Apparecchio di penetrazione a stantuffo

Plunger Penetration Apparatus is a professional penetration device designed to quickly, reliably, and repeatably determine the consistence (workability) of fresh wall mortars. The rigid chassis and low-friction vertical guide ensure that the plunger advances along a perfectly vertical path with free movement, minimizing operator-induced errors and providing consistent measurements across batches. A high-contrast, millimeter-scaled gauge allows precise reading of penetration depth, while the locking/reset mechanism enables rapid initial positioning before each test. The plunger, manufactured with the geometry and mass specified in standards and featuring a smooth, processed surface, performs measurements without disturbing the specimen. The sturdy sample container and alignment supports keep the sample centered, ensuring uniform contact. Corrosion-resistant coatings, smooth lines, and easily detachable plunger–cup components reduce cleaning time. Adjustable leveling feet and a wide base minimize the effect of vibrations on the measurement. Optional accessories include a sample preparation funnel, surface leveling blade, timer, and environmental monitoring module for temperature and humidity, enabling easy integration of consistency measurements into quality management procedures. The apparatus architecture is developed to meet the requirements for determining fresh mortar consistence via plunger penetration, providing dimensional accuracy, vertical guidance, and reading precision in compliance with EN 1015-4. Plunger Penetration Apparatus delivers standard-compliant, comparable, and reportable results for production quality control, acceptance testing, and admixture or mix comparisons.
