Digital machine for testing compressive forces with single gauge also availablethe digital compression testing machine is crafted to meet the necessity of economic and, A simple reliable means for evaluating concrete quality for its compressive strength. The digital indicator incorporates a 4, Digits display calibrated in kilo newton kn and preset to maximum load capacity fitted with micro switches to switch, Off the motor when the load approaches the maximum capacity of the gauge, Avoiding any over loading. Relays are incorporated in order to secure the motor does not restart independently after a power breakdown.
