KERN 304-06 Weight set (OIML E1, 1 g–1 kg)

A weight set designed for high-precision calibration of laboratory and industrial balances, supplied in a protective wooden case

• OIML E1 accuracy class
• Nominal range 1 g–1 kg
• Polished stainless steel weights
• Supplied in wooden storage case

Highest accuracy for legal and laboratory calibrations

The OIML E1 classification denotes the highest tier of international legal metrology for small mass standards; this ensures minimal measurement uncertainty when verifying analytical and microbalances. The calibration masses cover a nominal range of 1 g–1 kg, which makes them suitable for traceable checks across common laboratory capacities. Using calibration masses of this class supports compliance with regulatory requirements and reduces the need for repeated adjustments, delivering a measurable improvement in process reliability and measurement confidence.

Robust manufacture and ergonomic handling for frequent use

Manufactured from polished stainless steel, the masses resist corrosion and maintain surface integrity after repeated handling, which preserves traceability over time. The knob shape design simplifies handling and placement on balance pans, reducing the risk of contact-induced errors. Supplied in a fitted wooden case, the set is protected from contamination and mechanical damage during storage and transport. Together these features mean less downtime for maintenance and a longer service life for the weights, offering practical savings in routine calibration workflows.

Where precision improves everyday operations

Ideal for calibration laboratories, quality departments and precision workshops, the set supports tasks such as routine verification, instrument adjustment and reference checks. With a compact nominal range and E1 conformity, the masses help narrow measurement uncertainty and speed up verification cycles, enabling faster decision-making and fewer repeat calibrations. The reputable KERN manufacture and the set’s durable finish combine to provide operational confidence, so measurement routines integrate smoothly into quality assurance procedures without disrupting production throughput.
