Specific Gravity Standard Hydrometers
Durac specific gravity hydrometers measure the density and specific gravity of petroleum products and other heavy liquids. These hydrometers are made of lead-free ballast and glass to counteract buoyancy and facilitate easy visibility. They are individually sterlised and can withstand temperatures up to 60 degrees F; ideal for food & beverage, pharmacology, chemistry, refrigeration and transportation applications. These units conform to ASTM standards and are available in API, calcium chloride, Sal Brine, alcohol proof %, density and other scales to measure in different degree temperatures with a maximum accuracy of +/- 1 per cent.
