Most enquiries start in the same place: a test procedure with a temperature range and a specimen that has to fit somewhere. This tool turns those numbers into a series and a model drawn from the chambers TestEQ publishes, so the conversation can start from a concrete configuration instead of a blank sheet.
Chamber selection tool
How to use it
- Pick the test type. Temperature-humidity, rapid temperature change, ESS, thermal shock, altitude, thermal vacuum, walk-in and benchtop chambers are covered.
- Set the temperature range you need at the specimen, and the internal space the specimen has to occupy.
- Enter the load — specimen mass and, if the item is powered during the test, its heat dissipation.
- Read the result. It names a model and repeats the figures that come with it, with a link to the full specification page.
What the result means
The tool filters the published model range: a model is only offered when its published temperature range covers your range and its interior dimensions enclose your working space on every axis. Nothing outside the published tables is generated.
Two limits are worth stating plainly:
- It does not calculate refrigeration performance for a live load. A powered specimen that dissipates heat changes the sizing, and that check belongs to the engineering review .
- It does not confirm that a specific standard can be met. Standard compliance depends on the profile, the tolerances and the measurement points, and is confirmed during the same review.
If no published model covers the range, the tool says so instead of stretching a figure.
Next step
Take the result to the engineering review together with the test standard and the site power supply, and you will get a configuration with the performance figures attached.
