Description
CONTROLS Proctor/CBR universal compactor automatically performs programmable and uniform compaction cycles in full conformance to all standards. Users can automatically set dropping height with high precision. This eliminates inconsistencies in test data generated by manual adjustments and guarantees accurate and reliable results every time.
Multi-standards
Universal and fully automatic universal compactor matching all Standards AS, EN, ASTM, AASHTO, AS, BS, NF, AS, and others, including central stroke.
Superior accuracy
The Proctor/CBR universal compactor continuously measures and adjusts the dropping height at each stroke during compaction. Equipped with a robust kit rammer, high precision compaction is maintained throughout the whole compacting path.
Fully automatic and versatile
Dropping height is set from the digital display without the need for any manual adjustments. The mould fixing system uses a quick release clamping mechanism compatible with Geo-Con and CONTROLS CBR/Proctor moulds.
Optimal user interface
The user-friendly interface boasts a high-resolution colour graphical display 128 by 80 pixels as well as a membrane keyboard. You can access pre-stored test procedures in multiple languages plus tailor test methods according to your needs.
Ergonomic and safe
This fully CE compliant machine features a double door system with see-through panels that provides a clear view and easy access to the testing chamber during compaction. If doors accidentally open, a safety switch will automatically stop the machine plus a STOP button is also close at hand in case of emergency.
Total functionality and easy operation
The machine is supplied with a universal impact rammer (50 mm and 2”dia.) that can be swapped in a few seconds. Adjusting the supplied weight is equally easy and can be done in one single operation.
A noise reduction steel cabinet with double top-and-front opening system and lined internally with soundproofing material is available on request.
