One of Rotronic's HygroGen2 generators

Alpha Controls & Instrumentation Inc. supplies measurement solutions by Rotronic – including the unique HygroGen2 series of temperature and humidity generators. Designed for businesses that need to calibrate many probes regularly, these portable multipoint calibrators function like mobile calibration laboratories, setting a new standard in the field.

Providing numerous outstanding advantages, especially in pharmaceuticals, the HygroGen2 line enables simple, flexible calibration that allows fast reintegration of calibrated instruments into operations.

Equilibrium humidity in five minutes

Each HygroGen2 device generates a stable reference environment for humidity between five and 95 per cent RH. The calibrator typically reaches equilibrium humidity in five minutes and is appropriate for all humidity and temperature probes. Other features include an easy-to-use touchscreen monitor, a DVI interface for the external monitor, a USB interface for keyboard, mouse, and USB connections, and integrated HW4 software that ensures simple calibration and probe adjustment.

With the HygroGen2 series, users calibrate multiple probes at once. The standard device comes with external heated connections for a dewpoint mirror reference. This way, reference points can be adjusted with high precision, while total calibration uncertainty can be lowered. An ultraviolet sterilizer keeps water quality high, preventing bacteria and algae from forming.

Optional features of these instruments include:

  • AutoCal. Automated calibration of multiple HC2 probes connected by an AC3001 USB adaptor.
  • Range extensions. Users can extend temperature range down to minus five degrees Celsius or the humidity range, typically five to 95 per cent RH, to two to 99 per cent RH.
  • External MBW/RHS reference integration. Further extension of generator utility.
  • Remote screen sharing. A larger screen interface used via another device.

Rotronic has developed an upgrade of these devices, the HygroGen2-XL, also available from Alpha Controls. This unit has a chamber with ten times the capacity and reaches equilibrium humidity in 15 minutes, while offering the same rock-solid stability, minimal thermal gradients, and rapid time for setpoint changes.
