Ohaus ASTM Class 1 Weight Sets, Without Certificate

Can be used as a reference standard in calibrating other weights and is appropriate for calibrating high-precision analytical balances with readability as low as 0.1 mg to 0.001 mg. Weights are designed so the specifications on surface finish, markings, construction, material density, and magnetic properties become more restrictive as the weight tolerances decrease. Weight sets 500 g and below include a polycarbonate case. Weight sets where the largest weight is 1 kg and above are supplied in a tough, lightweight, rugged case, designed to protect your weight set under any shipping circumstance.
