Hanna HI99121 | Direct Soil pH & Temperature Meter with Measurement Kit

Soil pH affects nutrient availability, but sending every sample for lab preparation isn't always practical when growers need quick decisions across several plots. The Hanna HI99121 Direct Soil pH Meter provides a simpler field solution for measuring pH directly in suitable soil or in a prepared soil slurry.

Its HI12923 glass-body electrode has a rugged conical sensing tip for soil penetration, a refillable reference system and an integrated temperature sensor. The meter displays pH and temperature together, provides automatic temperature compensation and supports automatic one- or two-point calibration. A ground auger and HI7051 soil preparation solution are included for soils where direct insertion could damage the glass sensor or give poor contact. Compared with the more advanced HI98168, HI99121 is aimed at straightforward routine field measurement.

The HI99121 is particularly practical for Pakistan's farmers, horticulture businesses, nurseries, greenhouse operators and agricultural consultants who need quick soil pH information before fertilizer or crop-management decisions. Its direct-soil probe and preparation accessories support field use without a full laboratory setup. Kamadi Pakistan offers the Hanna HI99121 for convenient agricultural soil pH testing.

Direct Soil Tester Selection Guide

Choose HI99121 for routine direct soil pH testing with simple operation. Select HI98168 when you additionally need 0.001 pH resolution, five-point calibration, logging and GLP.
