The Labtest Digital CBR Testing Machine is designed for performing laboratory evaluation of the California Bearing Ratio value of highway sub bases and subgrade and for the determination of strength of cohesive materials which have maximum particle sizes less than 19 mm (3/4”). The machine is designed to be mounted on a suitable bench and comprises of a robust and compact two column frame with adjustable upper cross beam. The frame is 50 kN capacity. Three test speeds are provided 1.25 mm/min, 1.50 mm/min & 2.5 mm/min tests. This main feature allows the user to perform tests. Laboratory California Bearing Ratio Apparatus with software & PC interface.

Salient Features:

1. No need of separate observation on dial gauge and proving ring.
2. Facility to readout rate of loading in mm/minute.
3. Tare system to nullify initial load
4. The digital lcd display will retain the peak value until it is cleared.
5. Flow value and load on a single screen.
6. Flow value with a least count of 0.01 mm with accuracy of 1%.
7. Load value with a least count of 0.1 kg / 0.001 kn with accuracy of 1%.
8. Back light facility to observe the readings even in the dark.
9. Two line readout showing load, flow, and speed.
10. Software interface to PC and plot live graph.
