Benchtop temperature and climatic test chambers simulates your samples testing work with temperature range -70C +150C and humidity range 30%~95% for product performance evaluation purpose ! The benchtop test chamber include one powerful France Tecumseh compressor, and two-kilowatt heating device that has optimum cooling and heating performance. The testing room 300*300*250mm (W*D*H) of Wewon benchtop environmental chamber keeps the flexibility to accommodate both mini type and large size test samples.

According with the requirements of today’s science laboratory environments, The structure of Wewon bench-top type temperature & humidity chamber incorporates a compact exterior that maximizes the inside testing room. If continuous testing is carried out, repeated heating and cooling test will reduce the performance of benchtop temperature humidity chamber. Therefore, We recommend that diversified sample tests should be given priority in the testing period. During the operation of the climate test chamber, Please inject distilled water into the water tank. Because tap water will shorten the service life of the heater.

The optimum quantity of refrigerant is controlled by adjusting the electronic expansion valve. Adjust the wasted calorific value and refrigerating capacity to make sure that the Wewon benchtop temperature humidity test chamber will save energy. For humidity testing needs of customers, the benchtop temp humidity test chamber can achieve automatic water supply function. When the pressure of the purified water inlet is more than 3kg/cm2, the pressure regulating valve shall be installed. No relief valve is required when the pressure at the purified water inlet is below 3kg/cm2. If automatic water supply is required, it needs to be specified when ordering to us.
