Freeze-Thaw Test Chambers/Cabinets
Product Code: TPDR_Series
Categories:
Application
This method is used to determine the resistance of concrete specimens to repeated freezing and thawing cycles in the laboratory by means of rapid freezing and thawing in water.
Standard
- EN 12390-9
- ASTM C666
- GOST 10060-12
Features
- The compressor, heating unit, and power control unit consist of high-quality and high-performance parts.
- When operating at full load, the temperature difference at any point in the freeze-thaw chamber does not exceed ±2℃.
- Displays data curves in real time and automatically records test data.
- It has an automatic recovery function in case of test interruption.
- Easy installation, small footprint, low noise
