and temperature readings simultaneously with 0.01 pH resolution and an accuracy of ±0.05 pH. 

The LCD screen also has indicators for calibration status and stability, as well as on-screen tutorial messages. 

The HI99121 has many advanced features that are found in more expensive portable instrumentation including automatic calibration, buffer recognition,and temperature compensation. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. 

The supplied pH-electrode is a glass body, amplified pH electrode with a built-in temperature sensor designed specifically for measuring the pH in soils.

With the HI 99121 and HI 12923 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 HI 12923 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.

Order Information: HI99121 is supplied with HI 12923 pH electrode, HI 721319 soil auger, HI 7051M soil preparation solution, 100 mL plastic beaker, batteries, instructions and a hard carrying case.
