ASTM calibration weights set (1 mg-200 g) cylindrical shape
Detail Product Description
All weights are made of premium stainless steel to make them corrosion resistant.
Monobloc weights are specially designed for long term stability, and weights with an adjusting cavity provide best value for money.
Electrolytic polishing ensures glossy surfaces for anti adhesion effects.
ASTM weights 1 kg -5kg sets are supplied in attractive, durable, high quality, patented aluminium box with protective polyethylene foam and
ASTM weights cylindrical shape are adjusted to meet class 0, class 1, class 2, class 3, class 4, class 5, class 6, class 7.
Aluminium box designed in an excellent protective way with bumpers by which the weights will be protected in a firm way.

Processing
For high class SS it goes though mirroring and mechanical polishing
And for chrome plated or titanium plated after shaping it we elcetrically coat it with chrome
Application
ASTM weights can be used as reference standard in calibrating other weights and appropriate for calibrating high-precision analytical and high-precision toploading balances, laboratory students, and rough industrial weighing.
Advantage
With more than ten years of experience combined with special skill acquired through years of weight polishing guarantee the consistent high quality for all customer demands.
ASTM weights are designed to resist dust offering a long term stability.
