Description
The OIML class M2 test weight of 20 g is a single individual weight featuring a practical knob shape and manufactured from finely turned stainless steel in accordance with OIML requirements. This precision reference mass enables reliable verification and routine checking of laboratory balances and scales. With its nominal value of 20 g and M2 accuracy class, the weight is well suited for general laboratory and industrial weighing tasks that demand consistent mass standards. Supplied as 1 pc, the compact knob design allows secure handling and easy placement on weighing pans during calibration procedures. The piece is produced by manufacturer Kern and follows the finely turned stainless steel construction specified for OIML-compliant single weights. Stainless steel material provides durability and stability for repeated use in controlled environments. Such test weights support quality assurance workflows by helping maintain measurement integrity and traceability of weighing instruments. The straightforward form factor integrates smoothly into daily laboratory routines for mass determination and instrument performance monitoring across scientific and technical applications.

Questions about Test Weight KERN 357-05
What is this article?
Test Weight KERN 357-05 is the article on this page. Luminix Health distributes Kern 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.
