Today’s demand for world classproducts that perform better, last
longer, are more accurate and with-stand harsher environments has ledto an increased demand for certifiedcompliance with manufacturing stan-
dards. Many high-tech industriesdemand certificates of complianceand traceability in the manufacturing
process of the components they buy
from you, their vendors. Watlow is
able to meet this demand with ourcomplete testing and certificationservices.Watlow provides certification to verifythe finished sensor is built to allowinitial calibration tolerances as established by ASTM Standard E 230. This standard is based on the thermodynamic temperature
scale of ITS 90, succeeding IPTS 68.These are initial tolerances as sup-plied by Watlow. All sensors are susceptible to change during use
due to environmental factors such ascontamination, temperature,
industrial furnace
gradient and physical abuse.Watlow has the advanced capabili-ties to calibrate your sensors over a broad range of temperatures, from cryogenic -195°C (-320°F) to1700°C (3090°F).ISO 10012 is used as the guide for all sensor and instrument calibrationmaking all results traceable to theNational Institute of Standards and
Technology—NIST. Standard meth-ods and specifications for sensorcalibration used are:•ASTM E 207
•ASTM E 220•ASTM E 230•ASTM E 644
•AMS 2750C
We will test and certify any tempera-ture sensing product—whether madeby Watlow, or not. Our objective is to
provide you with a comprehensiveservice for determining compliancewith established standards.We will perform the tests and calibrations required and provide all necessary documentation for anadditional cost. >
