平面电极土壤 pH 计
Pastes, slurries, potting media and small cores are awkward to immerse, so a flat electrode makes more sense. Press it against the sample and read 0–14 pH at 0.01 resolution, with ±0.05–0.1 accuracy. Two- or three-point buffer calibration and ATC from 0 to 50 °C keep screening consistent; 500 readings fit in memory. Pointed tips are available.
