Full Range of Services: Laboratory and On-Site Calibration

On-Site Calibration - We Come to You

Laboratory Calibration — You Send the Weighing Instruments to Us

Our calibration laboratory provides professional on-site calibration of weighing instruments with capacities of up to 80 kg directly at the customer’s premises. This option is particularly convenient for companies where weighing instruments are installed in production areas or where moving them is undesirable or technically difficult.

Calibration at the equipment’s actual place of use makes it possible to assess its performance under real operating conditions, avoid transportation-related risks, and minimise downtime.

On-Site Services We Provide:

Calibration of weighing instruments with capacities of up to 80 kg
Recalibration to verify accuracy and compliance
Testing of weighing instruments according to their accuracy class
Issuance of a calibration certificate with traceability to national measurement standards

You choose a convenient date and time and provide us with a list of the equipment. Our specialist will contact you promptly to confirm all organisational details.

Your Benefits:

Minimal equipment downtime
Calibration under the actual operating conditions of the weighing instruments
No risk of damage during transportation
Flexible choice of date and time

This option is convenient for new instruments and weighing equipment that can be transported easily and safely. In this case, there is no need for an on-site visit by a specialist, and all work is carried out under controlled laboratory conditions, allowing the calibration to be performed with maximum accuracy.

How the Process Works:

Day 1: You send the weighing instruments to our calibration laboratory.
Days 2–3: Our specialists inspect the equipment, assess its metrological characteristics, and perform the calibration.
Day 4: After successful inspection and issuance of the calibration certificate, the weighing instruments are returned to the customer.

Advantages of This Method:

Fast turnaround:
- standard calibration: up to 4 business days;
- expedited service is available upon individual request.
High accuracy: calibration is performed under controlled laboratory conditions using reference weights and high-sensitivity measuring equipment.
Flexibility: we calibrate weighing instruments from various manufacturers and of different models.
Comprehensive approach: under laboratory conditions, we ensure accurate and reproducible calibration in accordance with established procedures and metrological requirements.

FAQ - Calibration of Non-Automatic Weighing Instruments

What are non-automatic weighing instruments (NAWIs)?

Non-automatic weighing instruments are scales or balances that require the operator to perform one or more actions during use, such as placing the load, initiating the weighing process, or reading the result. NAWIs include laboratory balances, platform scales, retail scales, medical scales, and other weighing instruments that do not operate in a fully automatic mode.

Why is weighing instrument calibration necessary?

Calibration confirms the accuracy of weighing instrument readings and ensures compliance with metrological requirements and standards. Without regular checks, measurement errors may occur, affecting product quality, measurement results, and compliance with regulatory requirements.

How often should calibration be performed?

Calibration is recommended at least once a year. For critical processes or frequently used weighing instruments, the interval may be shortened. The calibration frequency may also be determined by the company’s internal quality management procedures.

What types of weighing instruments do you calibrate?

We calibrate all types of non-automatic weighing instruments with capacities of up to 80 kg, including:

analytical and precision laboratory balances,
technical and bench scales,
platform scales,
retail scales,
medical and specialised weighing instruments,
mass comparators.

What is the difference between laboratory calibration and on-site calibration?

Laboratory calibration is performed under controlled conditions to achieve the highest possible accuracy.

On-site calibration is carried out at the customer’s premises. This option is convenient for equipment that is difficult to transport and helps minimise downtime.

What certificate will I receive after calibration?

After the work is completed, you will receive a calibration certificate containing the actual measurement values, measurement uncertainty, the calibration method, and traceability to national measurement standards in accordance with ISO/IEC 17025.

Do you calibrate weighing instruments from any manufacturer?

Yes. We work with equipment regardless of brand or model, provided it falls within the applicable measurement range and meets the technical calibration requirements.

Do you provide weighing instrument adjustment or repair services?

Our laboratory specialises specifically in calibration. When required, we can recommend partner service centres for repairs or adjustments.

Is urgent calibration available?

Yes. Expedited laboratory calibration is available upon request. The turnaround time is agreed individually depending on the type of equipment and current laboratory workload.

Can weighing instrument and weight calibration be combined?

Yes. We offer calibration of weights and non-automatic weighing instruments within a single service cycle, helping optimise the process and reduce time costs.
