A penetrometer is a device used to measure the resistance of a material to penetration. It typically consists of a rod with a pointed tip that is pushed into the material at a controlled rate. The force required to achieve a specific depth of penetration, or the depth achieved with a specific force, is then measured. Penetrometers are employed in various fields, including soil mechanics, food science, and pharmaceuticals, to assess properties such as soil consistency, fruit firmness, and tablet hardness.

Different types of penetrometers exist, each adapted for specific applications. Cone penetrometers, often used in geotechnical engineering, utilize a cone-shaped tip to measure the bearing capacity and strength of soils. Needle penetrometers, with a finer tip, are common in food analysis for determining the ripeness of fruits or the consistency of jams and spreads. For pharmaceutical applications, specialized penetrometers measure the hardness of tablets, ensuring they meet quality control standards for disintegration and dissolution. The principle remains the same: quantifying resistance to penetration to infer material characteristics. The specific geometry of the tip and the force measurement mechanism are key differentiating factors among penetrometer types.
