Your cart is empty.The REOTEMP Garden and Compost Moisture Meter is a heavy-duty moisture meter used by gardeners, composters, farmers, and nurseries to get a relative moisture level reading. The moisture meter's unique calibration feature allows it to be used in a variety of applications including compost, gardening and soil moisture testing. Calibration allows for adjustment of the meter to the specific moisture needs of different plants and applications when compared to a non-adjustable meter.

I have been using my Reotemp moisture meter for 1 month now. I am mostly impressed with its construction, solid metal case, and robust, thick, non-bending probe. I bought this meter for those reasons as the other available moisture meters have very flimsy probes that end up bending and breaking when placed in the soil to take readings.We have a new home and have done a lot of costly landscaping, plus put in a tomato/ vegetable garden and monitor our water needs daily. Our soil has a high clay content, so in some areas drains poorly, so in some instances one can easily overwater-- so a decent moisture meter is an essential tool. The Reotemp's probe extends 15", so you can measure down in the root area of most plants, for accurate readings.The meter has a quality, easy to read basic scale that gives you relative moisture meters (not % of moisture). First you set it up, and set it to a previously watered area to give you a relative reading of satisfactory moisture. This is all relative so you have to set it up to what you consider a healthy/plant soil moisture condition. The meter readings our easily adjusted with a screw driver. I set mine to six on the scale, so there is room to read over or under moisture conditions. Everyone probably will use their own criteria.The first few days I tested it against other meters I had and it was always accurate and dependable for a good reading.The probe is probably 1/4" + thick, and has no problem getting down into fairly compacted plant medium.It certainly is making gardening a lot easier for me taking daily readings-- as I don't like to water to a schedule, but rather, water when a plant actually needs it.I recommend the Reotemp meter!Joseph

Very happy with the moisture meter. Works exactly as it's supposed to work. It's a simple relative measure meter. Nothing fancy about it. Well constructed. I expect it to last for many many years without issue.

It has a thick, 5/16 inch, strong probe that can be pushed deep in the ground without bending or breaking. I had more than one other probe product before that had small, short probes that were always bending and ultimately breaking. With this 15 inch probe I can get down into where the roots should be going to be sure it is not too dry or wet. In my case it turned out deep down was too wet and killing my plants. The short probes I used before could never get more than 4-5 inches in the soil and showed optimum moisture but only near the surface. Unfortunately you have to calibrate it yourself based on what you think is an optimum moisture level. I am only a casual gardener so i do not know what optimum moisture looks like in the dirt so it was very difficult for me to calibrate. If you are a more knowledgable gardener who knows what optimum moisture looks like in the soil, I think you will like this meter because of the good strong, long probe.

Don't waste your money on any soil moisture meter that brags "No battery required." Those meters are insensitive and inaccurate. They'll tell you nothing about the moisture content of your soil. This meter - REOTEMP Garden and Compost Moisture Meter (15 Inch Stem) is worth the extra $20. It takes a battery, and you have to adjust the calibration with a small screw in the side of -the meter. I wet some soil in the yard and tested it. I adjusted the scale to read between 8 and 10. Dry soil reads about 2. Now I know how any soil in my yard (or in a flower pot) compares. The stem is also long and strong, larger in diameter than the cheaper versions. Worth every penny!

I bought seven several year old cherry trees in 5 gal containers and immediately transplanted them into 35 gal containers. With summer coming on I was concerned I might not water them enough and that in reaction I might overwater them. I set up an automatic watering system where the main variables were when, for how long and how many times per day to water them. The moisture meter worked right out of the box and I quickly discovered the soil was extremely saturated near the container sides and bottom, (9 on the scale) but much drier near the root ball (2 - 3 on the scale). I changed the flow pattern to correct this, getting a uniform 4 to 5 reading every where. It didn't take long with the moisture meter to determine the trees liked a reading of 4 on the scale and I set the watering to start their day between 4 and 5, with two early morning waterings, going down to around 3 late in the afternoon before a single watering in the evening to bring it back up to 4 for overnight to keep them comfortable even though not growing then. When I found the surface area was much dryer (2 to 3) than halfway down, (the potting soil in the containers is nearly 14 inches deep) I obtained some large chip size cedar shaving mulch, and the surface moisture came up to the 4 moisture value they really seem to thrive on. The trees have added 14 inches of new growth, nearly tripling in leaf abundance in the five weeks since I got them and I am certain that this is in no small measure due to using this Moisture Meter with its 15 inch probe to find the moisture level the trees like, and be able to easily monitor and maintain it. Kudos ReoTemp! My cherry trees are sailing towards Cherry Blossom Time big-time thanks in large part to your really excellent Moisture Meter that has worked perfectly in my deep potted soils application!! In rating features, absolute Accuracy is not something I could measure, but repeatability of measurement reading, relative Accuracy, for given soil moisture levels is excellent in my uniform soil type application for sure. I am thankful I got it, and most importantly, my cherry trees are thankful too!

Out of the box the meter is already usable (about right for my indoor plants) without calibration. Compare to other cheap soil meters that I've used before, this one is definitely well/over built. The only thing that I don't like it is the battery compartment, after removing the 4 screws, you'll find the battery holder at the back, not easily accessible. It should be rearranged and place in the front.

NO SIRVE !!!!! En primer lugar las instrucciones dicen: remover cinta roja Y NIO HABÃA TAL CINTA. Después dicen calibrar usando la muestra de suelo húmedo. Lo hice y NO RESPONDE, intenté varÃas veces a diferentes humedades y la aguja en el indicador siempre está entre 2y4, NI SE MUEVE, ni se puede calibrar.ME LI DEBEN CAMBIAR!!!!

Despite other reviews saying that they're a waste of time. I found it Very useful in recording my lawn moisture content over a wide area. The instructions say calibration is required when first using (using The screw), but experimenting I found that it was fine straight from the box.

Aún cuando seguà las instrucciones del vendedor para hace la calibración, las lecturas son muy variables para un mismo sitio, la misma profundidad. a mi no me sirvió como auxiliar para decidir cuando regar y cuanto regar el pasto. Las lecturas no son consistentes y el criterio para hacer la calibración es subjetivo

Love this moisture meter. Accurate and easy to use. Worth every penny and gives a nice piece of mind. No more wondering if the soul is wet or not and way above the cheapo ones at home depot. Look forward to buying 3 more and recommending this to every grower and gardener i know. Love it and thank you Reotemp.
