DIGITAL PENETROMETER AZA0939

Description

Role of AZA0939 in Bitumen Consistency Evaluation

The penetration test is one of the most fundamental methods for grading and classifying bituminous binders. It measures the depth of penetration of a standard needle into a sample under controlled conditions:

• Standard load: 100 g

• Penetration time: 5 seconds (adjustable)

• Test temperature: Typically 25°C

Results are expressed in tenths of a millimeter (0.1 mm), directly indicating material hardness:

• Higher penetration values → Softer binders (suitable for cold climates)

• Lower penetration values → Harder binders (suitable for hot climates)

The AZA0939 performs this test with digital accuracy and automated control, ensuring consistent, reproducible, and operator-independent results that are essential for pavement design, quality control, and performance prediction.

Digital Precision and Automation for Superior Reliability

The AZA0939 distinguishes itself through its fully digital operation and automation, significantly reducing human error associated with manual penetrometers.

• High-resolution digital display provides direct readings with 0.01 mm resolution

• Electronic programmable timer automatically controls penetration duration

• Automatic needle release and locking system ensures precise start and stop of penetration

• Eliminates subjective interpretation and stopwatch dependency

• Ensures excellent repeatability and reproducibility, critical for audits and research applications

This automation makes the AZA0939 ideal for laboratories working under ISO, ASTM, and regulatory compliance environments.
