Stamdard temperature humidity environmental test chamber with ce certificate, which simulate the effects that a range of temperature and humidity conditions have on a product or material, such as telecommunications equipments, photo solar panels that are ecposed to outdoor temperature humidity environment.
They have application in industries as disparate as food science, semiconductors and military quality assurace. A good temperature humidity machine is essential for evaluating potential success, failure of a product in the field. Climate test chambers come in a variety of sizes, from a small box that fits on the bench top to a room size chamber for large objects, for testing large batches of product simultaneously. Temperature ranges from standard -70 degree to 150 degree(can custom -73 degree to 180 degree) and relative humidity ranges between 20% and 98% are available. A climate test chamber can be used when constant climate conditions by temperature, both temperature and humidity need for product physical tests.

1) The system allows users to set max. 120 groups of patern/programs(PTN)x1200 sections(SETP), each program can be arbitrarily devided into any number of segments.
2) Each running program can be operated for 9,999 times, or repeated for unlimited times of cycle, meanwhile the running program can be devided 5 groups to execute additional parts of the cycle.
3) Adopts intelligent type micro-competer PID + SSR/SCR, be able to sync output in positive & reverse direction automatically, controlling precision is accurate & stable, containing advanced slope controlling logic, fully meet customers' testing purposes.
4) When setting of temperature, humidity and number of cycles and so on is done, graph of relevant settings can be generated immediately, and these graphs can be obtained at the same time while programs are running.
5) Containing 15 fully-functional system inspection devices, so as to ensure the operational safety of the equipment, when there is trouble detected, controlling power will be cut off, meanwhile, trouble occurrence time, name of the trouble item and solutions will be indicated on screen automatically.
