For scheduled maintenance, you may to want to rotate the probes (as opposed to the
complete instrument) between the measurement site and a calibration laboratory. The
HygroClip product line is designed to make this easy. After removing the probe from the HygroFlex M transmitter, the following alternatives are available to calibrate the probe: |
- Calibrate the probe using a HygroPalm 3 indicator
- Calibrate the probe using a PC on which the HW3 software has been installed (requires the MOK-03-WIN calibration cable to connect the probe to the PC).
|

HW3 Software: software based probe calibration is both simple and precise: there are no hard-to-reach, hard-to-adjust potentiometers. HW3 offers a high level of flexibility in selecting the calibration reference, giving the user complete control over the calibration process. HW3 features the following calibration modes:
• Humidity: 2, 3 or 4 points
• Temperature: 2 points
• 1-point adjustment function (offset) for both humidity and temperature
When humidity calibration is done using the Rotronic humidity standards, HW3 automatically corrects the value of the standard to reflect the temperature of calibration (see note). HW3 also offers the possibility of printing a certificate of calibration.
Note: the value of the standards does not depend on barometric pressure (altitude). |
 |
Certified Humidity Standards: if you do not have access to a humidity generator, the Rotronic humidity standards offer a reliable and convenient way to generate a reference humidity condition during probe calibration. The Rotronic standards are shipped with an internationally accepted certificate, meeting in full the requirements of quality systems such as ISO 9000. The standards are available in boxes of 5 glass ampoules of the same value, and can be stored indefinitely. Standards in the range of 5 to 95 %RH are non-saturated aqueous salt solutions. The 0 %RH humidity standard is made of small granules of a highly porous ceramic. A Material Safety Data Sheet is available for each standard. |
 |
Calibration Devices: a calibration device is a small airtight container that fits on the probe and seals around the humidity sensor. During calibration, a known reference humidity is produced inside the calibration device by means of a humidity standard.
Four calibration devices are available for the HygroClip probes:
ER-15 for 15mm diameter probes
ER-05 for 5mm diameter probes
EM-15 for type ‘IE’ probes
ERV-15 for 15mm diameter probes (wall mounting) |
