One of the important services we provide for our clients are Weight Standard Verification Reports for their reference weights. The Weight Standard Verification Report from Analytical & Precision Balance Company shows the mean average based on 4 repeatability readings of a comparator between the client's reference weight and a Class 1 weight standard with NVLAP/NIST Traceablilty. This report shows the client's reference weight and/or weights have been submitted to a neutral non-biased lab for verification. The weight standards used in the verification process are Class 1 and are N.I.S.T. traceable. The Metrology Laboratory of the State of Arizona and the Metrology Laboratory of Rice Lake Weighing Systems certifies our weights annually. These weight reports are available to our clients for their Quality Control Records. We wish to point out the Weight Standard Verification Report issued by our company is for reference weights and not weights used in the calibration process. We have noticed many of our customers refer to their weights as calibration weights when in fact they are being used as reference weights. This often occurs during their day to day activities or during an audit that they are undergoing. This can open up a lot of questions or concerns as to what their weights are actually being used for, calibrations or reference checks. Virtually all of our clients are using their weights as reference weights.

With regards to weights used in calibration or in reference checks, Analytical & Precision Balance Company represents the leading weight standard suppliers. These include Troemner and Rice Lake. Feel free to contact us if you need help in deciding what specific weight standards you need and what level of Traceable Certification your weighing application requires.
