Description
1 kg OIML M1 calibration weight is an individual scale calibration weight intended for precise verification and adjustment of balances and industrial weighing instruments. Built to OIML M1 accuracy class, it serves as a dependable reference mass for calibration routines, performance checks and quality-control applications. The weight is manufactured from aluminium, copper, nickel-plated copper or stainless steel and is delivered in an individual protective case that shields the surface and helps maintain calibration stability. This certified single-piece unit from manufacturer Ohaus forms part of the OIML individual scale calibration weights range and is particularly useful for higher-capacity systems. Net weight is 1,177 kg and the product originates from Switzerland. The combination of durable material options and dedicated protective packaging makes the 1 kg weight practical for both fixed laboratory stations and mobile metrology kits, ensuring reliable mass comparison whenever accurate balance testing is needed.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 1kg, OIML M1, OH, CERT
What is this article?
Weight, 1kg, 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.
