Description
Calibration weight 20 g, OIML M1, certified is an individual scale calibration weight intended for verification and adjustment of balances and scales in laboratory and industrial metrology. Manufactured to OIML M1 accuracy class, the 20 g nominal mass supports routine calibration work where this tolerance class is specified. The weight is produced from aluminium, copper, nickel-plated copper or stainless steel and is supplied in an individual protective case that shields the surface during storage and transport. This OIML individual scale calibration weight from manufacturer Ohaus is supplied as a single piece and carries certification for traceable use. Net weight is 0,163 kg; the article originates from Switzerland and belongs to the product type OIML Individual Scale Calibration Weights. It contains no display devices and is suited to quality-control, testing and service environments that require certified reference masses of M1 class. The protective housing helps maintain surface integrity so that the weight remains suitable for repeated calibration cycles under controlled laboratory conditions.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 20g, OIML M1, OH, CERT
What is this article?
Weight, 20g, OIML M1, 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.
