Description
OIML weight set 500 mg–1 mg Class F2 No Certificate TR is a precision calibration weight set for laboratory and metrology use covering the nominal range from 500 mg down to 1 mg. Weights from 1 g to 1 kg are produced from Troemner Alloy 8 stainless steel that offers a strictly controlled density of 8,03 g/cm³ together with extremely low magnetic properties, high stability and strong corrosion resistance. All weight surfaces meet or exceed OIML R 111 and receive a high-gloss polished, mirror-smooth finish that readily reveals scratches or foreign particles while supporting long-term durability. The complete adjusted set is delivered in a high-quality protective case that keeps every piece secure, clean and dust-free, thereby protecting the investment. This Class F2 configuration from manufacturer Ohaus meets or exceeds the applicable OIML tolerance requirements for classes E1, E2, F1 and F2. It is intended for routine calibration, verification and quality-control weighing tasks where Class F2 accuracy without certificate is specified. Net weight of the set is 0,00111 kg.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Set OIML 500mg-1mg CLF2 NoCert TR
What is this article?
Weight Set OIML 500mg-1mg CLF2 NoCert 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.
Which category should I open next?
The category is Balances & scales. The sub-category is Calibration & test weights. The catalogue is Lab instruments.
