    The test chambers of this category are all in line with all indexes of GB10589-89 low-temperature technology testing, and can be tested in low temperatures according to GB/T2423.1-89, which standardizes the way to test electrician or electronic products under very low temperature.

    We adopt the balanced thermo-control measure for test chambers, which is the most advanced technology nowadays.

    The strengths of such chambers include novelty structure, appealing appearance, excellent performance, low noise, easy operation and high reliability, all of which make them an ideal choice as environmental test equipment in labs.

Characteristics of the performance:

  • These chambers can meet various needs of users due to its large scale in temperature control.
  • It adopts the unique balanced thermo-control system, which can offer ideal temperature condition as users desire.
  • Meters from Japanese companies (e.g. RKC and FUJI) are used in the thermo-control equipment.
  • This type of chamber has the function of setting low temperature(0-100) or high temperature(0 + 90)automatically with user’s choice.
  • The temperature in the test chamber is easy to set as a result of the touch switch. A more precise testing condition can be created if we adjust the variance to zero.
  • The watching widow installed at the gate of the chamber makes it convenient to inspect the samples in it.
  • The condenser of the cooling system adopts the air swept type, and the wholly-close compressors are imported from abroad.
