All measuring instruments drift
with time. This is regardless of the brand, technology or measurement method. A
moisture meter is affected, for example, by chemicals, dust or other particles
in the air. Since instruments are placed in differing environments, it is
important to have continuous checks of each sensor, instrument and logger.
Failing to calibrate instruments regularly can be costly. You measure and
monitor to find, avoid and eliminate problems. Consequently, you have to ensure
that the equipment you rely on for this, is within required specifications.
Since the instrument will change slightly over time, it must be regularly checked.
A new logger from Intab is
well within the specification stated on the website and in our manuals and
brochures. Both the resolution and the overall uncertainty is specified.
It is not unusual that
calibration certificates with some instruments from other sources are insufficient
or just general specifications. It is therefore important to check the
information you get in a calibration certificate. We at Intab perform and rely
on traceable calibrations. We cooperate with accredited laboratories and are working
with traceable reference instruments.
How often you should
calibrate and how accurate calibration is required to be depends on your application
and its requirements. For measurements in tightly controlled industries such as
pharmaceuticals, it is often mandatory to calibrate once a year (voltage,
current and temperature) or more often (moisture every six months). In other
industries often experience will tell how often calibrations are needed. Most
common is, maybe because it's easy to remember, once a year.
Many years of experience
Intab has many years of
metrological experience and can offer advanced calibrations. We calibrate both
new and old instruments. With every, by us calibrated, device we supply a
certificate showing the measured results compared to the traceable reference
Now there is no need for
you to remember when the next calibration or service is to be made. Intab will send
you an e-mail when it is time. You just need to send your instrument and we'll
do the rest. Affordable and so much more practical for you.
To do this:
Send your logger to Intab
for calibration. The easiest way is to fill in the service document and include
it when you send in the loggers for calibration. Otherwise, supply the
information asked for below and include it with the package you send to Intab.
- Which loggers should be calibrated: type
and serial number?
- At what points do you wish to calibrate?
- Is there anything else you want done?
- How often would you like us to remind you
to send in the instrument for calibration?
- To which e-mail address should we send the
