CALIBRATOR APPLICATIONS
UNPACKING INSTRUCTIONS
The GEO Hygro Max Humidity Calibrator generates and maintains a controlled humidity and tem-
perature environment for the purpose of testing or calibrating humidity and temperature sensors, also
known as hygrometers. The humidity calibration range is 1% up to 99%, while the temperature range
is from 0°C to 60°C.
See the full technical specications (page 25).
The system’s accuracy is achieved via a NIST traceable internal control and reference probe.
The Hygro Max can calibrate many hygrometer types:
• Probes
• Data-loggers
• Chart Recorders
• Additional Assorted Hygrometers
Please review the dimensions of the calibration chamber to ensure compatibility with the size require-
ments of any hygrometers you intend to calibrate. You may require an Expansion Chamber. Your
GEO representative should have reviewed this with you at time of purchase, if not, please contact our
support team and they will size an Expansion Chamber accordingly.
The Hygro Max allows for multiple types and sizes of hygrometers, for a complete list please contact
us at [email protected].
