ALCOHOL HYDROMETERS

TRALLE AND PROOF SCALES

The Tralle scale indicates directly in percent ethyl alcohol by weight in water from 0 to 100%. 

The Proof scale indicates the proof of alcohol from 0 to 200, at 60°F.

ALCOHOL, PLAIN FORM, DUAL SCALE, LENGTH 300 mm
CAT.# TRALLE SCALE DIV. PROOF SCALE DIV.
2510 0 to 100% 1% 0 to 200% 2%

 

ALCOHOL, COMBINED FORM, DUAL SCALE, LENGTH 300 mm, THERMOMETER IN BODY, RANGE -10 TO 100°F
CAT.# TRALLE SCALE DIV. PROOF SCALE DIV.
2510C 0 to 100% 1% 0 to 200% 2%
