Rotronic
HygroLab — High-Precision Benchtop Environment & Water Activity Measurement
A laboratory-grade humidity, temperature and water activity reference instrument
When laboratory accuracy and traceability matter — for product development, quality control or calibration purposes — the Rotronic HygroLab delivers the precision and flexibility you need.
Built as a rugged benchtop system, HygroLab provides simultaneous multi-probe measurement of humidity, temperature and water activity with fast response times, simple operation and excellent repeatability — making it ideal for laboratories and QA/QC environments.
Product Overview
The HygroLab is an integrated laboratory analyzer capable of using multiple Rotronic probes — typically HC2A, HC2S and HC2O — to measure:
- Relative humidity (RH)
- Temperature
- Dew point
- Water activity (aₙ)
Its benchtop design features an intuitive interface with a large color display, support for up to four measurement channels, and flexible communication options. HygroLab is designed to serve as both a reference instrument and a data acquisition platform for calibration labs, R&D facilities, and quality assurance teams.
Key Capabilities
Multi-Probe Operation
HygroLab supports simultaneous measurements from several probes, allowing you to measure different parameter sets in parallel — ideal for complicated or multi-location sample testing.
High Accuracy and Stability
When paired with advanced Rotronic digital probes, HygroLab delivers lab-grade performance across humidity, temperature and water activity, with traceable metrology and low drift over time.
Water Activity Measurement
Critical in food, pharmaceutical and material testing applications, HygroLab’s water activity functionality helps predict shelf life, microbial risk, packaging needs and product stability.
User-Friendly Interface
A clear color touchscreen, configurable displays and straightforward menu navigation simplify setup, measurement and data review — reducing operator training time.
Flexible Connectivity
HygroLab supports USB, Ethernet and digital outputs, allowing integration with LIMS (Laboratory Information Management Systems), data loggers or external PCs for advanced reporting and automation.
