ASTM Equivalent Non-Mercury Thermometers

These liquid-in-glass thermometers have physical and performance characteristics identical to ASTM thermometers for their referenced applications but have not yet been reviewed and accepted by ASTM for these purposes. They use a safe blue indicating liquid that is biodegradable, non-toxic, and non-hazardous. The dark blue color of the indicating fluid is easily read against the white-backed stem.

ASTM Equivalent Non-Mercury Thermometers

A “T” suffix on model numbers indicates thermometers with five-point certification by an ISO/IEC accredited laboratory. Always store Non-Mercury Thermometers vertically with a Thermometer Storage Rack to prevent indicator fluid separation.

Select the desired temperature range and divisions from the product filter to narrow your choices.
