TPDR-10/TPDR-16/TPDR-28

It is used to determine the resistance of concrete specimens to repeated cycles of freezing and thawing in the laboratory by rapid freezing and thawing in water method.

STANDARD

· ASTM C666

FEATURES
◎ The compressor, heating device and power control part are all imported parts with high quality and high performance.
◎ When running at full load, the temperature difference at each point in the freeze-thaw cabinet does not exceed ±2℃.
◎ Display data curves in real time and automatically store test data.
◎ It has an automatic recovery function when the test is accidentally interrupted.
◎ Easy installation, small footprint, low noise
