Test weights are essential tools used to verify, calibrate, and maintain the accuracy of weighing systems across a wide range of industries. Whether you're operating heavy industrial machinery or sensitive laboratory equipment, precision matters. At LES - Lifting Equipment Store, we provide high-quality, certified hand test weights that help ensure your equipment is performing accurately and consistently — every time.
What Are Test Weights?
Test weights are specially designed and precisely calibrated masses made from durable materials such as cast iron, stainless steel, or brass. They are manufactured to meet strict national and international standards, and each one is certified for accuracy. These weights serve as benchmarks to test and adjust weighing equipment, ensuring readings are as close to the true value as possible.
Accurate hand test weights are not just helpful — they are essential for any industry where precision is non-negotiable.
Where and How Are Test Weights Used?
Test weights & hand test weights are used in a wide variety of applications, including:
- Calibrating Weighing Equipment: Whether you're using platform scales, floor scales, or crane scales, test weights are used to check and fine-tune calibration. This keeps your systems working within their intended tolerances.
- Quality Control in Manufacturing: In production environments, accuracy is key to maintaining quality standards. Regular calibration with test weights ensures product consistency and reduces costly errors or recalls.
- Counterbalance for Gantry Cranes and Lifting Equipment: Test weights are often used as counterbalances during installation or load testing of cranes, hoists, and lifting gear to verify lifting capacity and safety.
- Compliance with Legal and Industry Standards: Many industries must comply with strict regulatory requirements for weighing accuracy. Test weights help meet ISO, UKAS, or other calibration standards, ensuring your business stays audit-ready.
- Scientific Research and Laboratory Settings: In labs where minute measurements can affect the outcome of experiments, certified test weights are used to calibrate analytical and precision balances.
From food production lines and shipping warehouses to construction sites and laboratories, test weights play a critical role in day-to-day operations and long-term equipment reliability.

Test Weight & Calibration FAQs
Yes, test weights can be used to calibrate both digital and mechanical (non-digital) weighing systems, ensuring they remain accurate and reliable. For mechanical systems, the weights are typically used to check spring balances or load cells.
Certified test weights are calibrated and verified to meet specific national or international standards, making them suitable for high-accuracy applications. Non-certified weights are typically used for less stringent calibration needs. For industries that require compliance with regulations, certified test weights are recommended.
When using test weights outdoors, ensure they are protected from exposure to weather, dirt, or extreme temperature changes, as these conditions can affect their precision. Using weights that are specifically designed for outdoor use, such as those made from corrosion-resistant materials, is recommended.
To maintain the accuracy of test weights, store them in a controlled environment away from extreme temperatures, moisture, or physical damage. Regularly calibrating and using certified weights ensures they remain within tolerances and provide reliable results.
If a test weight is dropped or damaged, it may no longer provide accurate calibration. Inspect it for any visible signs of damage or wear, and if necessary, return it for recalibration or replacement to maintain the integrity of your measurements.
