Toledo Transducers' calibration facilities are accredited by A2LA - The
American Association for Laboratory Accreditation. This accreditation assures our customers
that their load cells have been calibrated in conformity with national standards. We make
every effort to design and the build the highest quality load cells. Providing high quality
calibrations is an integral part of our quality system; insuring our customers the best
products.
We provide three basic levels of calibration service:
ACCREDITED ASTM E74 is the highest level of calibration that we offer. It requires three
runs of ten points each (in addition to 'as received' data.) Each of the three runs is taken
along a different axis of the load cell. Because we gather significantly more information
about the load cell, this method provides the most accurate description of the load cell's
performance characteristics. Obviously, this is also the most expensive type of calibration
and is normally required only in special circumstances.
ACCREDITED ISO/IEC 17025 is the most common type of calibration. This method consists of
two runs of five data points each. While this provides less data than the ASTM E74 method,
it is normally adequate for most uses.
ACCREDITED SINGLE POINT COMMERCIAL calibrations consist of recording the maximum load twice,
with a zero return between the two points. While this yields only very limited information,
it is an efficient and inexpensive of insuring that the load cell is in proper working order.
ASTM recommends re-calibration of load cells once every year, and more often where there is
reason to suspect possible damage has occurred. A certified calibration is the only way to be
certain that your load cells are providing you with accurate information. Our A2LA accredited
laboratory can verify that your load cells are working reliably and providing you with accurate
information. |
