Hanna HI99121 | Direct Soil Measurement pH Portable Meter

The Hanna HI99121 is a portable pH meter designed for direct soil measurement and soil slurry testing. It is suitable for agriculture consultants, farms, nurseries, greenhouse operators, soil testing labs, and research departments that need reliable soil pH information.

The meter is supplied with the HI12923 direct soil pH probe, featuring a rugged conical tip, an open-junction design, and a glass body. A plastic auger is included to loosen harder soils before measurement, helping protect the pH glass from stones or nutrient crystals. The waterproof casing, dual-line display, automatic calibration, and temperature compensation make it useful for field testing.

For Pakistan’s farming and horticulture sectors, the HI99121 helps support fertilizer planning, soil correction, crop suitability checks, and nutrient management. Kamadi supplies Hanna soil pH meters for professional agriculture and laboratory use.
