Precise pH Measurement in Pastes, Gels, and Soft Solids: Semisolid pH Meter ST101

Accurately measure pH in challenging non-liquid matrices with the Semisolid pH Meter ST101—a specialized handheld instrument engineered for foods, cosmetics, pharmaceuticals, soils, and biological samples that are too thick, viscous, or heterogeneous for standard pH electrodes. Featuring a flat-tip, spear-point ISFET or ruggedized glass electrode, the ST101 delivers reliable readings directly in creams, gels, cheese, meat, dough, mud, and more—without dilution or sample preparation.

Engineered for Direct Surface and Penetration Testing

The ST101 Semisolid pH Meter combines a shatter-resistant, flat-surface or conical-tip sensor with a compact, ergonomic body for easy insertion and surface contact. Its ISFET-based (or reinforced glass) probe resists breakage, clogging, and dehydration—critical for repeated use in abrasive or dry materials. The meter provides ±0.02 pH accuracy, automatic temperature compensation (ATC), and fast stabilization (<15 seconds) even in low-moisture samples.

Specialized Electrode for Semisolids – Flat or spear-tip design for direct contact with pastes, gels, powders, and soft solids.
No Sample Dilution Required – Measure true pH without altering sample composition.
High Accuracy: ±0.02 pH | Resolution: 0.01 pH – Suitable for QC and R&D in regulated industries.
IP65 Splash-Resistant Housing – Protected against cleaning sprays and moisture in production environments.
Automatic Calibration (1–2 Point) – Quick setup with standard buffers; ideal for routine checks.
Compact with Protective Cap & Storage Case – Includes electrode storage vial and calibration solutions.

Trusted Across Food, Pharma, and Environmental Applications

From verifying the pH of yogurt, mayonnaise, or topical creams to testing soil slurries, meat freshness, or cosmetic formulations, the ST101 eliminates guesswork and ensures product safety, stability, and compliance. Its ability to measure undiluted samples preserves accuracy—since dilution can shift pH values and misrepresent real-world conditions.

Whether you’re in a cheese plant, a dermatology lab, or a soil science field station, the Semisolid pH Meter ST101 delivers the right tool for materials that don’t pour—but still need precise pH control.

Measure as-is. Trust your results. No compromises.
