INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780284)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780284)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780284) is a high-precision calibration weight designed for accurate verification and calibration of analytical balances and microbalances. Manufactured in accordance with OIML Class E2 standards, this weight provides reliable accuracy and stability for laboratories that require precise mass reference without the extreme requirements of E1 class weights.

This 1 mg weight features a flat design and one-piece construction, ensuring excellent mechanical stability and reduced uncertainty during handling and calibration procedures. Made from 3003-H14 aluminum, the weight offers consistent density and resistance to deformation at very low mass values. Each unit is supplied with a protective storage case, helping to prevent contamination, oxidation, and physical damage when not in use.
