Calibration

From industrial scale calibration to precision lab equipment, we can help you ensure accuracy

ISO 9001 Registered | ISO 17025 Accredited

Accuracy matters most

Click to  jump to the list of equipment we can calibrate

Inaccurate scales & measurement equipment can cost you money, time, and quality. Therefore, regular calibration is important. You can reduce the risk of overloading, underloading, or mixing improper proportions by ensuring the accuracy of your equipment.

Calibration is performed by state licensed, experienced technicians, with  certified test weights, and must be traceable to be valid.

Our experienced technicians service equipment ranging from heavy duty, industrial scales in harsh environments to high precision lab balances in controlled environments.

Each calibration performed includes a certificate, along with an “as found”, “as left” weight or measurement. We can help with torque wrenches, pressure gauges, micrometers, and calipers. Please see below or contact your local Michelli office for a complete list of our capabilities.

 

Need ISO 17025 Accredited Calibration?

Michelli has ISO 17025 accredited metrology labs and experienced calibration technicians. Let our team ensure your equipment or tools are up to your standards, as well as the standards required to meet compliance & safety guidelines.

 

Precision Measurement Equipment calibration in progress on granite surface plate

How often should you have your equipment calibrated?

The answer depends greatly on how much your profits, costs, labor or quality could be affected by an inaccurate measurement.

Legal for trade scales, including scales used in retail applications must be inspected & calibrated at a frequency set by the state.

Even if your precision measurement equipment was purchased elsewhere, we can perform calibration.

Standard Traceable Calibration

NIST is an abbreviation for the National Institute of Standards and Technology, which is a National Metrological Institute, (NMI) and a non-regulatory agency of the United States Department of Commerce. A Standard Traceable calibration ensures that your equipment has been compared to, and if necessary, adjusted to match, a standard that was calibrated and certified traceable to the SI Units through an NMI such as NIST.

Michelli Weighing & Measurement can provide Standard Traceable calibration service on equipment used to measure mass, lab balances, scales, physical dimensional tools, electronic tools, torque tools, force measurement equipment, temperature measurement equipment, and pressure measurement equipment.

ISO 17025 Accredited Calibration

In certain situations, ISO 17025 accredited calibration is required. These situations typically include critical applications, or those in which there is a high level of risk associated with inaccurate equipment. Basically, if the level of safety in a given situation could be compromised by inaccurate weighing & measurement equipment, ISO 17025 accredited calibration is typically required.

Michelli Weighing & Measurement can provide ISO 17025 accredited calibration service on equipment used to measure mass, lab balances, scales, physical dimensional tools, electronic tools, torque tools, force measurement equipment, temperature measurement equipment & pressure measurement equipment.

Certain ISO 17025 accredited calibration services cannot be performed on-site

In order to provide the lowest possible measurement uncertainty, certain types of physical dimensional calibration services must be performed in controlled environments & are only available in our ISO 17025 accredited calibration laboratories.

The controlled environment is also the reason that some physical dimensional calibration requires longer to complete. The physical dimensional equipment needs to acclimate to the conditions inside the calibration lab, which takes anywhere from 24-48 hours. This acclimation is necessary to allow the Michelli Weighing & Measurement calibration technicians to provide the lowest degree of measurement uncertainty (or highest accuracy) possible for your instrument.

Once equipment has acclimated to the calibration laboratory, the Michelli Weighing & Measurement technicians calibrate the equipment using traceable measurement standards. Lastly, the technicians perform the necessary calculations to certify the instrument & provide the customer with ISO 17025 certification.
