Rapid Temperature Change Test Chamber 5°C/min Linear Ramp -40°C to +150°C 225L Programmable

HongCe Rapid Temperature Change Test Chamber is a programmable environmental testing system designed for thermal cycling and temperature change testing of electronic, automotive, and industrial components. The chamber delivers a linear temperature change rate up to 5°C/min within a temperature range of -40°C to +150°C, allowing engineers to reproduce rapid thermal stress conditions in a controlled laboratory environment.

With a 225L test volume, SUS304 stainless steel interior, and a 7-inch color touch screen PLC controller, this chamber suits R&D verification, design qualification, and routine reliability screening applications that require repeatable heating and cooling ramps.

Many product failures occur not at a single extreme temperature but during temperature transitions. Thermal expansion and contraction, solder joint stress, and material fatigue are typically triggered when a product is cycled rapidly between hot and cold conditions.

The HongCe Rapid Temperature Change Test Chamber addresses this by combining a high-capacity refrigeration system, balanced heating elements, and a linear ramp control algorithm. The result is a chamber that maintains a defined temperature change rate across the full -40°C to +150°C range, giving test engineers a repeatable platform for thermal cycling, temperature shock simulation, and environmental stress screening.
