Humidity Test Chamber: Precision Moisture Control for Material Performance Validation
Precision humidity control is necessary for environmental simulation in material testing. The Humidity Test Chamber offers specialised moisture conditioning without temperature interference to meet crucial testing needs for the electronics, pharmaceuticals, textiles and packaging sectors. Pure humidity testing equipment differs from mixed temperature-humidity systems in that it is concerned only with hygroscopic behaviour, moisture absorption rates and humidity related material deterioration. This product eliminates temperature variables, delivering cost-effective solutions for applications requiring constant ambient temperature with controlled relative humidity—from MSL classification to polymer water absorption analysis.

Core Design Features of Humidity Test Chamber
Ultrasonic Deionized Water Atomization System
Your humidity environmental chamber utilizes ultrasonic transducers generating 3~5μm cold mist from deionized water. This eliminates mineral deposits and organic contamination common with tap water systems. The atomization process operates without heating, preventing temperature drift and ensuring true humidity-only testing conditions.
Advanced Airtightness Technology
Moisture stability requires zero air infiltration. Our humidity resistance test chamber incorporates:
· Double-layer silicone dual-seal design: Creates hermetic closure preventing atmospheric moisture exchange
· Magnetic auto-lock door mechanism: Ensures uniform gasket compression regardless of operator force
· Fiberglass insulation walls: Minimizes condensation and thermal bridging
· Optional dew point meter integration: Real-time monitoring detects air leakage and triggers automatic humidification compensation
For ultra-low humidity applications (5%~10%RH), nitrogen purge ports enable inert atmosphere conditioning.
Double-Sided Horizontal Airflow
Unlike vertical flow systems creating stratification, our perforated rear wall design draws air uniformly, reconditions it, and redistributes it laterally. This humidity simulation chamber architecture delivers exceptional spatial homogeneity—critical when testing multiple samples simultaneously.

Frequently Asked Questions
Q: What's the difference between this and a temperature-humidity chamber?
A: This high product maintains ambient temperature while controlling only moisture—ideal when temperature isn't a variable.
Q: Can it achieve below 20%RH?
A: Standard models reach 20%RH. For lower levels, specify nitrogen purge option during order.
Q: How often does the ultrasonic transducer need replacement?
A: With deionized water, typically 5+ years. We supply spare parts globally within 48 hours.
Q: Is installation complicated?
A: Simply connect power and DI water supply. We provide video guidance and remote commissioning support.
Q: Does it comply with FDA 21 CFR Part 11?
A: Yes, optional APT-COM software enables audit-trail data logging meeting GLP/GMP documentation requirements.
