Scale Calibration

Scales can become out of calibration for a variety of reasons including wear and tear on components, environmental changes, buildup under the scale and more. The problem with a scale out of calibration is someone always loses.  In commercial transactions, either the seller is giving away free product or the buyer is paying for product he or she did not receive. Scale calibration is one of the core services provided by Quality Scales Unlimited.  Our technicians can calibrate any manufacturer or capacity of electronic or mechanical scale.  Our technicians use certified known weights, traceable to NIST to calibrate. After weight testing and calibration, we create Certificates of Calibration.  We can customize calibration certificates to meet your business needs.  Contact our service department for more information or a sample of our Certificates of Calibration.

Preventative Maintenance

Many times a scale is a business’s cash register; inaccurate weight readings and unexpected down time can lead to lost revenue.  One way to minimize these issues is to routinely perform preventative maintenance on your scale.  Below is the list of tests and inspections done during a Standard Preventative Maintenance appointment.  A regularly scheduled preventative maintenance service will extend the life of your scale, maintain accuracy, avoid equipment downtime and minimize repair expenses. Quality Scales Unlimited’s technicians can customize a preventative maintenance service designed specifically for your scale.  Call our service department for an appointment or more information.

Electronic scales now dominate the scale market and are driving mechanical scales and parts towards obsolescence. If you own a mechanical scale, you know replacing worn out or damaged parts can be pricey or even impossible to source.  One way to solve this problem is to convert your mechanical scale to electronic using load cells. Mechanical conversions begin with replacing a scale’s mechanical “weighing beam” with a load cell. Load cells installed within the mechanical system give the scale an electrical weight reading by measuring the load applied to the scale. The load cell’s electrical weight reading allows for data collection and printing, eliminating human error from hand written tickets. Mechanical conversions can be performed on almost all mechanical truck scales, hoppers and floor scales.  QSU has completed conversions for satisfied customers who report ease of use, greater accuracy as well as fewer costly repairs after their scale conversion. Out with the old weigh, in with the new!
