Description
Weight Set (25), 1 kg-1 mg, OIML E1 is a precision OIML calibration weight set intended for high-accuracy mass determination and balance verification in laboratory and metrology applications. As an OIML Class E1 product it offers high accuracy, low tolerances and a guaranteed uncertainty equal to one-third of the tolerance. All weight surfaces fulfil or surpass OIML R 111 requirements and receive a mirror-smooth high-gloss polished finish. Weights ranging from 1 g to 20 kg are manufactured from Troemner Alloy 8 stainless steel, which provides a tightly controlled density of 8,03 g/cm³, extremely low magnetic susceptibility, reliable stability and good corrosion resistance. The set comprises 25 pieces spanning 1 kg to 1 mg and is delivered in a premium protective case that maintains the weights in a safe, clean and dust-free condition, safeguarding the user’s investment. Produced by Ohaus, these adjusted weights meet or exceed the tolerance limits specified for OIML Classes E1, E2, F1 and F2. Net weight of the complete set is 2,11 kg, making it well suited to rigorous calibration tasks in analytical and industrial laboratories.

Questions about Weight Set OIML 1kg-1mg CLE1 NoCert TR
What is this article?
Weight Set OIML 1kg-1mg CLE1 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?
