Precision Weight (Mass) Standards

The weight tolerance is equal to ANSI/ASTM E617 Class 0 and exceeds OIML R 111 Class E2. This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical

Perfectly Designed for any kind of Balance Testing ASTM precision weights, Best Price-Performance Ratio Low magnetic permeability and high corrosion resistance ensure reliable values. All weights are made with stainless steel, no aluminum is used

Analysis Note Assay (GC, area%): &#8805 99.0 % (a/a) 2-Naphthol (GC, area%): &#8804 0.

1/4 Retardation Plate

The weight tolerance is equal to ANSI/ASTM E617 Class 0 and exceeds OIML R 111 Class E2. This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical

Screw knob style weights are ideal for most laboratory calibration applications Sizes from 1 mg to 100 g Two-piece polished stainless steel gram weights Five tolerance levels from Ultra Class SM to ASTM Class 4 Sets and individual weights available

To get all the accuracy your electronic balance and/or scale provides, you need to perform routine calibrations and verifications using precision calibration weights. Troemner&#39s Stainless Steel Electronic Balance Calibration Weights are intended
