Ductilometer 1000 mm digital for the determination of load ductility and elastic reset of bitumen. Stainless steel casing with isolated water bath with cover and glass window as well as a stepper motor providing a variable speed range 1 to 50 mm/min. with digital displacement measuring system. Up to 4 samples can be tested simultaneously. Fully computercontrolled version with Windows software. One measuring place is equipped with an electronic load transducer 500 N, resolution 0,1 N (100 N, resolution 0,01 N as an option). Three more load transducers 20-2357 can be connected. The complete test is controlled by the software included with on-line graphics and data base as well as evaluation of test with calculation of planimetrie. Special test sequences can be programmed by the user himself. The water bath temperature can be recorded continously by use of temperature sensors 20-2359, available on option. For operation a computer with Windows has to be provided.The bath temperature can be controlled by a ductilometer Bath Heating Thermostat (20-2370), if required with additional cooling unit (20- 2375) or an external cooling/heating unit. (Test moulds, bath heating attachment and computer are not included).
