Twaddle Hydrometer
The Twaddle scale is a simplified scale based on specific gravity where 0° Twaddle equates to SG60/60°F of 1.00 (that of water) and each degree of Twaddle equals 0.005° SG. Our range of Twaddle hydrometers are available in 2 lengths, 160mm or 300mm, each with single degree divisions, and are adjusted for use at 15.6°C (60°F) for medium surface tension liquids.
Baume hydrometers are for liquids heavier than water. Zero degrees Baume equates to an SG 60/60°F of 1.00. The Baume of distilled water is 0. This scale uses the accepted relationship for degrees Baume where: Liquids heavier than water SG= 145/(145-°Be).
So the correct option is(a).
