A temperature and humidity chamber (also referred to as a humidity chamber, climate chamber, or stability chamber) is a controlled-environment test enclosure that independently regulates both temperature and relative humidity. It is used to simulate real-world environmental conditions — from cold storage to tropical heat and humidity — to evaluate how products perform and degrade over time. Temperature humidity chambers are a cornerstone of accelerated life testing (ALT) and HALT/HASS programmes. They are commonly used to meet requirements under IEC 60068-2, MIL-STD-810, JEDEC JESD22, and ICH Q1A pharmaceutical stability guidelines.

Frequently Asked Questions

What is the typical humidity stability?

Our chambers maintain a high level of stability, typically within ±2% RH to ±3% RH during steady-state conditions.

Can I use the chamber for ICH stability studies?

Yes. Our humidity chambers are widely used for pharmaceutical stability testing according to ICH guidelines.

Does it require a continuous water supply?

A demineralized water supply is recommended. Most models include an internal tank or can be connected to an external source.

What is the largest chamber volume available?

We provide standard volumes up to 2000L and offer walk-in climatic rooms for larger requirements.

Do you provide DQ/IQ/OQ/PQ documentation?

Yes. We offer comprehensive validation documentation packages for laboratory and pharmaceutical customers.

What is a temperature and humidity chamber used for?

A temperature and humidity chamber simulates real-world environmental conditions — from freezing cold storage to tropical heat and high humidity — to test how products perform and degrade over time. It is widely used for accelerated life testing, pharma stability studies, automotive component validation, and electronics reliability testing.

What is the difference between a hot chamber and a cold chamber?

A hot chamber tests products under elevated temperatures to evaluate heat resistance, material degradation, and performance at high thermal stress. A cold chamber tests under sub-zero conditions to assess low-temperature performance, brittleness, and cold-start reliability. A temperature and humidity chamber combines both hot and cold testing in a single unit with added humidity control.

What temperature range does Indeecon's temperature and humidity chamber cover?

Indeecon's standard temperature and humidity chamber covers -40°C to +180°C. The ultra-low option extends this to -70°C to +180°C, making it suitable for cold chamber applications in aerospace, EV battery testing, and pharmaceutical cold-chain validation.

Can this chamber be used as a cold chamber for EV battery testing?

Yes. The ultra-low temperature option (-70°C to +180°C) makes it suitable for EV battery thermal performance testing, cold-start simulation, and thermal cycling as per IEC 60068 and MIL-STD-810 standards. The chamber can also be configured as a dedicated cold chamber for specific low-temperature applications.

Can the hot chamber function be used independently without humidity control?

Yes. Indeecon's temperature and humidity chamber can operate in dry heat mode as a standalone hot chamber — without activating the humidity system. This is useful for dry heat testing per IEC 60068-2-2 and thermal ageing studies where humidity is not a test variable.

What is the difference between a temperature and humidity chamber and a thermal shock chamber?

A temperature and humidity chamber gradually ramps between hot and cold conditions while controlling humidity — ideal for long-term ageing and stability studies. A thermal shock chamber rapidly transfers products between extreme temperature zones in under 30 seconds — designed for mechanical stress and material failure testing. Both serve different testing standards and use cases.
