Our calibration process involves several comprehensive steps:

1. Initial Assessment

   • Visual inspection of the scale for physical damage or wear

   • Verification of proper setup and environmental conditions

   • Functional testing of all displays, controls, and features

1. Zero Balance Check

   • Testing and adjusting the zero reading with no load

   • Checking for drift and stability at zero

1. Linearity Testing

   • Multiple test points across the scale's range (typically 5-10 points)

   • Testing with certified reference weights traceable to NIST standards

   • Verification of accuracy at different load positions (corner tests)

1. Repeatability Testing

   • Multiple measurements at the same weight to ensure consistent readings

   • Evaluation of standard deviation between repeated measurements

1. Calibration Adjustments

   • Making necessary corrections to bring the scale into specification

   • Fine-tuning to ensure optimal performance

1. Post-Calibration Verification

   • Verification testing to confirm calibration was successful

   • Documentation of before and after readings

1. Documentation

   • Creation of calibration certificate with all test results

   • Recording environmental conditions and test equipment used

   • Applying calibration sticker with date and next due date

1. Consultation

   • Recommendations for maintenance or repairs if needed

   • Guidance on proper use and environmental considerations

• Laboratory scales - precision analytical balances, microbalances, and other high-accuracy measurement instruments

• Agricultural scales - livestock scales, grain scales, feed scales, truck scales, and field equipment

• Retail scales - point-of-sale scales, deli/meat/produce scales, price computing scales

• Industrial scales - bench scales, floor scales, drum scales, tank/hopper scales, crane scales

• Medical scales - patient scales, pharmacy scales, infant scales

• Specialty weighing equipment - moisture analyzers, pill counters, jewelry scales, postal scales

We offer both on-site and in-lab calibration services:

On-site:

• Technicians come to your location with NIST-traceable weights

• Minimizes downtime and eliminates shipping

• Calibrates equipment in its actual operating environment

In-lab:

• Controlled environment for highest precision

• Access to full range of specialized equipment

• Often more cost-effective for smaller scales

We'll recommend the best option based on your specific equipment and needs.

Commercial scales should typically be calibrated:

• Annually as a minimum baseline for most standard commercial applications

• Semi-annually (every 6 months) for scales in high-usage environments or critical applications

• Quarterly for scales used in highly regulated industries or harsh environments

• After any repair, maintenance, or physical relocation of the equipment

• Following any significant impact or damage to the scale

• When accuracy issues are suspected or drift is observed in measurements

• In accordance with your specific industry regulations (some require more frequent calibration)

The optimal calibration frequency depends on several factors including the scale's usage intensity, environmental conditions, accuracy requirements, and regulatory demands specific to your industry.

Using improperly calibrated scales in your business can lead to significant costs across multiple areas:

• Financial Losses:

  • Giving away product ("scale give-away") from under-weighing when selling by weight

  • Revenue loss from over-weighing when purchasing by weight

  • Inventory discrepancies leading to poor ordering decisions

  • Production inefficiencies from improper ingredient proportions

• Regulatory Consequences:

  • Fines and penalties from weights and measures inspections

  • Failed audits from FDA, USDA, or other regulatory bodies

  • Potential business license issues or operational shutdowns

  • Legal exposure from non-compliance with trade regulations

• Customer Impact:

  • Loss of customer trust if discovered selling incorrect weights

  • Damage to business reputation and brand integrity

  • Potential for customer complaints or negative reviews

  • Loss of repeat business and referrals

• Product Quality Issues:

  • Inconsistent product quality from improper ingredient measurements

  • Increased waste and product rejections

  • Reduced shelf life or product performance

• Hidden Operational Costs:

  • Increased production variance and quality control problems

  • Higher material waste from inconsistent measurements

  • More time spent troubleshooting production issues

  • Unnecessary product giveaway eroding profit margins

Yes, all our calibration services are fully traceable to NIST standards. We maintain ISO/IEC 17025 Accreditation (#100513) and use NIST-Traceable Standards for every industry we serve.

This accreditation demonstrates that our calibration procedures, equipment, and technicians meet internationally recognized standards for technical competence. Each calibration we perform includes documentation that establishes an unbroken chain of traceability back to NIST (National Institute of Standards and Technology).

ISO/IEC 17025 specific requirements for testing and calibration laboratories

After completing a calibration, we provide comprehensive documentation that includes:

• Calibration Certificate with unique identification number

• Test results showing before and after measurements

• List of standards used for the calibration

• Traceability information linking to NIST standards

• Uncertainty calculations for the measurements

• Acceptance criteria and pass/fail determinations

• Calibration date and recommended recalibration date

• Technician information and signature

• Environmental conditions during calibration (temperature, humidity)

• Any adjustments or repairs made during service

• Statement of conformance to specified requirements

All documentation is provided in both digital and hard copy formats for your record-keeping requirements. These documents satisfy audit requirements for ISO, FDA, USDA and other regulatory bodies.
