FAQ:
1.What is the purpose of a Constant Temperature & Humidity Test
Chamber?
A Constant Temperature & Humidity Test Chamber is designed to
simulate specific environmental conditions, such as extreme
temperatures and humidity levels, to test the durability,
performance, and reliability of products, materials, or components.
It is widely used in industries like electronics, automotive,
aerospace, pharmaceuticals, and materials science for quality
control, research, and development.
2. What size options are available for the chamber?
Chambers come in various sizes, from compact benchtop models (e.g.,
50L) to large walk-in chambers (e.g., 1000L or more). The size you
choose depends on the dimensions of the samples or products you
need to test. Custom sizes may also be available upon request.
3. Can the chamber simulate rapid temperature and humidity changes?
Yes, many chambers are equipped with rapid temperature change (RTC) capabilities, allowing you to simulate sudden shifts in
environmental conditions. The rate of change (e.g., 5°C/min or
10°C/min) depends on the model and its cooling/heating system.
4. What is the lead time for delivery and installation?
Lead times vary depending on the manufacturer, model, and
customization requirements. Standard models may be available for
immediate delivery, while custom-built chambers could take several
weeks. Installation is typically handled by the supplier or a
certified technician.
