Saco, Maine - Any weight used to check a scale or balance belongs on a calibration schedule. That includes the reference weights a lab keeps on hand, the weight sets used for routine checks, and the standards other weights are compared against.
A weight calibration service in New England ties each of these weights to recognized standards, so the readings that depend on them can be trusted. LAW Calibration, a calibration laboratory in Saco, Maine, offers accredited mass calibration for customers across the region.
Which Weights Need Regular Calibration
Reference weights, also known as mass standards, form the highest level of the calibration chain. They are used to check other weights, so any error in them carries downward. Working weight sets are handled more often, in labs and on production floors, where they verify balances and scales day to day.
Handling and wear can change any weight over time. Regular calibration shows whether a weight still reads true.
LAW Calibration’s mass laboratory calibrates weights from Class 1 to Class 7, across a range from 1 mg to 25 kg. It works with weight sets from brands including Denver Instrument, INSCO, Rice Lake, Troemner, Ohaus, and Mettler Toledo.
Results are traceable to the SI system, and the lab holds A2LA accreditation to ISO/IEC 17025 (Certificate #2398.01).
What About the Scales and Balances?
Weights are only one side of the equation. The instruments they check need attention too. LAW Calibration calibrates scales, analytical balances, floor scales, platform scales, and triple beam balances.
Factory-trained technicians can work onsite, from microbalances to 1,000-pound platform scales. In the lab, precision analytical balances capable of measuring down to 0.0000001 grams, along with mass comparators, support the work.
How the Mass Lab Controls Its Conditions
Small changes in the environment can affect mass measurements. The lab holds temperature at 68°F and humidity between 20% and 60%.
A dedicated air circulation system helps control airborne contaminants, and marble comparator tables help reduce vibration. The lab follows environmental and procedural guidance from NIST and OIML.
LAW Calibration also tracks the equipment it calibrates and sends due date reminders at the frequency customers request. That helps teams keep weights and balances on schedule.
