Description
Calibration weight 1 kg OIML class M3 is an individual scale calibration weight intended for verification and routine checking of balances and weighing instruments. This certified reference mass belongs to the OIML M3 accuracy class and is manufactured from stainless steel. Weights from 1 g to 10 kg are produced in stainless steel and supplied in a protective case that shields the surface during handling and storage. The nominal value of 1 kg makes the piece suitable for everyday calibration tasks in laboratories, quality-control departments and industrial weighing stations. Produced by Ohaus, the weight offers a robust construction suited to regular metrological use. Both gross and net weight are given as 1,177 kg. Originating from Switzerland, the product supports standard calibration workflows where an M3-class weight is specified. It functions purely as a physical reference mass without display devices. The protective housing helps preserve surface integrity and calibration stability over repeated handling cycles. Supplied as a single piece, this calibration weight integrates readily into established OIML-based quality systems for scale verification.

Questions about Weight, 1kg, OIML M3, OH, CERT
What is this article?
Weight, 1kg, OIML M3, OH, CERT is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Instruments de laboratoire.
A test weight is a mass of a stated class, used to check a balance. The class sets the tolerance. A weight that is dirty, or that has been handled with bare fingers, is no longer that class. The certificate ties the weight to a standard.
A balance compares a mass with a standard. An analytical balance reads to 0.1 mg or finer and needs a draft shield and a stable bench. A precision balance is coarser and faster. A platform scale takes a heavier load. The reading is only as good as the calibration chain back to the kilogram, which is why test weights and a certificate exist. A moisture analyser is a balance with a heater: it records the loss of mass as water leaves. The unit of mass is kept by the BIPM, compared across Europe by EURAMET, and accredited by BELAC. NIST publishes the same measurement foundations.
