Three Zone Thermal Shock Test chamber Thermal Shock Test Chamber Liquid Thermal Shock Test Chamber Programmable Three Zones Thermal Shock Test Chamber is applied to aviation, military, ships, electrical, electronics, instruments and meters; medical equipment; civilian nuclear energy; colleges and universities; research laboratories; commodity inspection, arbitration, and technical supervision departments; building materials ceramic; petroleum and chemical products, For high and low temperature impact test. Three Zone models have higher performance, three-zone capability, and larger heating/cooling performance that fully benefits from Eco-mode innovations.Equipped with original Japan made true-color touch screen controller with software of both English and Chinese version.It consists of 3 Zones:1,High temperature Zone;2,Low temperature Zone;3,Testing Zone.Adopts unique thermal-break-structure class heating & cooling storage method,then leads hot or cold air to testing zone for thermal shock tests.It can be adjusted shock temperature by switching the hot and cold air flow. High memory capacity,can set 120 programs and each program can be repeated for max 9999 times.Each step can be proceeded for max 999 hours and 59 minutes.It's able to communicated with computer via RS485 port,so as to control,edit and record 2 groups of dynamic nodes,easy to operate.Proceeding with thermal shock conditions,users can select either 2 Zone or 3 Zone test mode.All operations are controlled by PLC.Equipped with automatic circuit and alarm signal in case of emergency,machine will be shut down in urgent situation. New Eco-Mode is standard for all models. Eco-mode manages the pre-conditioning and modulates refrigeration systems to reduce energy usage. Savings of up to 50% over previous models is possible, or as much as $2,000 a year. Two Zone models are lower cost models with only two-zone capability, lower performance, and partial savings of Eco-modGrande�??s Exclusive Touch-Screen
