Raintrip 4-In-1 Soil Tester, No Battery Required

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.

I am not sure if this is a typical issue with these analog meters, but to get correct Moisture and Nutrient levels I have to work the meter in this way:

Switch to Ph, then to Nutrients to get a good reading on nutrient level. Then switch over to Light just to switch to Moisture to get a good moisture reading. I cannot get good readings switching between Moisture and Nutrients. When I do try this, the needle will bury itself at one or the other end of the scale, and produce a false reading. Some of the printed ink for labeling the switch is wearing off from the back and forth, but the scale is easy enough to figure out.

I will be getting a different meter I think. I Did like that it came with a piece of sand paper and instructions letting you know to sand down the metal on the meter probe a bit if your meter stops working after a while. This being a new meter, I don’t think it needs a sanding, but the note was a nice gesture from the seller. 🙂

I never thought I’d say this, but my plants are thriving, and I actually know why for once! 🌱 This little moisture meter has taken all the guesswork out of watering. No more overwatering my poor succulents or treating my ferns like they’re in a desert (whoops).

It’s super simple: just stick it in the soil, and boom—instant plant feedback. My houseplants have never looked happier, and I’ve officially retired my “let’s hope for the best” watering schedule.

The best part? No batteries. Just straightforward plant science. Get this—your plants will thank you, and you can finally stop playing that fun game called, “Is my plant dead or just dramatic?” 💧🌿

My only wish is that it was a little easier to determine what my plants need. The booklet it comes with is a tad daunting and seems very geared toward the Asian continent type plants. I’m one of those who would rather have it say “Water Me” or “Give Me Fertilizer”.

I can’t speak to how accurate the “does it need food” level is. But it works great for helping novice gardeners determine if plants need water, and light level for plant placement. Many people do not like stick a finger in the dirt! Started using in my own garden to determine if drip system was watering evenly. Helped make adjustments! Easy to read, head tilts so you don’t have to bend over to read it, no batteries! Valuable for our uses.

China scam product, does not work.

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.
