Buying guide: how to choose the best rain gauge?

The rain gauge is part of the range of measuring devices and measuring instruments including the anemometer, the barometer, or the hygrometer. It actually helps determine the amount of rain that has fallen during a downpour.
At one time, the rain gauge was confined to the fields of meteorology, rainfall and the nursery.This rainfall measuring device is currently finding its place among gardeners and farmers.We then speak of garden rain gauge and agricultural rain gauge.They are a great help in quantifying precipitation, in order to determine whether or not watering is necessary.Indeed, some plants have a specific water requirement.It is therefore better to stick to the threshold set to ensure their proper development.Finally, by respecting this "greener" watering rule, gardeners and farmers can also save considerable money.
Here are the results of our tests and comparisons on the models offered on the market. They will serve as a guide to the best rain gauge for your daily life.

Manual rain gauge

The manual (or direct reading) rain gauge is the most basic model. It is in the form of a graduated funnel, with a rather basic measuring range. A simplicity that arouses the interest of gardeners and farmers, amateurs and professionals alike.
This rainfall measuring device is also easy to use. To determine the amount dropped per square meter, simply read the level of water that has settled in the funnel. There is also a simplicity of installation: you will only have to plant the support in the ground. As a bonus, take advantage of advantageous rates. You can afford a manual rain gauge for less than 10 euros.

Automatic rain gauge

In many ways, an automatic rain gauge is more practical than a manual rain gauge. You will effectively save yourself the tedious task of reading the water level on the tank, or even emptying it before a new measurement.
There are two types of automatic rain gauges, namely standard models and non-standard models.
The so-called "normalized" rain gauge is found in meteorological stations in France. It consists of two buckets looking in opposite directions. In practice, one of them collects the rainwater and once full, it self-empties, leaving its place for the other bucket. The measurement is therefore made by multiplying the total volume of the buckets by the number of empties. On some models, this latter element is clearly displayed on an LCD screen or electronic display.
The non-standardized rain gauge uses an electronic gauge to quantify precipitation during a specific period.Depending on the model, it thus has a more or less significant measurement range.During a measurement session, the non-standard rain gauge transmits in real time to a weather station located inside.A practical aspect that arouses the interest of gardeners or farmers using an automatic watering system.Finally, the non-standardized rain gauge is available in models powered by a battery, solar energy, or even with measuring devices such as a weather station.

Our tests and comparisons have enabled us to highlight the main advantages of the electronic rain gauge.

Extremely precise

An electronic rain gauge is extremely precise, and therefore reliable. Its principle is based on the bucket system. Equipped with a transmitter and an electronic pulse or ultrasonic wave transmitter, the latter sends signals to the weather station at each automatic emptying.
For more details in the calculations, some electronic rain gauge models are also equipped with a whole set of sensors. Indeed, the operation takes into account various parameters such as atmospheric pressure, wind speed, wind direction, relative humidity, evaporation rate, and air quality.
This precision explains the enthusiasm of gardeners for the electronic rain gauge. By reading the data on the LCD screen, they can know the right time to water, but also the amount of water required.

Temperature measurement

The usefulness of an electronic rain gauge is far from being confined to the sole domain of calculating precipitation. Indeed, it can also act as a weather station in its own right. Thanks to its temperature sensor, you can also know with precision the interior temperature and the exterior temperature. Data that reveal all their usefulness for gardeners who grow in greenhouses.


Some models of electronic rain gauge are associated with a wireless weather station, which allows you indoor and outdoor use. They're tough enough to withstand the elements, even when the hail is on the party.
