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) |
