Automatic Penetrometer:
PNR 500

Automatic sensor plunger ensures fast, accurate bitumen testing

The automatic penetrometer’s patented force-sensor plunger enables surface detection of highly viscous samples, even if they are submerged under water. This ensures reproducible penetration depth readings and eliminates the need for manual adjustment. A magnetic plunger and specialized bitumen needle simplify setup, while the Rapid Function accelerates workflows in busy QC environments. These features make the PNR 500 the ideal choice for reliable, automated bitumen testing in compliance with global standards. 

Quick, precise surface detection of conductive samples

For conductive, typically water-based samples, the PNR 500 automatic penetrometer offers surface recognition using an electrical conductive sensor. This smart detection function ensures precise positioning and minimizes user-dependent errors. The manual approach process is further simplified through a jog wheel, magnifier, and bright LED light for perfect visibility of the sample surface. Together, these tools guarantee accurate, reproducible penetration results even for challenging materials. 

One instrument for diverse materials meeting global standards

Rely on a single instrument that adapts to a wide range of materials – from bitumen and grease to waxes, butter, and pharmaceutical formulations while complying with all relevant international standards:

• Bitumen needles and plungers: ASTM D5, EN 1426
• Grease cones: ASTM D217, ASTM D1403, ISO 2137
• Pharma cones and needles: European Pharmacopoeia 2.9.9, USP 915, USP 1912
• Butter cones: AOCS Cc 16-60

Equip your automatic penetrometer with certified test kits to ensure traceable testing. Comprehensive IQ|OQ|PQ documentation supports quick qualification in regulated environments. 

Intelligent data management simplifies reporting across various industries

The PNR 500 automatic penetrometer streamlines data handling with integrated result evaluation and smart export functions. Test outcomes are converted into standardized values, such as NLGI class, EN bitumen, ¼-cone to solid-cone, or C-value for edible fats. Up to 200 test results can be stored and reviewed directly on the instrument. Results can then be exported via USB or LIMS connection for analysis in MS Excel or AP Connect – ensuring complete traceability and simplified reporting across departments.

Preset or custom programs for instant testing

Testing starts immediately with five preset programs for the most common applications or up to 15 individually customizable programs. Individual test sequences can be configured for maximum flexibility, while limit indicators trigger alarms when results deviate from preset ranges. Complement your setup with optional accessories such as circulator baths, and transfer dishes for temperature control, various sample containers, and a printer for direct documentation – ensuring full adaptability for any testing need.
