About Product :

We are foremost organization, actively occupied in providing a wide of California Bearing Ratio Test Apparatus that meet on customer’s demand. The California Bearing Ratio Test, (usually called CBR test) is an empirical penetration test for evaluation of mechanical strength of natural ground, subgrades and base courses beneath new carriageway construction. It is to determine the relative bearing ratio and expansion characteristics. It was developed by the California department of transportation before World War II.The test can be performed in the laboratory on prepared samples or in-situ on location. It is important to appreciate that this test, being of an empirical in nature, is valid only for the application for which it was developed i.e., the design of highway base thickness. The basic site test is performed by measuring the pressure required to penetrate soil or aggregate with a plunger of standard area. The measured pressure is then divided by the pressure required to achieve an equal penetration on a standard crushed rock material

Features:

• Precise design
• Durable 
• Calculates corrected CBR value at 2.5 and 5 mm the digital unit saves the load value at user defined displacement values such as 0.625, 1.25, 1.875, 2.5, 3.75, 5, 7.5,10, 12.5 mm
• The load corresponds to the displacements corrected respect to the linear region of the data has also saved
• The % CBR at 2.5 mm and % CBR at 5 mm is also automatically calculated and saved
• Can make test with displacement and limited load control.
• Real time display of test graph.
• CPU card with 32-bit arm RISC architecture.
• Permanent storage capacity up to 10000 test results.
• 4 analog channels, 2 channels are active for CBR.
• 1/256000 points resolution per channel.
• 10 data per second sample rate for each channel.
• Ethernet connecting for computer interface.
• 800x480 resolution 65535 color TFT-LCD industrial touchscreen.
• 4 main function keys.
• Multi-language support.
• 3 different unit system selection; kn, ton and lb
• Real-time clock and date
• Test result visualization and memory management interface.
• Remote connection through ethernet
• USB flash disc for importing test results and for firmware.
• USB printer support for inkjet and laser printers (ask for compatible models)
• Camera support for real-time video recording during test(ask for compatible models)
