PerformaTherm™ Non-Mercury Thermometers
PerformaTherm™ non-mercury thermometers have precise tolerances, low uncertainty, and quick response time, just like mercury instruments. PeformaTherm’s STB blue liquid is safer than both mercury and most traditional spirit thermo-meter liquids. The proprietary formula is biodegradable, nontoxic, noncaustic, and nonhazardous. The dark blue liquid is easily read against our white-backed stem for additional assurance against errors. PeformaTherm meets all ASTM standards for accuracy, tolerance and uncertainty. Manufactured for use at 76mm immersion.
