Description
Block weight M1 1000 kg is a heavy-capacity single test weight for calibration and verification of industrial and laboratory scales. This M1-class individual weight is made from grey cast iron and finished with a durable black paint coating that protects the surface during routine handling. With a nominal mass of 1000 kg it sits at the upper end of the M1 single-weight range from 100 kg to 1000 kg, making it suitable for checking high-capacity balances, platform scales and related weighing systems. The solid cast construction provides the mechanical stability required for repeated use as a reference mass in metrology and quality-assurance environments. Offered by manufacturer Sartorius as a single piece, the block weight has a net weight of 1000 kg and supports performance checks wherever an M1 grey-cast-iron reference mass of this capacity is specified. Service laboratories, industrial calibration teams and quality departments can deploy it for adjustment procedures and routine verification workflows that demand a robust, clearly defined test weight.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Block weight, 1000kg, M1, handle
What is this article?
Block weight, 1000kg, 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?
