acidometer

Example Sentences

• "If it shows by the reading of the acidometer, which is left to float in the electrolyte, that its specific gravity has increased from 1,150°, its density when first poured in, to 1,210 or 1,220 toward the end of the estimated number of hours of charging, then it may be taken for granted that charging has been continued as long as necessary."
• "The strength of the acid can be determined by the use of an acidometer and a glass cylinder. The acidometer is placed in the cylinder and sufficient acid at 60°F. is then added to make the acidometer float."
