A professional who tests pulverized material and computes specific gravity, using manometer tube. Respnsibilities include:

• Collects mill samples, weighs specified amount of pulverized material, and pours it into cylinder and taps powder into compact mass.
• Raises mercury level in left side of manometer tube by pumping air into right side, using hand pump.
• Inserts cylinder of pulverized material into top of left tube.
• Releases air pressure from right side and times drop of mercury level in left side, using stopwatch.
• Computes specific surface of material, using standard algebraic formula.
• Reports below-standard reading to mill operator.
• May test milled sample of aluminum alloy to identify metals in sample and be designated Quantometer Operator.
