1、 Overview: An intelligent temperature and time controller is used to raise the temperature to the lower limit temperature through a stainless steel heating tube, and the temperature difference is kept constant. If the temperature is lower than the set value of the lower limit temperature, the device will heat up. When the control time is reached, the buzzer will sound, indicating the completion of the test

one、summary:Using an intelligent temperature and time controller, the temperature is raised to the lower limit temperature through a stainless steel heating tube, and the temperature difference remains constant. Heating is carried out below the set lower limit temperature. When the control time is reached, the buzzer sounds to indicate the completion of the test. The concrete alkali aggregate test box is suitable for temperature and time control during the expansion detection of sand and gravel aggregates. The concrete alkali aggregate test box is designed and manufactured in accordance with the requirements of the standard DL/T "Test Code for Sand and Stone Aggregates of Hydraulic Concrete".
