Tides and tide clocks

The origin of tide clocks can be traced back to Ancient Greece. Over the centuries, different cultures have developed their own versions of tide clocks, whereby the basic idea has always remained the same: to use the movements of the tides as the basis for measuring time.
The barometer is part of the basic nautical equipment. But not every ship or boat is at sea level.
David Burch explains in detail in his guest article what needs to be considered when using a barometer at higher altitudes.

For his outstanding achievements as a navigator, he was awarded the "Institute of Navigation Superior Achievement Award".
In September 2021, the FISCHER instrument series " POLAR " was chosen as the Manufacture Product of the Year 2021. Exactly one year later, we are expanding our successful product series with the climate meter, a combination of thermometer and hair hygrometer. In the design by product designer Mark Braun, the special qualities of our precision mechanics manufacture are translated into a contemporary design. The measuring instrument stages the relevance of analog technology, which allows us to live long-lasting and reliably in harmony with the climate.

Calibrate hygrometer

The right temperature and optimum humidity ensure healthy living & working. However, creating a healthy indoor climate requires permanent monitoring of the room humidity. Therefore, the use of a hygrometer or a climate meter (combination of thermometer and hygrometer) is essential to maintain a good indoor climate. To be able to reliably monitor your indoor climate, you should regularly calibrate your measuring device.
Saunieren dient der Entspannung und fördert die Gesundheit: Die Haut wird gereinigt, Muskeln regenerieren sich und Sie stärken Ihr Immunsystem. All das setzt jedoch voraus, dass die Lufttemperatur und Luftfeuchtigkeit richtig eingestellt sind. Andernfalls könnten Herz-Kreislauf-Probleme auftreten. Erfahren Sie hier alles was Sie im Hinblick auf Luftfeuchtigkeit und Lufttemperatur beachten sollten ...

Autumn 2020 marks the 75th anniversary of the founding of our manufactory in the Erzgebirge mountains. This is a good occasion, to look at the eventful history of the company and special FISCHER products.
Reptiles are cold-blooded (ectothermic) animals. It means that their body temperature is close to the ambient temperature. Therefore they often react sensitively to unfamiliar climatic conditions. Depending on the reptile species a certain humidity and temperature in the terrarium is necessary, because many of them absorb it through their skin or lungs. Too dry air in the terrarium can therefore cause life-threatening diseases such as pneumonia. Therefore a hygrometer should be installed in the terrarium, because it shows the prevailing humidity inside. This way you are able to maintain the climatic balance for your animal at all times, which is very important for its health condition.
The barometer is used to measure the atmospheric air pressure in hPa. The atmospheric pressure can be understood as the weight of a column of air that extends from the surface of the earth to the upper layers of the atmosphere. Due to the different warming of the latitudes, the arrangement of continents and oceans as well as movement processes in the atmosphere, the distribution of the air pressure is uneven. At sea level, the global average is 1013.25 hPa. For the most part it fluctuates between 990 and 1040 hPa
Even if they are not visible, they are the first things to be noticed when entering a room: the temperature and humidity. Both factors ensure comfortable and healthy living. Likewise, you can work more concentrated and focused at your workplace if there is optimum humidity in the office. Depending on how the room is used, a healthy room climate is between 18 and 24 °C. In contrast, the ideal air humidity is 35-65%. Proper ventilation is a prerequisite for maintaining these values. A tilted window hardly helps during an eight-hour working day. It is much better to open the windows wide several times a day and, in the best case, to ventilate the rooms crossways with the doors also open. This so-called push ventilation ensures that the walls do not cool down, as is the case with tilted windows. It also prevents condensation of humidity on the walls.

Weather stations and gardening

When it gets warmer again in spring, many people move outside and into their gardens. Gardening relaxes and makes you happy when the results are visible: A small green oasis, with beautiful flowering plants, a place to relax and unwind. The weather plays an important role in gardening and its results. Especially at the beginning of the warm season, ground frost can sometimes occur at night or the weather can change spontaneously, especially in April. To protect your garden and your plants and not to be interrupted during gardening work, it is worth taking a look at a weather station. Weather stations in the garden can not only look nice, they also provide important values to assess whether watering is still necessary today or the weather will change in the near future.
