Rapid Freeze Thaw Chamber

Model: HNJ-DR

Standards: ASTM/C666


The rapid freeze thaw chamber is used to test the Antifreeze performance of concrete, the antifreeze means the concrete specimen Anti-destructive ability subject to repeated freeze and thaw activity. It’s kind of very important concrete durability test equipment. 


Features

●Fully Automatic test, when set times reached will stop automatically

●Human friendly design, LCD real-time display temperature variation conditional curve, 

●Built-in printer for real time data print

●Solid-state relay control, no electric magnetic filed interference, guarantee long-term stable operation

●Upper computer software can batch import history data to computer, also can real time control the test and

●Print conditional curve, thus for easier analysis.
