Product Introduction

LR-BBR-PLUSBending beam flowmeterAccording to current regulations andSHRPMethod: Test the low-temperature bending creep stiffness of asphalt binder. Used to evaluate the low-temperature fracture characteristics of asphalt binder. The test results include low-temperature creep stiffnessS(t)And creep stiffness change ratem(t)Indicators. usePeltiertechnology/The compressor cools the temperature from room temperature to-40°CUsing magnetic stirring, the temperature control accuracy is within0.1°CInside, computers andBBRBetween adoptionRS-232/IP/USBCommunication, realizing theBBRControl, software can generate test reports.
