Product information
Relative humidity control
HUM-1
Humidity generator provides constant humidity though feedback control by simply setting the target relative humidity (RH). It is suitable for generating humid gas at a relatively small flow rate of several hundred mL per minute, and is ideal for thermal stability testing, continuous measurements of hygroscopic and dehydration changes in a humid atmosphere.
HUM Features
- Type: Divided-flow type (single tank bubbling method), feedback control of dry gas flow by temperature and humidity sensors placed near the test sample
- Humidity stability: Within ±2% RH (excluding transient states during setting changes)
