Shopping guide

Rain gauges are essential whether you work in the field of meteorology, or if you are an enthusiast of gardening and urban orchards, as they offer accurate data on rainfall in your area. However, there are many options on the market today, so we have prepared this guide to buy the best rain gauge, so that you can choose the one that best suits your requirements.


When making a comparison of rain gauges, it is necessary to first define the type of instrument you need. They can be classified into two large groups, the analog ones, which have a classic funnel- or cylindrical-type design, and the electronic or digital ones, which are generally connected to a base station.

The analog rain gauge is a transparent container, which brings a scale to the naked eye for greater practicality. In this sense, it is enough to observe the accumulated water to obtain the data. Also, it is good to mention that it is usually an economical device if we take into account its functionality.

For their part, digital rain gauges are usually made up of two parts and are battery-powered, so they need to be replaced periodically. In these models, one of the pieces is a container that works as an external sensor, to send data via wireless connection. The other piece is the base station, which receives the data and has various functions depending on the model you choose.

It is important to mention that electronic rain gauges are very useful for meteorology enthusiasts and even for professionals, as they display and store a large amount of information on rainfall. In some cases, the data can be sent to mobile devices such as smartphones or tablets, which is very convenient and practical.


The design of a rain gauge responds to the type of instrument, in this sense, analog models often need a support that is fixed to the ground, to prevent strong winds from knocking the device down. However, the number of included plugins can influence how much the product costs, so it is good to check this feature before making the purchase, since in some cases you have to purchase the support separately.

On the other hand, it is important to take into account the material from which the rain gauge is made, since the most flexible ones, such as polypropylene and polystyrene, can resist weather conditions, while glass is usually more fragile. Digital rain gauges are usually made of very strong plastics, however base station displays can be delicate so care is important to extend their lifespan.

Regarding the measurements of the rain gauge, we must make sure that the upper opening has a good diameter, so that the instrument can collect as much water as possible. However, it is worth mentioning at this point that most rain gauges are compact and lightweight, so they can be easily moved from one place to another.


Each rain gauge has specific functions that we must take into account. In general, the analog one is quite practical to use, so that by making a visual reading of the amount of water, the level of precipitation is determined over a period of time, thus fulfilling its main objective. 

On the other hand, digital rain gauges have various functions, such as recording the amount of rain for the day, week, month, and year. Also, there are models that offer graphs with the data to get an idea of ​​​​the values ​​​​over a period of time, in this sense, they can have a more professional use. 

Also, there are other rain gauges with the rain alert function, which are capable of indicating when rainfall begins, so they allow us to adapt our activities based on the weather. In addition, they offer temperature values ​​in °C and °F.

If you need to keep an eye on rainfall in real time, then you can opt for a rain gauge that has the function to connect to other smart devices such as phones and tablets. Similarly, these models can offer compatibility with various operating systems and some work with the Alexa virtual assistant, so they are very functional. On the other hand, we mentioned that if you do not have mobile devices, you can review the data on a computer.

Frequently asked questions

Q1: How to make a rain gauge?

Making a rain gauge can be very easy, so if you want to make it experimentally, all you need is a clear bottle, scissors, a ruler, a permanent marker, small rocks, and a measuring cup to measure the volume of water. The first thing is to make a cut in the bottle at 2/3 of the length measured from its base. Then, you have to place the stones inside the container and add water to cover them, in this way, the level that marks will be the zero of the scale.

Next, we must identify it with the permanent marker. However, it is necessary to fit the other part of the funnel-shaped bottle, in this way, evaporation is avoided. Later, with the graduated glass, you have to pour a specific amount of water into the bottle, for example, 20 milliliters, and with the marker draw the corresponding line, to refill the glass, repeating the process until completing 300 milliliters, of so that the scale of the rain gauge can be obtained. 

Once you have the scale, you must know the equivalence in liters per square meter or millimeters, which is the measure in which rainfall is expressed; in this sense, you must know the diameter of the opening of the rain gauge to calculate the surface of the circle. Finally, you have to divide the amount of water in ml that the rain gauge stored by the surface of the circle, in order to obtain the precipitation value expressed in milliliters per square centimeter, then it is possible to convert the result to liters per square meter.

Q2: What is a rain gauge for?

The pluviometer is an instrument used to measure the amount of water that falls in precipitation, at a specific time and in a certain location. In this sense, it is essential for meteorology, which is why it is used in agriculture and gardening to obtain rainfall data. In this way, it is possible to correctly dose the irrigation of crops and plants.

Q3: How does the rain gauge work?

In the analog rain gauge, the water enters through an upper opening and is stored in the container. In this case, it is possible to make a visual reading of the amount of water that has fallen, thanks to the fact that the collector has a graduated rule. For its part, the digital rain gauge has a rocker inside that moves from one side to the other with the weight of the water deposited. This movement causes a magnetic sensor to activate and send the signal to the built-in battery-powered circuit. In this sense, the signal is sent by radio frequency, from the circuit to the base station, which in turn transforms the data into mm of water.

Q4: Who invented the rain gauge?

The rain gauge was invented by the Korean scientist Yang Yeong-sil in the year 1441, however, the Greeks 500 years a. C. made the first measurements of rainfall. Many years later, in India they measured the rain in buckets.

Similarly, in 1636 Benedetto Castelli made the first measurements of precipitation in Europe. Later, in the year 1662, the Englishman Christopher Wren invented the first tipping bucket rain gauge and by the year 1670 the rain gauges improved in design while maintaining the basic principles that we know today.
