Accuris™ calibration weights are ideal for calibration of your Accuris lab balance (or any brand). Three single weights are available, 100g, 200g, and 500g, and a full weight set has recently been introduced. All weights meet class F1 tolerance per OIML (International Organization of Legal Metrology) Recommendation R111 and are made of highly polished, non-magnetic stainless steel.
Special tweezers, with non-scratching plastic points are also available for proper handling; precision weights should not be touched with bare hands as oils and salts from the skin can stick to the surface of the weights.
The W1000 series of individual weights come in protective plastic cases with a screw top cover. The W1100-200 Weight Set includes 23 weights ranging from 1mg to 200g and is packaged in a protective carrying case with a set of tweezers, a dust brush and cleaning cloth.
