Best Soil Moisture Meter, pH Meter and Light Meter 3-in-1

The best soil moisture meter plus pH level and light sensor

Let’s get right to the point. We wholeheartedly recommend the Jellas 3-in-1 Soil Tester Kit with Moisture, pH Value and Light Sensor. From our research and experience using it we feel it is the best soil moisture meter on the market.

The gauges to check soil moisture range in price from about $10 to over $200. The average gardener or houseplant enthusiast does not need an overly expensive meter. Many of the lower priced meters are accurate for their intended purpose.

If you plan to buy a soil moisture meter it is good to consider price, the testing module, sensor readings, probe reviews and how does it work.

The Jellas 3-in-1 Soil Tester Kit is very easy to use, tests soil moisture meter accurately and displays the readings quickly. It is well built and does not require a battery.

Most people find it a great convenience to use a soil moisture meter for potted plants. After repeated use you will learn how much and how often to water plants.

Use a Plant Soil Moisture Sensor with Succulents

The soil for almost all succulents needs to be completely dry before you provide more water. It works fairly well to just stick your finger in the soil to test it. Nevertheless, with a large plant crowding a pot and some cacti it may be a challenge to stick your finger in the soil without making a mess or without getting pricked by a thorn. A soil moisture meter makes this job much easier and more accurate.

It always amazes me how many people complain that they just can’t seem to keep houseplants or outdoor plants alive. When their plants die or start looking terrible, showing signs of stress, they simply purchase some new ones. Most of the time, the only problem with their plants, is the watering routine. They have either over watered or under watered. That’s it! Then why not spend a small amount of money and purchase a device like the Jellas 3-in-1 Soil Tester Kit.

Think of it as investing in “My Plant Health System” and take the guesswork out of watering your plants. The soil moisture meter will essentially tell you if it is time to water or not. That is a valuable thing to know if you want your plants to thrive.

Over watering a plant may lead to root rot. Under watering may result in shriveled leaves and a drooping lifeless looking plant that will eventually die.

Accurate information about water, soil and light will ensure stronger, healthier and more beautiful plants! They will also live longer when taken care of correctly.

What are the Benefits of a pH Meter?

For many plants the pH level of the soil does not make a big difference. Some plants, however, including some succulents, are sensitive to acidity or alkalinity of the soil. For these plants to grow and develop at their best it is important to ensure, right from the start, that the soil has the right pH balance and that it remains at the ideal level.

Providing the correct soil pH for your plants will enable them to fully benefit from nutrients in the soil. Often it is mistakenly assumed that just adding fertilizer to a stressed plant will quickly and easily remedy the problem. If the pH levels are unbalanced that will only exaggerate the problem. If the pH is unbalanced the plant may not even be able to absorb the fertilizer. The simple quick solution is to use a plant pH sensor to test pH conditions and then make the necessary soil adjustments or add fertilizer.

With the Jellas pH Tester (built into the 3-in-1 pH Soil Meter Kit device) you will not need to use test strips or other complicated methods for testing pH levels of the soil. All you do is insert the probes and then view the pH meter reading in the indicator window. There are many pH meter guides online that will give you the optimum range for your particular plants.

What are the Benefits of Light Meters?

There are only three keys to growing great plants – the right amount of water, the right soil and finally the right amount of light. Many plants will tolerate too much or too little light. Notice we said “tolerate.” If you want your plants to thrive you need to be concerned about the correct type and amount of lighting.

Does your plant prefer direct or indirect lighting? Does it prefer a lot or a little light? Does it do better with sunlight or will it also do fine with indoor lighting? A light sensor will help you find or even know how to manipulate the lighting conditions to provide the best environment for your plants.

Where can I buy a soil moisture sensor kit?

Plant soil sensor gauges can be found at Lowes, Home Depot, Ace Hardware, True Value, Walmart, Menards and on Ebay. We found the best deal for the top moisture sensor, Jellas 3-in-1 Soil Tester Kit on Amazon.

How We Chose The Best Soil Moisture Meter

We did a lot of research to find what we consider the top soil moisture sensor. We wanted to purchase a new one for ourselves that would be accurate and would last a long time. Honestly, quite a few of the gauges look like they are made by the same manufacturer and just labeled with a different brand. That is fine but it did make it a challenge to know if we were actually comparing differently made units. The moisture meter we chose is manufactured by Jellas Ltd which is the same as the brand name it is labeled under.

There were a few soil moisture sensors with good consumer ratings but they had less than a dozen or so reviews. The one we settled on had the highest ratings with the number of reviews in the hundreds.

What Brands of Soil Moister Meters Did We Research?

We investigated all the current brands on the market including the Covery 3-in-1 Soil Tester, Dr. Meter Moisture Sensor Hydrometer, YKS 3-in-1 Soil Moisture, light and pH / acidity Meter Plant Tester, Indoor/Outdoor Moisture Sensor Meter, Szxhf Moon City 4-in-1 Soil Moisture Sensor Meter, Luster Leaf 1820, Rapitest Soil Moisture Meter, Soil pH Moister Meter, and the Mosser Lee Soil Master Moisture Meter.

How to Use the Jellas Soil Moisture Meter

It is very easy to use this lightweight soil moisture gauge. First simply choose the test function you want to use by switching the meter to MOIST, LIGHT or PH. Next insert the probes into the soil until you reach the roots. Now you just wait for up to 10 minutes for the most accurate reading. Finally, simply wipe the probes clean for use on the next plant.

Jellas 3-in-1 Kit Frequently Asked Questions

How long are the soil moister probes?

The probes are 7 inches long.

What types of plants can you use this with?

This soil moisture meter can be used with any type of indoor houseplants including succulents and bonsais. It can be used in large or small pots and with terrariums and dish gardens. It can be used outside with any plant including vegetables, herbs, flowers, shrubs and grass. Our only caution would be that we do not recommend this soil moisture meter for trees. The probes simply cannot penetrate deep enough to give you helpful data.

How long does the soil moisture tester take?

If you are in a hurry you can use the reading that appears within seconds. The instructions that are included state that for the most accurate results it is best to wait for 10 minutes. Some people with multitudes of plants purchase several gauges so they can test more than one at a time. We, however, find that just one meter fills our needs just fine.

If the soil is wet will it still work?

Yes, it will give an accurate readout even if the soil is rather wet.

Will this measure the pH of water?

No it will not. All of the various brands we investigated measure the pH levels only of the soil but not of the water you will be using. For the majority of plants the pH level of the water is not as critical.

Where is it made?

It is made in China.

Does the meter need batteries?

No, thankfully this does not need any batteries.

Can the gauge be left in a potted houseplant?

No, it should not be left in the soil. It should be removed after you check the readings. Leaving it in soil for a long time may eventually damage the probes which will cause it to give inaccurate readings. It is best to remove the probes from the soil and wipe them clean after every use.

Can I test the moisture at different depths or levels?

Yes. You can insert the probes just a few inches to get a reading and then insert them farther down for another test.


We are very satisfied with our 3-in-1 Soil Tester Kit that we purchased. It is part of our regular plant maintenance and if we ever need to purchase another meter, it will be our first choice.
