Description
The test weight KERN 346-88 is a single OIML class M1 calibration weight with a nominal mass of 20 kg presented in solid block form. Manufactured from painted malleable cast iron, it provides a durable reference standard for the verification and adjustment of balances and non-automatic weighing instruments in laboratory, industrial and metrology environments. The lacquered surface protects the cast body during repeated handling while the block geometry ensures stable placement on weighing platforms. Supplied as one piece, this individual weight belongs to the established test-weight range from manufacturer Kern and meets M1 tolerance requirements for routine quality-control and calibration tasks. Both net and gross mass are specified at 20 kg, confirming the true nominal value. Its robust construction supports consistent performance across multiple calibration cycles in production facilities, service workshops and accredited laboratories that rely on reliable mass standards of this accuracy class. The compact packaging volume further facilitates secure storage and transport of the heavy reference piece without compromising dimensional integrity.

Questions about Test Weight KERN 346-88
What is this article?
Test Weight KERN 346-88 is the article on this page. Luminix Health distributes Kern 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.
