Description
Block weight M1, 500 kg is a large individual test weight for calibration and verification of high-capacity balances and industrial weighing systems. It is made from grey cast iron with a black lacquered finish, forming a solid block that serves as a durable mass standard in metrology and quality-control applications. The nominal net mass is 500 kg (gross weight 520 kg), within the M1 single-weight series spanning 100 kg to 1000 kg. As a standalone block rather than a stacked set, it is well suited to checking platform scales, floor scales and other heavy-duty instruments that call for an M1 reference at half-tonne capacity. The cast body and protective black coating help resist wear during repeated lifting, positioning and storage in laboratory or production environments. Provided as one piece from manufacturer Sartorius, this block weight supports routine performance testing, adjustment workflows and ongoing scale verification where a robust 500 kg individual weight is required.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Block weight, 500kg, M1, handle
What is this article?
Block weight, 500kg, M1, handle is the article on this page. Luminix Health distributes Sartorius 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?
