Calibration is performed by state-certified technicians using certified test weights, weight carts, and test trucks, following NIST Handbook 44 standards and state weights and measures regulations. All calibrations produce NIST-traceable documentation including before-and-after measurement data and uncertainty analysis — suitable for FDA, ISO, AS9100, and legal metrology requirements. **Types of scales calibrated:** **Laboratory Balances** — High-precision analytical and precision balances used in pharmaceutical compounding, chemical analysis, R&D, semiconductor processing, clinical laboratories, and academic institutions. Requires controlled-environment calibration using ASTM Class 1 reference weights. Even small vibrations, drafts, or temperature changes can affect accuracy — Scale Service & Supply understands the specialized handling these instruments require. **Floor Scales** — Heavy-duty platform scales for warehouse, manufacturing, shipping, and industrial applications. Calibrated on-site using certified test weights and weight carts. Floor scales must be calibrated at their location of use — moving them affects accuracy. Capacity range covers components and assemblies to bulk material and multi-ton loads. **Counting Scales** — Weighing systems that determine piece counts through precise weight measurement, used for inventory management, parts tracking, kitting, and quality control. Common in aerospace, electronics, automotive, and general manufacturing. Calibration ensures piece-count accuracy across a wide range of part weights. **Belt Scales** — Continuous weighing systems integrated with conveyor belts for real-time measurement of bulk materials in motion. Used in construction materials, energy, chemical manufacturing, and utilities. Calibration addresses dynamic weighing conditions, belt speed, and environmental factors for accurate ongoing measurement. **Truck Scales** — Large-capacity platform scales for weighing loaded trucks, vehicles, and heavy freight. Essential for construction, waste management, agriculture, logistics, utilities, and government weight enforcement. Scale Service & Supply uses certified test trucks for truck scale calibration, ensuring legal compliance for commercial transactions and DOT weight enforcement. **Railroad Track Scales** — High-capacity weighing systems integrated into rail infrastructure for weighing railcars and locomotives, either in motion or at rest. Used by energy companies, utilities, chemical manufacturers, and bulk material shippers that move product by rail. Calibration ensures accurate freight billing, inventory, regulatory compliance, and load safety verification under demanding conditions. **Common questions about scale calibration:** - *How often should scales be calibrated?* Annual calibration is standard for most applications; regulated industries (pharmaceutical, food, commercial) may require more frequent calibration or after any move, repair, or significant environmental change. - *Should scales be calibrated on-site or sent to the lab?* Floor scales, truck scales, belt scales, and railroad track scales must be calibrated on-site — shipping affects accuracy. Laboratory balances may be calibrated in-lab under controlled conditions. - *Do you calibrate truck scales?* Yes — Scale Service & Supply uses certified test trucks and can calibrate truck scales throughout New York and surrounding states. - *Do you calibrate railroad track scales?* Yes — one of very few calibration companies in the Northeast offering railroad track scale calibration. - *Do you provide NIST-traceable calibration certificates?* Yes — all calibrations include full NIST-traceable documentation with before-and-after data. - *Do you calibrate laboratory balances?* Yes, including analytical and precision balances for pharmaceutical, research, and food safety applications. - *Do you calibrate belt scales?* Yes — including dynamic calibration for conveyor belt systems. - *What brands of scales do you calibrate?* All major brands including Rice Lake, Ohaus, Cardinal, Mettler-Toledo, Sartorius, Fairbanks, and others. --- ### Scale Service and Maintenance [Service & Maintenance](https://thescale.com/service-and-maintenance): Scale Service & Supply offers a complete range of service and maintenance solutions for weighing equipment, designed to minimize downtime, extend equipment life, and ensure ongoing compliance.
