SummaryPortable reference generator for the calibration of humidity and temperature measuring instruments. The HYGROGEN2 – XL (Rotronic) is a portable calibration laboratory providing high stability, an increased chamber capacity and on-site or laboratory deployment. It enables simultaneous calibration of multiple sensors and meets quality and compliance requirements (suitable for ISO 17025 contexts).
Key features- Generates stable humidity and temperature conditions (typical stability <+/- 0.1 %RH, <+/- 0.01 °C).
- Humidity equilibration time under normal conditions: approximately 15 minutes.
- Allows simultaneous calibration of several sensors and data loggers.
- Chamber volume: 20 liters (effective working volume: 17 liters).
- Fast setpoint changes and low temperature drop during insertions.
- AIRCHIP digital technology and integrated Rotronic HW4 software (FDA 21 CFR Part 11 compliant).
Portable calibration laboratory – strengths- System suitable for laboratory use or on-site interventions, allowing complete qualification close to the devices under test.
- Exceptional stability, rapid setpoint changes and increased chamber capacity on the XL version.
- Interfaces and extensibility for automation and integration (USB, Ethernet, optional Remote API).
