Description
Calibration weight, 20 mg, OIML F1, NVLAP Cert is a single OIML individual calibration weight intended for accurate balance checking and metrological reference work. Conforming to OIML class F1 tolerances and provided with NVLAP certification, it enables laboratories to maintain documented measurement confidence in analytical, QC and research settings. The nominal mass is 20 mg, supplied as one piece; listed dimensions are 6,25 mm width, 3,35 mm height and 5,66 mm depth, with a net mass of 0,02 kg. Surfaces are finished to meet or exceed OIML R 111 and present a high-gloss, mirror-like polish so that scratches or contamination remain clearly visible, supporting careful handling and durability. Such individual calibration weights address professional needs across the OIML E1, E2, F1 and F2 tolerance framework where class F1 performance is specified. Delivery in high-quality protective cases keeps the weight secure, clean and free from dust, safeguarding surface integrity and long-term usability. Available from manufacturer Ohaus within the OIML Individual Calibration Weights range, this 20 mg reference piece fits routine calibration benches and accredited laboratory programmes.

Questions about Weight 1P OIML 20mg CLF1 Accrd TR
What is this article?
Weight 1P OIML 20mg CLF1 Accrd TR 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.
