This outdoor thermometer for attachment to the house wall scores with a timeless, classic design and a particularly low price. The degrees in the temperature range between -30 and +50 ° C are free and can therefore be easily read at a glance. The product, which is manufactured entirely in Germany, measures the temperature using colored alcohol, as the manufacturer no longer uses mercury. Nevertheless, thanks to the 2-point adjustment, it is very precise. It is best to place it in the entrance area, on the terrace or balcony.

With a pretty floral design, this one is waiting for you Garden thermometer on which is printed with a colorful flower tendril and various butterflies and birds. The plastic thermometer can be attached to walls both outside and inside, is weatherproof and, thanks to the 2-point adjustment, particularly correct. This model is also completely made in Germany and works entirely without a battery: the temperature is controlled by the Expansion of the colored alcohol indicated, which is why the thermometer is independent of any kind of power supply is.

These wooden thermometers, which come in a practical 3-pack, can be used both outdoors and indoors. So you can attach them to different places in the apartment or in the garden and thus measure the different temperatures. In the Amazon reviews, some customers complained that these thermometers indicate different degrees. This is completely normal and not an exclusion criterion, provided the temperature meters have been installed in different locations. Nowhere in a room is it equally warm. Hard and robust beech wood was used for the housing, the temperature range between -50 and +50 ° C is particularly large.

Purchase criteria

species

Mercury Thermometer / Analog Thermometer: Since mercury is highly toxic, mercury thermometers have not been allowed to be sold within the European Union since 2009. Since then, manufacturers have been using colored alcohol for analog thermometers instead of the problematic material.

(Electrical) bimetal thermometer: Bimetal thermometers, also known as dial thermometers, also work on the basis of the expansion of substances when heated. In this case, various metals connected to one another expand and thus show the temperature. Many models function entirely without electricity, while others only run on batteries or rechargeable batteries.

Digital thermometer: In contrast to analog thermometers, digital thermometers only work with electricity that either comes from the socket or (usually) is supplied by a battery or a rechargeable battery. The energy consumption is low, but batteries must be replaced or replaced regularly. Batteries are charged in good time. On the other hand, these thermometers are often very precise in their measurement.

Accuracy and temperature range

The measured temperature range should be selected as wide as possible, as it is very cold or very cold at some locations in Central Europe. can get hot - in a very sun-exposed location in the garden, temperatures can easily climb to values ​​of 40 ° C and more. The largest possible temperature range then prevents your outdoor thermometer from breaking due to overload. The accuracy of the measurement is also of great importance, although analog thermometers can of course only measure the temperature at their respective location. That is why there are often differences between different garden thermometers.

Material and weather resistance

Outdoor thermometers can be made of various materials. Often (and inexpensively) models made of plastic are offered, but wood, metal, glass or ceramics can also be used. It is important that the material of a thermometer used outdoors is weatherproof, i. H. is not affected by the influences of light, wind, rain, heat and cold. In addition, the material must not interfere with the temperature measurement, for example because the metal becomes very hot.

Structure, function and assembly

Analog thermometers are so popular to this day because they are simple and easy to use and how they work are uncomplicated: you put them on a wall (with a little distance to it!) and read the result then off. So that reading is not too laborious and can be done with a glance at the thermometer, the degrees should be written as clearly and capitalized as possible. Instead of hanging, you can also opt for a model that can be set up, for example on a table or on the windowsill. Some outdoor thermometers can also be stuck into the earth on a long stick at the desired location.

Additional functions

Analog outdoor thermometers do not have any real additional functions, but you can combine or use them with a hygrometer and a barometer. buy a combination device straight away. The hygrometer measures the humidity, the barometer the air pressure.

frequently asked Questions

What is an outdoor thermometer?

An outdoor thermometer is an analog or digital device for measuring the temperature in the Outside, for example in the garden, in the entrance area of ​​the house, on the terrace or on the Balcony. Outdoor thermometers must be weatherproof and not necessarily be placed in a blazingly sunny location.

How does an outdoor thermometer work?

Analog thermometers work because liquids (and other substances, e.g. B. Metals) expand when it is warm and contract again when it is cold. Since mercury in the past and alcohol today only at extremely high resp. Boiling or freezing at low temperatures are ideal for mapping Central European temperatures. Digital thermometers have a temperature sensor that measures the outside temperature and transmits it to the device.

What is the difference between an outdoor thermometer and a weather station?

While with an outdoor thermometer you only have to measure the temperature or, if you have decided on a combination device, also Being able to read humidity and / or air pressure, a digital weather station gives a closer look at the current and that expected weather. With a weather station, you place one or more sensors outside, which then send their measurements to the display, which is often placed inside.

Where is the best place to attach the outdoor thermometer?

You should choose the right location so that the new outdoor thermometer also measures the correct temperature. It is particularly important that the thermometer is not directly illuminated by the sun, as this greatly falsifies the temperature measurement. Instead, look for a shady, not too shady place that also protects the device from wind and weather.

What alternatives to the outdoor thermometer are there?

Instead of an analog outdoor thermometer, you can also opt for a digital weather station. This is a multi-part device, which consists of a display (usually to be set up indoors) and a or consists of several sensors. You can install these temperature sensors in strategically clever places outdoors. Weather apps on the cell phone can also be an alternative, but they do not give the specific temperature in your garden or on your balcony.

Which manufacturers of outdoor thermometers are particularly recommended?

One of the leading manufacturers of outdoor thermometers is the manufacturer TFA Dostmann, based in Wertheim in the Taubertal, who all produce their products in Germany. Lantelme has also been in the business for over 30 years and supplies high-quality thermometers for indoor and outdoor use. Pearl and GardenMate also offer good quality in this area.

Weather station

If you not only want to find out the temperature in the garden, but also values ​​such as humidity, wind strength and weather tendency, then a weather station is the right choice. With one you don't have to walk into the garden to take a look at the thermometer - you can set up the weather station at any desired location.
