OV Scale & Instruments calibrates and repairs scales, lab balances, and instruments such as calipers, micrometers, torque wrenches, thermocouples, ovens and pressure gages. We can simplify your management by consolidating all of your calibrations under one vendor and contract. Our technicians can perform many calibrations at your site, and at our climate-controlled accredited metrology laboratory.

We will manage your calibration schedule, to make sure your devices are calibrated on time.

We can handle the engineering, construction, installation, calibration, and employee training for your scale project.  This includes retrofits where we have to modify an existing foundation to accommodate a new scale.  

Extreme Capacity Testing and Calibration

With over 250,000 lbs in NIST Traceable Certified Test Weights, we can calibrate your truck, rail, platform and crane scales in the high capacity range where they are used, not just in the lower ranges that may not reflect errors seen at higher capacities.  This can be extremely important to assuring accuracy in your process.

We rent up to 200,000 lbs in NIST Traceable Weights to crane and elevator service companies. Click here for more information on test weight rentals for crane and elevator service.
