Geratherm - Model Classic -Glass Thermometers
The Glass thermometers have a far-reaching tradition and analog thermometers have long been the method of choice for measuring body temperature. However, glass thermometers still offer some decisive advantages today. Due to the closed glass body, the thermometer can be disinfected as a whole and is ideal for allergy sufferers. And our thermometers have long since stopped containing toxic mercury. Today Galinstan is used as the measuring liquid. We believe in a tradition that goes back more than 100 years and are convinced that it is still an environmentally friendly, reliable and, above all, durable variant of digital thermometers.
- Sustainability
We produce our thermometer exclusively (95%) with raw materials from Germany. Properly stored, it accompanies you for a lifetime.
- Suitable for allergy sufferers
This thermometer is particularly suitable for allergy sufferers. The closed glass body is free of metals or plastics. It can also be cleaned and disinfected 100% safely.
- 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.
- 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.
Our thermometer is real manual work and each of the 25 work steps is subject to strict quality control. Each thermometer is calibrated, which guarantees measurement accuracy. That is why there is a small line mark on every thermometer, after which the scale is fitted. This has an impact on how the scale looks, whether more or less white space or 35 °C is specified or not.
The different scales and the line mark are not a quality defect, but are due to the manual production and the uniqueness of each thermometer.
The measuring liquid must be reset before each new measurement. You can do this in no time with the included "easy flip" shaking aid. Place the thermometer in the device and grasp the upper end of the shaking aid between your thumb and forefinger. Now all you have to do is make the easy flip vibrate.
