Choosing a Weiss Chamber

Climate & Temperature Chambers by Weiss Technik


We often get enquiries from potential Customers, who know they need a test chamber but don’t know where to start to decide what type of chamber they want. In ‘Choosing a Weiss Chamber’, we show you the main considerations and where they lead you in the Weiss range. This range is vast, so we have narrowed it down and will concentrated on the most popular parts of the range.


Amongst the parts excluded are ovens that have no cooling, vacuum ovens, thermal shock chambers, corrosion, emission, light testing, splash, stability, extra-large, PV testing and vibration chambers.

Types of Chambers

The most popular chambers are the LabEvent, TempEvent and ClimeEvent chambers. They have a series of numbers in their name which mean the following:

Test space volume/lowest temp/cooling rate, e.g. ClimeEvent C 180/70/5 is a chamber with humidity, 180 litres test space cools to -70C and at 5K/min.

The Questions

And so to the basic questions which would mostly apply to all manufacturers:

  1. Is humidity control required?
  2. What low temperature is required? ≤ 0, ≤-40 or ≤-70°C?
  3. What is the highest temperature required?
  4. What test space dimensions are required?
  5. What is the maximum mass of samples?
  6. What is the sample material?
  7. What is the samples dissipated heat, if any?
  8. What temperature ramps will be required; from what temps to what temps?
  9. What ramp rates will be required with this maximum mass and dissipation?
  10. Do the ramps need to be linear? N.B. linear ramps require more power and so more cost.
  11. Will the test samples emit any corrosive or combustible gases/liquids? Do the test samples have explosive potential? (ATEX considerations)
  12. Will any option be required e.g. extra shelves, wheels, door with window, extra ports, low dew points?

More Information

For safety reasons if combustion or explosion is possible a detailed checklist is filled out and submitted to Weiss for a detailed quote.
