Product information "E1 Miligrammweight"

Milligram weight made of stainless steel in wire form

Standard weights of the E1 class are suitable as adjusting, test and calibration weights for precision scales (class I) and for quality assurance according to DIN EN ISO 9001ff for scales with a graduation > 1 000 000.
These weights are used for calibration and verification of class E2 weights.
They are also suitable for high-precision weighing such as comparative measurements on mass comparators.
For a weight to be considered ISO 9000ff compliant test equipment, its accuracy must be verified. This is possible with a suitable DAkkS calibration certificate, which you can order from us.

Features E1 Milligram weight:

OIML class: E1
complies with Directive R111:2004 for weights
Nominal value: 1 mg - 500 mg
Material: stainless steel

A calibration certificate must always be issued for class E weights.

Note on storing weights of classes E and F

Please note that individual weights and weight sets must be stored protected against wear or damage caused by impacts or shocks in accordance with DIN 8127-2007-11-OIML R 111-12004 (Chapter 14.2.1). This ensures that the precision and accuracy of the weights is maintained in the long term.

Due to the very precise weight class, we strongly recommend a case for this weight.
Please order this separately for individual weights.
