The Geratherm® basal offers you a sustainable alternative to hormonal contraception. The fertile days and ovulation can be identified through a daily morning measurement of the body temperature and a correct documentation. It is important to measure the body temperature immediately after waking up and definitely before getting up. In contrast to the Geratherm® classic, the basal thermometer has a more precise scale, which is accurate to two decimal places.
Sustainability
The basal thermometer is made exclusively (95%) with raw materials from Germany and can be completely recycled.
Suitable for Allergy Sufferers
This thermoter is ideal for allergy sufferers. The closed glass body is free of metals or plastics. It can also be cleaned and disinfected 100% safely.
Without Batteries
The measuring principle of the thermometer is based on the thermal expansion of materials, which is why this thermometer does not need batteries. The non-toxic measuring liquid Galinstan replaces the previously known mercury.
Special Glass from Germany
We only use special glass from Germany to manufacture our thermometer. The glass tube and the internal capillary are manufactured in-house.
