Temperature Cycling Test Chambers

A temperature cycling test chamber, also known as a thermal cycling chamber, is designed for rapid and uniform temperature changes, achieving rates of 5 – 25°C per minute or more. These chambers are ideal for applications that demand consistent, reproducible temperature shifts, testing a product’s durability against extreme temperature fluctuations. Unlike traditional temperature and humidity chambers, thermal cycling chambers induce fatigue failures similar to thermal shock testing, revealing potential weaknesses in a product.

Temperature Cycling Test Procedure

Thermal cycling tests involve multiple cycles of low-to-high temperature conditions. After completing the final cycle, operators perform a detailed inspection under 10x to 20x magnification, examining leads, casings, seals, and markings for damage. Any physical or electrical damage, such as cracks, wire breaks, or bond lifts, indicates test failure.

Choosing the Right Temperature Cycling Test Chamber

When selecting a temperature cycling chamber rental, consider:
✔ Temperature range
✔ Chamber dimensions
✔ Cycling rate (e.g., 25°C per minute or higher)
✔ Test standard compliance

Advanced chambers may feature internal specimen sensors for high-accuracy readings, high-speed controllers, and specialized heating/cooling liquids. Some temperature and humidity chambers can also be upgraded for thermal cycling by enhancing the unit’s processor.
