Humidity Control
CHG300

The CHG300 is a humidity generator perfectly suited for midsize volumes like gloveboxes or enclosures. The CHG300 offers dynamic humidity control for chamber volumes up to 500 l and static control for chamber volumes up to 1000 l. This allows testing under controlled climatic conditions while maintaining flexibility in both setup and test equipment.

CHG300-TC

The CHG300 TC (Temperature Control) is a humidity generator perfectly suited for midsize volumes like gloveboxes or enclosures. The CHG300-TC offers dynamic humidity control for chamber volumes up to 500 l and static control for chamber volumes up to 1000 l. This allows testing under controlled climatic conditions while maintaining flexibility in both setup and test equipment.

Key Features of the CHG300:

The CHG300 is designed for controlled humidity in midsize to large test chambers, gloveboxes or other applications where specific moisture content is required. Its powerful design enables fast humidity control and is well-suited for use with materials that exhibit high water adsorption, or even in semi-open systems. The TC option allows temperature control in the target system.

State of the Art Design

This modern patent pending design is capable of powerful humidification and uses efficient constant circulation for fast humidity regulation. The 10” touchscreen display allows easy, intuitive operation. The CHG300 is equipped with customizable attachment options for the target system. The air outlets can be positioned on either side of the instrument, and the versatile outputs offer multiple options to attach to the target system.

Precise Control

Closed-loop control: The CHG300’s humidity and temperature sensor is ideally located within the target system close to the device under test. This sensor placement enables the CHG300 to deliver fast, stable, and robust control performance. Constant circulation inside the target system ensures a homogeneous climate and reduces carrier gas consumption.

Temperature and Humidity Regulation

The TC option allows the use of Peltier modules with up to 550 W electrical power for heating and cooling operation. A variety of Peltier modules is available on request. Operating limits depend on user specific application.
