Freezing and Thawing Testing Machine Manufacturer

TBTTDR-16 is designed to evaluate the frost resistance and durability of concrete specimens under rapid water-immersion freezing and thawing cycles. By subjecting specimens to automated alternating periods of freezing and thawing in water, the system simulates severe winter weathering conditions in an accelerated laboratory environment. Equipped with an advanced control system, TBTTDR-16 ensures precise temperature monitoring and compliant cycle timing, providing reliable data for concrete service-life prediction.

ASTM C666

1. Compressor, heating part, power control part are imported parts, high quality, high performance;

2. MAX-MIN temperature of each point is not more than ± 2℃ in the cabinet when full load running;

3. Automatic control of instrument, real-time dynamic display of data curve, automatic storage of test data, and automatic recovery of test when unexpected break;

4. Convenient installation, small occupation and low noise.
