KERN 315-247 — Calibration tweezers with straight plastic tips

A KERN 315-247 tweezers designed for secure, non-marking handling of small calibration weights in metrology and workshop environments.

• Straight stainless-steel tips for secure grip
• High-quality plastic tips to protect weights
• 136 mm length for precise, ergonomic handling

Secure handling for exact calibration results

For precision tasks, secure handling is essential. The instrument offers a controlled grip on calibration masses up to ≤ 5 g, compatible with classes E1–M3, which helps reduce handling errors and improves repeatability in weighing procedures. Constructed to meet the demands of metrology, the tool supports consistent measurement routines and minimises the risk of surface contact that could alter a weight’s value. By using a purpose-made tweezer rather than fingers, the chance of contamination and thermal transfer is lowered, contributing to more reliable results in daily quality checks.

Durable build with gentle contact to sensitive masses

A corrosion-resistant body delivers long service life while the high-quality plastic tips preserve delicate surfaces. The combination of stainless steel strength and soft tip protection ensures that fine calibration weights are neither scratched nor displaced during handling. The straight tip geometry provides direct visual control when picking up minute masses, and the construction requires minimal maintenance. This balance of durability and gentle contact supports both routine laboratory work and demanding workshop environments where component care matters.

Practical design to streamline laboratory and workshop workflows

Measuring 136 mm in length and weighing about 0.02 kg, the tweezers are optimised for comfortable, precise handling throughout repetitive tasks. The tool’s length offers ergonomic reach without compromising manoeuvrability at the balance pan, enabling steady placement and removal of weights during calibration cycles. Designed for integration into existing metrology workflows, the device supports standard operating procedures and helps technicians maintain efficient throughput while preserving measurement integrity.
