How To Choose The Best Rain Gauge?
When it comes to rain gauges, there are two main types to choose – manual rain gauges and digital rain gauges.
- Manual Rain Gauges
- The first type is currently the most popular used as it’s affordable, easy to install, and use. Depending on the price point, it could be made of cheap plastic, glass, acrylic, or polycarbonate thermoplastic. Therein, polycarbonate is our favorite go-to because it’s long-lasting and more durable than glass.
- If you’re a beginner, we highly recommend using this type.
- But remember to consider carefully the capacity (amount of rainfall it can collect), ease of set up, materials, and ease of reading.
- The background should be a dark color while the numbers should be white. Pay attention to the size of numbers and measurements displayed as well if you also want to read it from a distance.
- Digital Rain Gauges
- Digital rain gauges, on the contrary, are commonly for tech-savvy people who prefer tracking the watering amount/rainfall volume indoors from a small display screen or your smartphone.
- But the biggest benefit of this rain gauge type is its in-depth information output. You’ll receive not just the volume of daily rainfall but also reports of weekly, monthly, and even yearly rainfall volume.
- Some models even provide you with other information pieces, such as calendar, outdoor/indoor temperature, indoor humidity, and settings depending on the price range and brands.
- About the flaws, there are two big ones – high price ranges and a bit more complicated to set up.
- If you want to go for this type of rain gauges, pay attention to three things: your budget, your needs, and the transmission range. Besides, consider the screen display and number size that are comfortable for you to read.
An obvious rule of thumb is the more accurate the rain gauge, the better to track the rainfall volume. If you’re a gardener or lawn owner, this is a key element to your plan in watering your plants. If you’re an enthusiast backyard, it is the decisive factor in your study or research.
Normally, a good one should be from 1” to 1/100” deviation.
Which Brands Make The Best Rain Gauge?
This is a professional supplier of weather instruments. Their team includes 20 engineers and their products were tested with strict rules before shipping. Also, all of them are backed by a 1 Year Limited Warranty.
La Crosse Technology
We trust it because this is one of the most reliable multinational manufacturers of electronic products in North America. It also has a rich history, from 1985.
Manual vs. Wireless rain gauge?
It depends on your preference, budget, and needs. If you want something cheap and easy to set up or you have just started this hobby, a manual rain gauge is ideal.
But for a backyard enthusiast or tech-savvy lawn owner/gardener whose budget is on the table, we highly recommend using a wireless rain gauge. It will give you more pieces of extensive information to serve your deeper purposes of use.
How is rain measured in a rain gauge?
It is just a cylinder with a wide funnel leading to it. This funnel is calibrated so that 1/10” of rain measures 1” when it collects inside.
1” collects in the cylinder means 1” of rain has fallen.
What unit is rain measured in?
Millimeters, inches, or points (1 point = 0.01” = 0.254mm)
What are the three types of rainfall?
They are frontal, convectional, and relief rainfall.
Where to put your rain gauge?
Put it on the side of a pole, at least 2’-5’off the ground with the cylinder top a few inches above the top of the pole. Meanwhile, keep the top of the rain gauge is level.
Choosing the best rain gauge is always complex, and always involves a compromise. Our review features options that deliver different levels of performance in a variety of aspects. We hope that our ultimate guide helped you make the choice as easy as possible.
