Our Resources page answers any concerns or questions about industrial weighing systems, scale repair & calibration. You will also find our full catalog of available manuals for our scales.



Why do we need to calibrate scales?

If scales are not calibrated or have fallen out of calibration, scales will begin to weigh incorrectly. This leads to inaccurate weighing. If you sell by the pound, you could be losing money or overcharging customers.

How often should scales be calibrated?

How often should scales be calibrated?
Scales and balances periodically need to be cleaned and calibrated to maintain their efficacy. During the service, an inspection and service report will be provided. The frequency should be based on risk factors and the consistency of the usage. High risk and high usage scale will require a shorter calibration interval (e.g., monthly).

By not calibrating scales there are risks associated as well as hidden costs with un-calibrated balances or scales which could be much higher than the cost of calibration itself. Using non-calibrated equipment can lead to production problems such as:

  • Unscheduled downtime
  • Inferior product quality
  • Process and audit issues
  • Product rework and recalls

Environmental changes can also lead to undetected drift or increasing random errors which will affect performance. Periodical scheduled calibrations is the best way to reduce calibration-related risk.

How do we calibrate scales?

We use the procedures described in the NIST Handbook 44 to inspect, calibrate, and certify scales.

Give us a call and a certified technician will contact you within 24 hours.

Why do scales get out of balance?

The day-to-day usage of these instruments leads to deterioration and inaccuracy over time. Depending on the frequency of usage and external factors will determine how often the scale will need to be calibrated.

Are scale calibrations required?

According to the Florida Department of Agriculture, Chapter 531, Section 61:

531.65 Unauthorized use; penalties. If a weights or measures instrument or device is used commercially without a valid commercial use permit, the department may do one or more of the following:

  1. Prohibit the further commercial use of the unpermitted instrument or device until the proper permit has been issued.
  2. Employ and attach to the instrument or device such form, notice, tag, or seal to prevent the continued unauthorized use of the instrument or device.
  3. In addition to the permit fees prescribed by rule for the commercial use of a weights and measures instrument or device, assess the late fee authorized under s. 531.62.
  4. Impose penalties as prescribed in s. 531.50 in addition to the payment of appropriate permit fees for the commercial use of a weights and measures instrument or device.
What is NIST?

NIST, commonly known as the National Institute of Standards and Technology, formerly the National Bureau of Standards (NBS), is the federal agency to which all precision measurements must be traced.

What is the difference between a scale and a balance?

Scales measure weight and balances tell you the mass of what is on the platform.

Do we need test weights in order to calibrate a scale?

In order to certify and correctly calibrate a scale, yes you do need test weights. However, if you are using it for reference, you may use other items to see if your scale is weighing within a normal range.

What is a load cell?

A load cell is a device that produces an output signal proportional to the applied weight or force. Types of load cells include beam, S-beam, platform, compression, and tension.

What is your return policy?

We accept returns within seven days of delivery. In addition to the “Return Authorization Form,” a written notice must be sent to Returns must be shipped back to us at the buyer’s expense. If goods are not rejected within the 7-day evaluation period, there is a 15% restocking fee.

Do the products have a warranty?

We do provide a 14-day limited warranty unless otherwise specified, from the date of delivery. The warranty will not apply to those goods that are damaged due to misuse, abuse, negligence, or notification by any party other than the seller. Most products also come with a manufacturer warranty that will apply. At the time of the purchase.

What is a custom weighing solution?

Scale Calibrators provides custom weighing solutions composed of more than a regular scale, gauge, or other simple force measurement device. Fully programmable weighing indicators requiring applications other than the factory default weighing modes are also considered a custom weighing system.

Do we sell and ship custom work?

Yes, we do!
