Professional Vineyard Soil pH Tool

Field-grade analog pH and moisture tester developed for commercial viticulture and intensive horticulture. Dimensions: 155 × 35 × 25 mm; weight: 85 g. Core sensor: solid stainless steel probe with passive electrochemical interface; body: matte-black UV-resistant ABS with IP65-level probe seal. Measures pH 3.5–8.0 (±0.2) and relative moisture on single dial. Fully waterproof at probe zone; tested for 500+ insertions in gravelly vineyard soils without loss of sensitivity. Compatible with all UK soil types — including acidic heathland sands, neutral loams, and alkaline chalk downs — and validated against laboratory composite samples from ADAS and FERA reference labs. Unlike consumer-grade pens, this tool uses a linear response curve mapped to British soil buffering capacity, reducing overestimation of acidity in high-cation-exchange soils. Moisture scale reflects dielectric shift rather than simple resistance — improving reliability in saline or manure-amended plots. Endorsed by the English Wine Producers’ Association for routine block-level monitoring and included in several DEFRA-funded soil health pilot schemes across Sussex, Kent, and Hampshire vineyards.
