ASTM Non-Mercury Thermometers

ASTM Non-Mercury Thermometers meet standard test method requirements for use in their referenced applications. The liquid-in-glass thermometers have the same performance characteristics as ASTM Mercury Thermometers, but use a safe blue liquid as an alternative to mercury. The proprietary formula is biodegradable, non-toxic, and nonhazardous. The dark blue color is easily read against the white-backed stem.
