Perfect environment simulation for temperature test and climate test


The climatic test chamber CTC and temperature test chamber TTC are, with a rated power of 7000 Watts, extremely powerful due to the optimally coordinated heating and cooling technology. Largest possible energy efficiency and reduction in noise had been two criteria for the Memmert engineers to fulfill.

With a chamber volume of 256 litres, they provide plenty of space to offer, yet have a low floor space requirement because of their narrow and compact construction. In addition, the appliances can be conveniently moved on castors through any standard laboratory doors.

Stainless steel - a climatic test chamber (almost) for ever


60 years of permanent development work, as well as numerous amounts of feedback from practical experience, are embodied in each of our appliances:

  • The modular manufacturing concept in accordance with the principle of equal parts enables a highly varied and cost-effective production
  • Almost exclusive use of high-quality, corrosion-resistant and easily cleanable stainless steel for the working chamber and housing
  • Heating concept adapted to the specific product for a precise and homogenous temperature control independent of chamber volume and load
  • A wide range of options for programming and documentation using interfaces, Celsius software, integrated log memory and chip cards (features dependent on the controller class)
  • Three-year guarantee for appliances except wear and tear parts
  • The temperature values of all climatic test chambers are measured according to DIN 12880:2007-05 and DIN IEC 60068-3-5
