From industrial scales 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 NIST certified test weights, and must be NIST 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 offer torque wrench, pressure gauge, micrometer, and caliper calibration. Please see below or contact your local Michelli office for a complete list of our capabilities.

industrial scales

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.

Local Calibration is Important

Did you know centrifugal force, elevation & gravity could all affect scale accuracy? That’s why it’s very important to have your equipment calibrated locally. 

Regardless of where your scale was purchased, the Michelli service team can install & calibrate it for you.
