Precise Consistency Testing for Bitumen with the Semi-Automatic Bitumen Penetrometer DPS5

Ensure reliable quality control of asphalt binders and bituminous materials with the Semi-Automatic Bitumen Penetrometer DPS5—a robust, user-friendly instrument engineered to determine the penetration hardness of bitumen in accordance with ASTM D5, ISO 2137, IP 49, and EN 1426 standards. Widely used in road construction labs, asphalt plants, and materials testing facilities, the DPS5 measures how deeply a standardized needle penetrates a bitumen sample under controlled load, time, and temperature—providing critical data for grading and performance prediction.

Engineered for Reproducible, Standards-Compliant Testing

The DPS5 Semi-Automatic Bitumen Penetrometer features a precision-guided needle assembly (100 g total mass) that automatically releases and penetrates the bitumen sample for exactly 5 seconds, as required by international methods. The penetration depth is measured in 0.1 mm increments (e.g., 65 = 6.5 mm) and displayed via a high-resolution digital dial gauge. The unit includes a thermostatic water bath (optional or integrated) to maintain the sample at the standard test temperature of 25°C ±0.1°C, ensuring consistent, comparable results.

Compliant with ASTM D5 & EN 1426 – Validated for road bitumen, polymer-modified asphalt, and fluxed binders.
Automatic Needle Release Mechanism – Eliminates manual timing errors for improved repeatability.
Digital Readout (±0.1 mm Accuracy) – Clear, direct penetration value without parallax error.
Thermostatic Bath Compatibility – Maintains precise 25°C test conditions for method fidelity.
Includes Standard Needle & Sample Container – Meets dimensional and mass tolerances per ASTM/ISO.
Compact, Benchtop Design – Ideal for field labs, QC stations, and asphalt production facilities.

Trusted for Road Construction and Material Specification

Penetration grade (e.g., 40/60, 60/70, 80/100) directly influences bitumen selection for climate and traffic conditions. The DPS5 enables asphalt producers and civil engineers to verify binder consistency, detect contamination, or ensure compliance with national road authority specifications (e.g., AASHTO M 20, BS EN 12591).

Whether you’re testing incoming bitumen shipments or validating modified asphalt performance, the Semi-Automatic Bitumen Penetrometer DPS5 delivers dependable, standardized results that support durable, safe road infrastructure.
