    This series of test chambers is manufactured referring to GB10592-89 which stipulates the technical standards about the high & low temperature test chambers, and is applicable to tests in both low and high temperature according to GB/T2423.1-2, which standardize the way to test electrician or electronic products in both situations.

    This type of test chambers adopts the balanced thermo-control measure for test chambers, which is the most advanced technology up to now. Therefore the precise testing temperature in the transition from high to low temperatures or in the inverse direction can be reached automatically at customer’s pleasure.

    All the main components of this type of chambers are imported from overseas. The product has excellent performance, appealing appearance and high reliability, which guarantee it an ideal choice for test in labs.

Performances:

  • The product can meet various needs of users due to its large scale in temperature control.
  • The special thermo-control measure can provide ideal temperature condition. It also has the heating capability in a stable and balanced way and can adjust temperatures precisely and stably.
  • The KP1000 programme-controlling meter are used in the temperature control system which are introduced from Japanese companies FUJI, SENNO, etc.
  • This type of product has the function of choosing cooling loop automatically in accordance with preset temperature and is very easy to handle as well.
  • The sequence controlling panel used in the test chamber simplifies the job of temperature setting. A more precise testing condition can be created if we adjust the variance setting to zero.
  • The watching widow installed at the gate of the chamber makes it convenient to inspect the samples in it.
  • The chamber can run in high temperature, and is able to cool down itself quickly even the temperature inside reaches 130 .
  • The condenser of the cooling system adopts the air swept type, and the close circuit compressors are all from overseas.
