| 摘要 |
A measuring device for determining the hardening duration of binding materials and core compounds comprises a container (3) for the test specimen (4) placed inside a heating furnace (2), a pick-up (7) of electrophysical parameters which is in contact with the test specimen (4) and a unit (9) for measuring the temperature of the heating furnace which is connected to the latter. The device is provided with a switch on/switch off unit (10) and comprises further a unit (11) for measuring the electrophysical parameters of the test specimen, that unit containing, connected to each other, a value indicator (12) for the electrophysical parameters and an electrophysical parameter converter (13) electrically connected to the electrophysical parameter pick-up (7) to the switch on/switch off unit (10) and to the unit (9) for measuring the temperature of the heating furnace. |
