KERN 307-07 calibration weight — OIML Class E1, 100 g, polished stainless steel
KERN 307-07 is a precision test weight for laboratory and industrial calibration tasks, designed as a polished stainless-steel button for reliable use on analytical and precision balances.
- OIML Class E1 for highest accuracy
- Nominal value 100 g for calibration
- Polished stainless steel, button shape
- Tight tolerance 0.05 mg for traceable results
Accuracy that supports certified calibration workflows
High-precision metrology depends on reproducible reference masses. The KERN 307-07 meets OIML Class E1 requirements and offers a tolerance of 0.05 mg, making it suitable for calibration of analytical and high-precision laboratory balances. This level of specification reduces measurement uncertainty in calibration routines and supports quality assurance processes where minimal deviation is critical. The compact 22×38 mm cylindrical profile ensures secure placement on pans while maintaining a small footprint on the balance.
Durable finish and handling benefits for everyday laboratory use
A polished stainless-steel construction provides corrosion resistance and a smooth surface that eases cleaning after use. The button form factor improves handling on tiny balance pans and minimises tipping or contact errors during transfers. Thanks to the robust finish, the reference mass sustains repeated handling without rapid surface degradation, which contributes to long-term stability and lowers the frequency of recalibration required in routine workflows. A compact mass of 100 g and a practical shape support efficient operation in busy calibration environments.
Designed to integrate into traceable quality systems
The product’s adherence to OIML Class E1 supports traceability demands for accredited laboratories and internal quality systems. The precise specification—combined with manufacturer identification and SKU for inventory—simplifies record keeping and procurement within a calibrated equipment register. For preservation of the weight’s accuracy, storage in a protective case is recommended; this reduces contamination and mechanical wear that would otherwise affect measurement fidelity. The clear technical specifications allow straightforward comparison with regulatory requirements and laboratory procedures.
Practical applications and recommended care
Intended primarily for metrology labs, calibration service providers and precision workshops, this reference mass is ideal where exact mass values are necessary for verification and adjustment of analytical balances. Handling advice: minimise fingerprints and grit contact, store the mass in a protective case when not in use, and follow the laboratory’s cleaning and recalibration schedule to preserve conformity with the stated 0.05 mg tolerance. The compact stainless-steel construction enables use across a variety of controlled environments without introducing material compatibility concerns.

FAQ
What accuracy and tolerance does this reference mass provide?
The KERN 307-07 calibration weight is specified as OIML Class E1 with a tolerance of 0.05 mg, suitable for calibration of analytical and high-precision balances.
Is this weight intended for laboratory calibration or field use?
This 100 g reference mass is intended primarily for laboratory and calibration service use; the Class E1 specification supports controlled calibration procedures rather than rough field checks.
How should the mass be stored to maintain accuracy?
Store the KERN 307-07 in a protective case when not in use, avoid direct handling with bare hands where possible, and keep it in a stable, clean environment to preserve the stated tolerance.
Which balances can be adjusted with this weight?
The weight is suitable for analytical and precision balances that require a 100 g reference mass for verification or adjustment within a laboratory calibration workflow.
Does the product require special handling during measurement?
Handle the KERN 307-07 with clean gloves or tweezers and place it gently on the balance pan; a protective case is recommended to prevent contamination and preserve long-term stability.
