Calibration Weight Set 1000g Case and Tweezers by HFS M2 Class 8pcs

Description

Product Overview

The HFS Calibration Weight Set is a meticulously engineered collection of eight precision weights designed to meet the stringent requirements of M2 class calibration. Each weight is forged from high‑grade 45 steel and finished with a chrome‑plated, mirror‑polished surface that not only resists corrosion but also ensures consistent mass stability over time. The set includes a single 10 g weight, two 20 g weights, a 50 g weight, two 100 g weights, a 200 g weight, and a 500 g weight, providing a comprehensive range that covers most laboratory, industrial, and commercial calibration needs. All components are securely stored in a specially engineered plastic case featuring foam padding to protect the weights from impact and vibration during transport. The case also includes a pair of precision‑cut plastic tweezers, allowing users to handle the small weights without contaminating them with oils or debris.

Technical specifications are aligned with the M2 class tolerance standards: the 10 g weight maintains an accuracy of ±6 mg, the 20 g weights ±8 mg, the 50 g weight ±10 mg, the 100 g weights ±16 mg, the 200 g weight ±30 mg, and the 500 g weight ±80 mg. These tolerances are verified through rigorous testing procedures, ensuring that each weight performs reliably within its designated range. The compact dimensions of the case—approximately 4.88 × 3.15 × 2.64 inches—and its lightweight design (2.42 lb) make it easy to carry to field sites, on‑site inspections, or any location where precise mass verification is required.

Usage

Designed for versatility, the HFS Calibration Weight Set excels in a variety of environments. In laboratory settings, researchers rely on these weights to calibrate analytical balances, microbalances, and high‑precision digital scales, ensuring that experimental results are accurate and reproducible. In industrial applications, quality‑control engineers use the set to verify the performance of production line scales, bulk weighing systems, and packaging equipment, helping to maintain compliance with regulatory standards and reduce product variance.

Field technicians benefit from the portable case and tweezers, which allow for quick on‑site calibration of pocket scales, handheld milligram scales, and portable balance devices used in environmental monitoring, food safety inspections, and pharmaceutical audits. The robust construction of the weights also makes them suitable for educational purposes, where they serve as teaching tools for students learning about mass measurement, metrology, and the principles of calibration. Whether you are a laboratory scientist, a manufacturing engineer, a field auditor, or an educator, this set provides the confidence that your weighing instruments are performing within the required tolerance limits.

FAQ

What is the tolerance for the 100 g weight?

The 100 g weight in this set meets the M2 class tolerance of ±16 mg, providing reliable accuracy for most laboratory and industrial applications.

Can these weights be used with milligram scales?

Yes, the set is suitable for milligram scales as long as the scale’s capacity falls within the weight range provided. The high precision of the 10 g and 20 g weights makes them ideal for fine calibration tasks.

How should the weights be stored to maintain accuracy?

Store the weights in the supplied case, away from extreme temperature changes, humidity, and direct sunlight. Avoid placing heavy objects on top of the case and handle the weights with the provided tweezers to prevent oil or dirt contamination.

Is a calibration certificate included?

Yes, each weight comes with an individual calibration certificate that documents its exact mass and the tolerance it meets, complying with international metrology standards.

What is the warranty period for this product?

The HFS Calibration Weight Set is covered by a one‑year limited warranty against manufacturing defects. Should any issue arise, contact our support team for replacement or repair options.
