Freezing And Thawing Test Chambers in Air

The TESTMAK Freezing and Thawing Chambers are used for the determination of resistance to freezing and thawing by providing freezing / thawing in air. The chamber is equipped with a user defined program including 10 steps. Time can be adjusted to 999 minutes for each step of the program. The temperature range of the cabinet is -25°C to +30°C.
The temperature is controlled by a sensor which can be immersed either into the sample, into the water which the sample is placed into or, into the salty water solution placed on the sample before starting the test. The calibration of the sensor is carried out using the user friendly menu.
The cabinet provides maximum cooling 5°C/hour and maximum heating 10°C/hour. The distribution of temperature in the cabinet is performed using the integral fan.
Software for data transfer to a computer is supplied complete with the cabinet, and data can be monitored during the tests. Data can be converted to an excel report or to a graph. The condenser of the cabinet is fitted with an air cooled hermetic cooler. The gas used for the cooler does not include CFC’s.
