One thing we loved about the meter is that it had a scale of 1-10 divided into three more sections dry, moist, and wet. If the scale tips to 10 it means the soil is wettest and 1 being the driest. This type of measurement is as simple as you get.

We were looking for a meter that works well for the garden soil, and we found THZY Soil Moisture Sensor Meter is best among all. We did test many good soil moisture meters, and the readings were also accurate. But one that bugged is the time the different variants took to get the reading.
As for the built is concerned it is made of molded plastic and stem is made of sturdy metal. However, it is not corrosion resistant, so you will have to clean it every time you use it. Also, make sure you do not leave the meter in the soil like the other best moisture meter requires no battery.
5. Covery 3 in 1 – Best For Multiple Purposes
The Covery 3 in 1 Soil Moisture Meters is another meter that we loved. It is 3 in 1 meter. Hence it can detect moisture, sunlight, and pH.

6. 3-in-1 with Light & PH Test Function – Best For Measuring pH
If you have a big garden, farm or lawn, you might probably want to use more than one meter. In order to use more, you need meters that are affordable. There is nothing fancy about the meter, but it does the work. Compared to other best plant moisture indicator, it is much cheaper.
The biggest reason for using this meter for outdoor plants, or garden is that you can use it to measure light, pH and Moisture.
Buyer’s Guide – What To Consider?
To make a beautiful garden or lawn, having knowledge of moisture level is a must. In order to know about it, you require the right tool. During our research for finding the right soil moisture meters, we have learned how different factors affect it. These factors will help decide the right soil moisture sensor meter for your needs like potted plants, lawns etc. Let’s look at these factors one by one:
In terms of a digital moisture meter, you don’t require measurement to its smallest unit. It must be able to tell if the soil requires water or not. You want to learn if the soil is dry, moist, or wet. Most of the meter comes with a scale of 1-10, and the scale is divided into three sections dry, moist, and wet. So make sure while you are buying the soil moisture sensor meter, check how accurate it is. Most of the time 2-3 readings are required to get the accurate reading. So go for the soil moisture sensor meter that gives you fast readings. Jellas 3-in-1 Soil pH Meter gives one of the most accurate reading.
Sensitivity will be key if you require fast and accurate reading. Sensitivity depends on how good the sensor is. The stem of the meter is key here. You have to understand how at what depth stem detects right reading. And the way meter works is you insert it into the soil at different angle and location to get the most accurate reading. So if the sensor is sensitive enough you won’t have to change angle and location too much. Even at minimum depths, the meter will be able to provide to the right readings. Indoor-Outdoor Moisture Sensor Meter has one of the most sensitive sensor.
3. Other Sensors
In addition to measuring moisture, the moisture meter also measures light and pH level. Not all meter does that. You require a meter with two stems and light sensor. Such meters use different stem for measuring the pH. One thing that you have to make sure that scale is clear and shows the measurements correctly. With such devices, it is very easy to mix up different measurements.
If you want to measure the pH and sunlight with a meter, you can try using Jellas 3-in-1 Soil pH Meter . It is one of the best combinations of digital moisture meter, pH and sunlight.
4. Ease of Use
With moisture meter, the only difficulty you can face is the stem not going into the soil. So whatever model you plan to buy you have to understand how much it can take. There are some sturdy soil moisture meters that can be used with some hard soil. But most of them require soft or wet soil.
Before buying check with the seller and read the user manual to learn more about the stem of the soil moisture sensor meter. However, one general rule of thumb that you must remember while using the moisture meter is that you never leave the moisture meter too long in the soil. Also always clean the stem after the use.
As you will be using the meter in wet conditions, you want a device that can withstand those conditions. Most of the soil moisture meters are made out of molded plastic. The stem is either made out of steel or aluminum. Check the material of the meter you are looking to buy. Other than the materials we have described are not recommended for the meter.
How We Conduct The Tests?
For moisture meter, we had to do a lot of preparation regarding creating the right testing conditions. So, the first thing we did was to get 8 experts who have years of experience with a soil moisture sensor meter. They were able to provide us the valuable information on how the meters are used. We also learned about the parameters necessary for the soil moisture meter.
Once had enough knowledge to go on, we chose 23 different meters to our lab. The way we selected these meters was we determined the top-selling meters. For that we contacted the sellers, the helped us to identify the different variants. Also, we also made sure the brand manufacturing the meter is reputed.
Once we had different variants, we designed the tests on parameters like accuracy, ease of use, design, and sensitivity. For tests, we simulated the conditions where meter is used. We got all kinds of soils that are used of gardening, farming or for lawns. We made sure that each soil had samples with different moisture levels. Once we were ready with the conditions, we tested each model one by one and noted the results.
Beyond tests, we also wanted to listen to what the existing user of different models thought about it. Their views helped us to know how the meter performs after months or years of use. Also, there are some insight about a certain product that can be learned by testing, you need to have hands-on experience. Only the existing users have that. So we contacted them through seller and learned as much as possible. We also went through several reviews sites to see what the users are talking about the product.
After 75 hours of testing and customer feedback, we asked our team to score each model on three parameters ease of use, accuracy, and design. We calculated the overall score and selected the six soil moisture meters among all. Here is the scorecard:
