Description
5 kg OIML M1 calibration weight is an individual scale calibration weight for verifying and adjusting balances and scales in laboratory, industrial and quality-control settings. It belongs to the OIML Individual Scale Calibration Weights product type and is specified to OIML accuracy class M1, making it suitable for routine metrological checks and instrument verification workflows. This weight type is manufactured from aluminium, copper, nickel-plated copper or stainless steel and is supplied in an individual protective case that helps shield the surface during storage and handling. Scientific data list a nominal mass of 5 kg together with a net weight of 5,214 kg and a gross weight of 5,214 kg; the unit is offered as a single piece without integrated display devices. Available from manufacturer Ohaus, the weight supports calibration laboratories and production environments that rely on standardised class M1 test masses for periodic balance and scale verification. Its protective packaging and defined OIML classification facilitate organised storage and repeated use in controlled weighing applications where traceable mass standards are required.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 5kg, OIML M1, OH
What is this article?
Weight, 5kg, OIML M1, OH is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Lab instruments.
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.
