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 safe blue liquid as an alternative to mercury.

ASTM Non-Mercury Thermometers

The proprietary formula is biodegradable, nontoxic, and nonhazardous. Dark blue color is easily read against the white-backed stem.

The “T” suffix added to model numbers indicates individual Thermometers with NIST traceable five-point certification by an ISO/IEC accredited laboratory. Full sets of Certified Precision Use Thermometers are available as MA-751CT for S62C to S67C ASTM numbers, or MA-751FT for S62F to S67F. To prevent fluid column separation, always store Non-Mercury Thermometers vertically, using a storage rack.
