These top quality glass thermometers meet or exceed all ANSI/ASTM E667-79 and Michigan standards.
Feature color-coded tri-tops for safety and quick identification--blue for oral and red for rectal.
Made of full-aged, heat-tempered Corning glass for strength and durability. Each thermometer is packed in a protective plastic pencil case and measures with superior accuracy and reliability from 94° to 108° F.
In addition, they feature an extra strong weld to help prevent bulb separation and to help prevent potential mecury spills.
Also includes triple distilled mercury for quick, accurate readings; a constriction chamber for a softer, easier shakedown.
Use with color-coded sheaths for a complete thermometry system.
