Description
The 200 g OIML class E1 test weight is a single precision weight in knob form manufactured from polished stainless steel for demanding calibration tasks. This high-accuracy calibration weight meets the stringent requirements of OIML class E1 for verifying and adjusting analytical and precision balances in laboratory and metrology environments. With a nominal weight of 0,2 kg, it provides reliable reference standards for quality assurance processes and routine performance checks. The polished stainless steel construction ensures excellent durability, corrosion resistance and long-term stability of the mass value under normal laboratory conditions. Supplied as an individual weight, it is ideal for both daily verification routines and formal calibrations where the highest level of accuracy is essential. This test weight from manufacturer Kern supports compliance with international weighing standards and is suitable for use in pharmaceutical, research, chemical and industrial laboratories. The compact knob design facilitates easy and secure handling with tweezers or gloves to minimise contamination risks and preserve the integrity of the surface. Packaged as 1 pc, it offers a practical and ready-to-use solution for maintaining measurement integrity across various high-precision weighing applications requiring true E1 class performance.

Questions about Test Weight KERN 307-08
What is this article?
Test Weight KERN 307-08 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.
