4-in-1 SOIL METER (Green)
4-in-1 SOIL METER (Breen)
Free Plant Growing Guide & Free Sandpaper
4-in-1 Multi-Function: This hygrometer can meet your needs to measure soil moisture, Ph, nutrients, and light conditions at the same time. Cost-effective, compared with the traditional single-function soil tester, you only need to buy one, and you can enjoy four services. It can help you gain a complete understanding of your plants
Single-probe Design: The single-probe with upgraded material. Compared to traditional dual probes, a single probe can reduce damage to plant roots when inserted into the soil and is a reliable Plant Care Tool
Fast Response: You only need to insert the probe deeper than 4 inches into the soil and get test results in seconds (must be greater than 4 inches deep)
Patented Design US No.D968976: The patented design of the 90° rotating head allows you to read the dial without bending down and looking down. You can bend the head 1°-90° at will. Adjust to the angle that best suits your reading
No Batteries Required: easy to store. Great for Garden, Lawn, Farm, Indoor & Outdoor Use. If the tester doesn’t work, try sanding the tip and pole
Customers say
Customers find the humidity meter easy to use and read. It provides useful information about soil nutrients and pH levels. Many consider it a good value for the money. However, some have mixed opinions on its functionality, moisture level, measurement accuracy, and build quality.

Works Well for My Purposes
I have a small container garden on my deck that I thoroughly enjoy, but sometimes a plant or two will go belly-up for some reason unbeknownst to me 🤔😣. Over-watering…under-watering? Not enough sun…too much sun?So, I’m trying to deliver to my “plant-children” what they need to thrive! This is a very useful tool that has proven highly reactive in all categories it is designed to assist in monitoring….proper soil moisture seems the most critical in my experience…(along with monitoring for plants being root-bound, and pests 👀) … Simple to use, I try to poke it in the same hole to prevent from injuring the root system. I always wipe the soil from the probe tip and place it back in the box it came it and handle carefully to avoid damaging it. It does come with a small postage stamp sized piece of fine-grit sand paper incase mineral scale develops. The pH scale on the probe need only go from 3 to 10 as this is the range typically seen in yards and potting soils; anything more alkaline is highly unlikely and generally wouldn’t support plant life very long…I mean you’re not testing liquids in a laboratory for Pete’s sake…so it doesn’t matter nor is it necessary to have the full pH scale available 🙄😒😆.I definitely can recommend this soil monitoring probe! Very useful! Thank you!

Good soil tester
The Raintrip soul tester is durable, accurate and relatively easy to use. This meter reads light, moisture, nutrients, and pH in the soil allowing you to keep your plants healthy and happy. The display is clear and easy to read and the head swivels so it is easy to get an accurate reading on any size plant from any angle. The slide button on the front is a little hard to see which mode you are in, light, moisture etc. so that’s why I only give it 4 stars. Other than that it is an all around good soil tester.

Updated 2024 – pH readings wrong / Good Customer Service
UPDATE: The pH metering stopping giving me readings. I used in the Fall and it stopped working in Spring. I sanded it per instructions but didn’t help. Customer service quickly got back to me and sent a replacement with some extra hints.I think I might have messed it up because you are only supposed to lightly sand the lowest piece of the probe – the tip – but I had lightly sanded the length of the probe. The extra instructions they sent said this – so save your sandpaper and don’t overdo it like me and you should be able to enjoy using it for multiple seasons.—-The meter does produce different results for different soils around the yard. I mainly wanted the pH part, the other stuff isn’t super necessary for my needs but interesting nonetheless. The pH seems like it could be pretty correct as it does adjust slightly for soils I know are more acidic (due to the type of fertilizers I use.) My problem is that the range of pH anyone really needs for soil is liberally only between 4.5 – 8.5. If you have soil below or above these it really doesn’t matter how much since it is so far off the chart of what is needed for anything other than highly specialized growing media. And if you were doing that you would have more sophisticated equipment.So the entire range of what I care about takes up very little space between 1 and 8 since everything I have is between 5.5 and 7.0 pH. It’s impossible to see at this scale if you are at 5.8 or 6.2 or what. You just have a rough approximation that it is about 6 which isn’t super helpful. Every 0.1 change in pH represents a 26% difference in acidity or alkalinity of the soil. This instrument should be fine tuned for a smaller range of the pH scale showing at least .5 unit steps.An annoyance is that the needle at rest, in no soil medium, is pretty much right over the 6.5/7 pH scale. So if you insert the probe into soil that is 6.5 the needle doesn’t move causing you to think it doesn’t work. Every time this happened to me I flipped the switch around and would see the needle react very quickly and so I know it was functioning but the resting needle should really have its own place as is the standard on almost every other instrument you can find.The probe itself seems well constructed. I pushed it deep into the ground and was able to pull it out pretty easily. I think if you put too much pressure on the meter head while pushing it in you might break it though. The box comes with a little square of sand paper you should not throw away. Eventually the probe will lose its measuring abilities from a little corrosion build up on the metal. A light sanding would refresh it.

Good tester
Works well

Works as advertized
Good deal for the price on comparable moisture reading devises. I like the fact that the head swivels so it makes it easy to read without having to bend over if your using it on something low to the ground and having to get on your knees to read the dial from the side. It’s a little difficult to tell which setting you are on since the switch does not have a lot of movement when switching from one setting to the other and its a little hard to tell from the markings exactly what position you are on. But I just put the switch all the way over to one side and count the clicks as I move it. I would recommend.

Know when you need to water or fertilize
The soil tester is easy to use and clean, and provides a lot of information. The long stem allows me to check moisture and nutrition content at the important depths (1”, 3”, and 5”).You will want to look at the switch settings before putting it in the ground as they are difficult to read and align.Buy if you want to know if you need to fertilize or avoid over/under watering your flowers, plants, or vegetables

Just ok
I have not found this product to be accurate especially for moisture. I was hoping to avoid over watering and under watering my plant by using this meter as well as keeping the pH in check. But from the appearance of the plant, it is not working. Even after watering, the meter shoes the plant in the dry zone. Though the plant was a gift and started out healthy, I will allow for the possibility that it could be just the plant itself that is the problem. I do like that the meter head tilts making it easier to read.

Great tool saved many plants from expiring.
The function indicator is difficult to read, so pay attention to it. Beyond that, the meter performance is excellent!
Lynne –
Easy to use, no batteries to replace. Head tilts for easy reading.Arrived on time, securely packaged, and in excellent condition.

China scam product, does not work.
Double B –
It works well. The dial is a little hard to read for me as the numbers are small and my eyesight isn’t what it once was. Other than that, I’m very happy with the product.
Amazon Customer –
Reading for pH is very approximate. Could be used as a toy for smart kids.

I might received a defective item. All the testings shows far left values. I have tested different soils and plants.
