Scale Service & Calibration Contracts | Total Weighing Solutions
Service and calibration contracts are an effective way to keep your scales and weighing equipment accurate, safe and ready to use throughout the year. If your business depends on reliable weighing results, a planned maintenance contract can help reduce downtime, support compliance processes and extend the working life of your equipment.
At Total Weighing Solutions, we offer both Quarterly, 6-monthly and annual scale service and calibration contracts, tailored to suit your operational requirements. These contracts are especially valuable for mission-critical weighing equipment used in manufacturing, logistics, laboratories, warehousing, processing and industrial environments.
Why Regular Scale Servicing Matters
Scales that are regularly maintained generally work better, provide more reliable results and last longer. After all, a weighing scale is only useful if the results it provides are accurate and repeatable.
Our engineers check that your weighing equipment is operating correctly and within its own parameters. Where required, we can recalibrate equipment to bring it back into tolerance and provide documentation for your records.
What Is Included in a TWS Service and Calibration Contract?
For a fixed price, our engineers attend your site at an agreed time and carry out a structured inspection, service and calibration process. The aim is to ensure your scales are ready for use whenever you need them.
Typical duties include:
- Visual inspection of the weighing equipment
- Checks for physical damage, unsafe conditions or poor connections
- Linearity and repeatability testing
- Accuracy checks using certified test weights
- Recalibration where equipment is outside its own parameters
- Issue of a calibration certificate once testing is complete
Visual Inspection
One of the first checks we carry out is a visual inspection for physical defects. We look at whether the scale is connected correctly, free from damage and safe to use.
This is particularly important for weighing equipment used overhead, such as crane scales. If lifting or suspended weighing equipment is damaged or unsafe, the risk can be significant. Total Weighing Solutions is one of the few scale companies in the UK able to provide LOLER certificates for lifting equipment.
Linearity and Repeatability Checks
Reliable weighing equipment should produce consistent results. If the same load is applied several times, the scale should return the same reading each time. If half the load is removed, the reading should reduce accordingly. If the load is doubled, the indicated weight should increase in line with the applied load.
These checks help confirm whether the scale is behaving consistently across its weighing range. If results are inconsistent, our engineers will advise on the likely cause and any further work required.
Accuracy Testing with Certified Test Weights
Accuracy is checked by applying certified test weights to the scale and comparing the indicated reading with the applied load.
All scales, regardless of their accuracy class, operate within a defined tolerance. This tolerance is often based on the full-scale capacity of the equipment. Our engineers carry a wide library of calibration instructions for many different manufacturers, enabling them to recalibrate a wide range of weighing systems where required.
Calibration Certificate
Once the relevant tests have been completed and the accuracy of the scale has been confirmed, a calibration certificate is issued. This document details the tests performed and the results obtained, helping you maintain clear records for internal quality systems, audits and operational control.
6-Monthly vs Annual Calibration Contracts
The right service interval depends on how critical the scale is to your operation, how frequently it is used and the environment in which it operates.
| Contract Type | Best Suited For | Key Benefit |
|---|---|---|
| 6-Monthly Service and Calibration | Mission-critical scales, high-use equipment, harsh environments and process-critical weighing | More frequent checks help identify issues sooner and support ongoing accuracy |
| Annual Service and Calibration | General weighing equipment, lower-use scales and scheduled quality system requirements | Cost-effective planned maintenance and documented calibration records |
Benefits of a Scale Service Contract
- Improved reliability: Regular maintenance helps keep weighing equipment working correctly.
- Reduced downtime: Planned service visits can identify problems before they become more serious.
- Accurate results: Calibration checks help ensure your equipment remains within its required parameters.
- Fixed-price servicing: Know the cost of your planned service and calibration visits in advance.
- Convenient site visits: Our engineers attend your premises at an agreed time.
- Calibration documentation: Certificates are issued after successful testing.
- Discounted repairs: Contract customers receive a 10% discount on parts required for repairs outside the standard service duties.
Who Should Consider a Service and Calibration Contract?
A planned service contract is recommended for any organisation that depends on weighing equipment for production, quality control, dispatch, goods-in, batching, formulation, stock control or safety-critical applications.
Typical customers include:
- Manufacturers and production facilities
- Warehouses and logistics companies
- Laboratories and research facilities
- Food, chemical and pharmaceutical processors
- Engineering and fabrication businesses
- Companies using crane scales or lifting-related weighing equipment
- Businesses with audit or quality documentation requirements
Frequently Asked Questions
How often should scales be serviced and calibrated?
This depends on the scale, how often it is used, the working environment and how critical the weighing result is to your business. TWS offers both 6-monthly and annual service and calibration contracts to suit different operational needs.
Do you visit our site?
Yes. Under a service contract, our engineers attend your site at a convenient agreed time to carry out the required checks, servicing and calibration work.
What happens if a scale is outside tolerance?
If a scale is found to be outside its own parameters, our engineers will advise you. Where possible, they can recalibrate the scale and bring it back into tolerance.
Will we receive a calibration certificate?
Yes. Once the tests have been completed and accuracy is assured, a calibration certificate is issued detailing the checks performed and the results.
Are repairs included in the contract?
The standard contract covers the agreed service and calibration duties. If parts are required to repair a scale, these fall outside the standard service duties; however, TWS offers contract customers a 10% discount on required parts.
