Rotronic
HygroGen – Precision Humidity Generator & Calibrator
Accurate, reliable humidity calibration for laboratories and metrology
Precise humidity generation and calibration are critical whenever you need traceable humidity standards, especially in calibration laboratories, research facilities, and production quality centers. The Rotronic HygroGen provides a stable, controllable humidity environment that supports calibration, verification, and testing of humidity sensors and transmitters — supporting excellence in measurement, compliance and quality control.
Whether you’re certifying instruments to ISO standards, validating environmental chambers, or establishing internal traceability, HygroGen offers controlled humidity generation from low to high levels, with exceptional precision and repeatability.
Product Overview
The HygroGen is a humidity and temperature generator/calibrator that enables you to produce stable humidity conditions within a closed chamber — ideal for calibrating sensors and probes such as Rotronic’s own digital HygroClip™ series and other industry instruments.
Key capabilities include:
- Controlled humidity range: Typically from 5 % RH to 95 % RH (application and model dependent)
- Temperature control: Wide range for stable test environments
- Fast stabilization: Rapid attainment of target humidity conditions
- Uniform chamber conditions: Ensures repeatable results across sensor surfaces
Using advanced internal control and an intuitive user interface, HygroGen delivers high-accuracy calibration environments with minimal operator intervention.
How It Works
HygroGen uses a combination of:
- Reference quality sensors for feedback
- Closed-loop control systems to maintain humidity and temperature setpoints
- Low-noise chambers that minimize gradients and external influence
This allows the instrument to generate stable humidity levels for long periods — vital when performing calibration series, certification processes, or instrument comparisons.
Depending on configuration, your HygroGen unit can be fitted with:
- Large chambers for multiple probes
- Interfaces for external referencing or data logging
- Connectivity to software for test automation and documentation
