Heat Cold Humidity Climate Chamber | Temperature & Humidity Testing

Heat, Cold and Humidity in One Climate Test

The heat cold humidity climate chambers can experience high temperatures, low temperatures, moisture, and changing environmental conditions during transportation, storage, and operation. A heat cold humidity climate chamber allows these conditions to be reproduced under controlled laboratory conditions.

Heat Testing: Expose products to elevated temperatures to evaluate heat resistance, aging, and performance stability.
Cold Testing: Simulate low-temperature environments for cold resistance, storage, and low-temperature reliability testing.
Humidity Testing: Control relative humidity from 20% to 98%RH for moisture resistance and environmental conditioning.
Climate Cycling: Combine temperature and humidity conditions into programmable test profiles for repeated environmental exposure.

Key Hardware & Operating Features of Heat Cold Humidity Climate Chamber

Frequently Asked Questions on Heat Cold Humidity Climate Chamber

Q1: How do I choose the right climate chamber size for my samples?

To ensure proper air circulation and accurate test results, your test samples should not occupy more than 1/3 of the internal chamber volume. Leave at least 5–10 cm of space between samples and the interior walls.

Q2: Does the heat cold humidity chamber require pure water for humidity testing?

Yes. To prevent scale buildup and protect the humidifier, purified or distilled water is recommended. The built-in water purification system helps condition the water supply for continuous operation.

Q3: Can I test powered/active electronic samples inside the chamber?

Yes. The chamber comes with a standard cable port (Ø 50mm or Ø 100mm) with a heat-resistant silicone plug, allowing you to connect power cables and signal wires to active test samples.

Q4: Can the temperature and humidity test profiles be customized?

Yes. The programmable LCD touchscreen controller allows you to set multi-segment temperature and humidity profiles, step ramps, hold times, and cyclic testing according to your specific test standards.

Q5: What warranty and after-sales support do you provide?

We offer a 3-year warranty and lifetime technical service. Free replacement spare parts are provided during the warranty period, alongside remote guidance, installation support, and operational training.
