Thermal Shock Test Chamber (Three Zone)

Bellue’s three-zone thermal shock chamber keeps the specimen in a stationary test zone and switches hot and cold air from separate storage zones. Confirm the temperature profile, specimen load, exposure time, and recovery criteria for the selected configuration.

Operation precautions

Review the operating manual and installation requirements for the delivered configuration before use. Confirm specimen suitability, cable routing, utilities, and authorized operating conditions for the approved test program.

The thermal shock test machine body cannot press the power line, nor can it be stepped on the power line;
Do not spray or rinse the equipment directly with water, and do not place the equipment in a damp, easily splashed place, so as not to affect the electrical insulation performance of the equipment;
It is strictly forbidden to use it when the power line is damaged or the plug is worn out, because the wear or damage of the power line may cause an electric shock to the operator, and must be replaced by a professional electrician according to the provisions of the thermal shock test chamber;
In order to ensure the safety of operators, do not place electrical sockets, stabilized power supplies and other electrical appliances on the table of the equipment, and it is also prohibited to use electrical appliances inside the equipment to avoid electromagnetic interference and malfunction;
It is strictly forbidden to put inflammable and explosive dangerous goods, as well as strong corrosive acids and alkalis;
It is strictly forbidden to place or use gasoline and other flammable materials near the thermal shock test equipment to avoid fire.
