HygroLab – High-Precision Water Activity Measurement for Laboratory Use
When your work depends on accurate water activity data, both measurement precision and repeatability are critical.
Small deviations can impact product quality, shelf life, and documentation.
The Rotronic HygroLab is designed for laboratory environments where you need reliable, traceable measurements of water activity, humidity, and temperature.

When Measurement Accuracy Must Be Trusted
Water activity measurement is sensitive to both environmental conditions and measurement method. If your setup is not stable or consistent, results can vary – even for identical samples.
In practice, this creates challenges such as:
- Uncertainty in quality control results
- Difficulty comparing measurements across batches
- Risk of incorrect conclusions in R&D or validation work
HygroLab addresses this by providing a controlled, high-precision measurement platform designed for repeatable results.
Multi-Channel Measurement for Efficient Workflows
HygroLab allows you to measure multiple samples simultaneously.
- Up to four measurement channels
- Parallel analysis of different samples
- Consistent measurement conditions across all channels
This is particularly useful when you:
- Work with multiple batches or formulations
- Need to compare samples under identical conditions
- Want to improve throughput in laboratory workflows
Designed for Stable and Repeatable Measurements
Reliable water activity measurement depends on achieving equilibrium between the sample and surrounding air.
HygroLab supports this by providing:
- Stable measurement chambers
- High-precision humidity and temperature sensors
- Consistent measurement conditions across tests
In practice, this means you can trust that differences in results reflect the product – not the measurement setup.
One Instrument – Multiple Parameters
HygroLab is not limited to water activity.
With Rotronic’s digital probes, you can measure:
- Water activity (aw)
- Relative humidity (RH)
- Temperature
- Derived values such as dew point
This gives you flexibility to use the same platform across different applications.
Faster Analysis with AW Quick Function
In traditional water activity measurement, you need to wait until equilibrium is fully reached before the result can be trusted. Depending on the sample, this can take considerable time.
With Rotronic’s AW Quick function, HygroLab allows you to reduce this waiting time significantly.
The system monitors the early part of the measurement curve and predicts the final result using a validated algorithm. This means you can obtain reliable results without waiting for full stabilization in every measurement.
For you, this results in:
- Faster sample analysis in daily laboratory work
- Improved efficiency in quality control processes
- Reduced waiting time without compromising measurement quality
This makes HygroLab particularly well suited for environments with high sample throughput or time-critical decisions.
The AW Quick function is also available in Rotronic AwTherm.
Flexible Use with Rotronic Probes and Accessories
HygroLab works with a wide range of Rotronic probes and accessories:
- Interchangeable digital HygroClip probes
- Sample holders for different product types
- Compatibility with AwTherm for temperature-controlled measurements
This allows you to adapt the system to your specific application – whether you work with powders, liquids, or solid materials.
Applications in Laboratory and Quality Control
HygroLab is widely used in environments where water activity plays a critical role:
- Food and beverage – shelf life, texture, and microbial stability
- Pharmaceuticals – product integrity and compliance
- R&D laboratories – formulation and stability studies
- Quality control – batch verification and documentation
What This Means for Your Work
With HygroLab, you get:
- Reliable and repeatable measurements you can base decisions on
- Efficient workflows with multi-sample capability
- Flexibility to measure multiple parameters in one system
- Confidence in your data for documentation and compliance
