Scratch Hardness Apparatus
Model: AggrenoX 32
Manufacturer & Exporter: SCIENTICO
Standard: ASTM C851

Product Overview:
The AggrenoX 32 Scratch Hardness Apparatus is a precision-engineered device used to determine the quantity of soft particles in coarse aggregates based on scratch hardness. This test is essential for assessing aggregate quality and ensuring the durability of concrete and pavement structures. Fully compliant with ASTM C851, this apparatus is a standard tool in aggregate testing laboratories.

It features a 1.6 mm (0.0125") diameter brass rod with a rounded tip mounted in a precision plunger mechanism. The plunger, with a total weight of 2 ±0.1 lbs (8.9 ±0.4 N), is designed to move freely within its support stand, ensuring consistent and repeatable testing. The apparatus comes with a replacement brass rod, ensuring continued usability and accuracy.
