The Geratherm® mercury-free glass thermometers are the only German designed dual scale glass thermometers that function just like a standard mercury thermometer but without the dangers of mercury or the need for batteries.
The substance that replaces mercury is a non-toxic liquid alloy called Galinstan making them a safe, accurate and cost effective alternative to mercury thermometers. The Geratherm mercury-free glass thermometers have successfully completed IRB sanctioned clinical trials at Oregon Health and Science University. They are available in several versions in both retail and clinical packaging.
The Geratherm SolarTherm Thermometer is also German designed and works using small solar cells for power and NEVER needs a battery.
