The Calibration Weights for Labs category includes the instruments, accessories and consumables needed to measure physical, chemical or mechanical properties and convert observations into data that can be compared, documented and acted upon. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately.
Instrument suitability, calibration and sample preparation all influence whether a result is repeatable and meaningful. For dependable results, compare calibration requirements, data handling, measurement range, and accuracy and resolution and confirm that the selected item is suitable for both the immediate task and the surrounding workflow.
A sound measurement workflow links representative sampling, suitable sensors or fixtures, calibration or verification, controlled testing and reliable recording of results. This coordinated approach is particularly useful in research, quality assurance, manufacturing, environmental, education and service laboratories, where repeatability and clear operating procedures matter. As part of the Analytical Measurement & Testing Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Calibration Weights for Labs range
Our collection covers touch calibration weights with bare hands, calibration weights formats, specifications and compatibility, calibration weights calibration, cleaning and maintenance, and e2 and f1 class weights, giving laboratories practical choices for routine work and more specialised applications.
Touch calibration weights with bare hands
Oils and moisture from your skin can alter the weight's mass; always use specialised tweezers or clean, lint-free gloves when handling high-precision weights. Key differences are usually found in calibration requirements, data handling, and measurement range. These details affect day-to-day usability as much as the main performance specification. This is especially valuable when teams need to produce consistent measurements while keeping calibration, sample handling and documentation aligned. Consistent handling also reduces the risk of variation between batches or operators.
Calibration Weights for Labs formats, specifications and compatibility
; for ISO-certified laboratories, weights should be periodically sent to a metrology lab for re-certification to ensure they have not drifted from their nominal value over time. Before ordering, compare data handling, measurement range, and accuracy and resolution. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. Used correctly, this part of the range helps laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. The result is a setup that is easier to train, document and maintain.
Calibration Weights for Labs calibration, cleaning and maintenance
Even microscopic scratches or dust accumulation can change the mass of a calibration weight; using a KERN padded case ensures the weight remains within its certified tolerance. Selection should take account of measurement range, accuracy and resolution, and sample type. It is also worth checking cleaning, replacement and storage requirements before the item becomes part of a routine procedure. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
E2 and F1 class weights
E2 class weights are high-precision standards used for calibrating analytical balances (readability 0.1mg), while F1 class weights are intended for precision balances with slightly lower resolution. The most suitable format depends on accuracy and resolution, sample type, and sensor or fixture compatibility. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. This is especially valuable when teams need to produce consistent measurements while keeping calibration, sample handling and documentation aligned. Consistent handling also reduces the risk of variation between batches or operators.
Featured brands

Frequently Asked Questions
Can I touch calibration weights with my bare hands?
Oils and moisture from your skin can alter the weight's mass; always use specialised tweezers or clean, lint-free gloves when handling high-precision weights. Laboratories should compare sensor or fixture compatibility, calibration requirements, and data handling and document the selected setup for consistent use.
Do calibration weights need to be re-certified?
; for ISO-certified laboratories, weights should be periodically sent to a metrology lab for re-certification to ensure they have not drifted from their nominal value over time. Laboratories should compare sensor or fixture compatibility, calibration requirements, and data handling and document the selected setup for consistent use.
Why should I store my weights in a padded case?
Even microscopic scratches or dust accumulation can change the mass of a calibration weight; using a KERN padded case ensures the weight remains within its certified tolerance. For calibration weights, also check sensor or fixture compatibility, calibration requirements, and data handling so the product fits the complete procedure.
What is the difference between E2 and F1 class weights?
E2 class weights are high-precision standards used for calibrating analytical balances (readability 0.1mg), while F1 class weights are intended for precision balances with slightly lower resolution. Laboratories should compare sensor or fixture compatibility, calibration requirements, and data handling and document the selected setup for consistent use.
How do I choose the right calibration weights for my laboratory?
The most important points are sensor or fixture compatibility, calibration requirements, data handling, and measurement range. Laboratories should also consider how the item will be stored, prepared, cleaned and replaced over its working life. Before ordering, confirm sensor or fixture compatibility, calibration requirements, and data handling and any accessories or consumables needed for routine use.
