Accurate weight measurement is critical in industries like pharmaceuticals, food processing, manufacturing, and laboratory testing. One essential tool for this accuracy is the weight box, used to verify and calibrate balances and scales so they perform within strict tolerance limits.
Over time, due to regular usage, environmental exposure, and handling, the actual values of weights may deviate. To ensure compliance, avoid costly errors, and maintain consistent product quality, regular weight box calibration becomes a necessity.
Whether it’s a standard weight box used for general calibration or an analytical weight box for ultra-precise testing, calibration from a NABL-accredited lab ensures accuracy and peace of mind. That’s where Prism Calibration comes in — your trusted partner in precision.
At Prism Calibration, we offer expert services for a wide range of weight boxes tailored to your application and accuracy requirements.
Used in labs and industry, these boxes contain sets of known weights for balance verification and general calibration tasks. Suitable for standard quality checks and process validations.
Designed for sensitive environments like research labs and pharma, these weight boxes are used with microbalances and require extremely fine calibration in a controlled setting.
F1 and F2 Class Weights – Offer better accuracy, used in high-precision lab and QA applications.
We calibrate all classes of weights as per NABL standards, ensuring full traceability and reliable measurements.
We follow a systematic, standards-compliant process aligned with ISO/IEC 17025 and NABL guidelines.
Each weight is checked for corrosion, physical damage, or contamination.
Weights are cleaned and stabilized in a controlled temperature/humidity environment.
Using mass comparators and traceable standards, we ensure accurate comparison.
