Durante el compostaje o la jardinería, a menudo se puede preguntar: ¿Qué tan húmedo está tu suelo? Ahora sabrás y podrás compostar, jardín o simplemente saber si tus plantas necesitan más agua. La escala 0 a 10 del MM24 indica un relativo "húmedo" o "secador". El medidor de humedad mide la humedad en la punta de la sonda. Las instrucciones de calibración están convenientemente impresas en el lado de la cabeza del medidor e incluidas en la parte posterior de la caja. El medidor de humedad REOTEMP utiliza 1 pila AAA. Debido a que la sonda utiliza conductividad eléctrica, la presencia de sal puede afectar las lecturas haciendo que su suelo sea más o menos conductivo. Por lo tanto, el medidor de humedad REOTEMP no se recomienda para situaciones en las que el contenido de sal varía drásticamente entre muestras de prueba.

Strong can penetrate hard soil and handles help. I like that one can adjust the sensitivity of the reading to suit your soil and moisture preferences.

This is a tool that's worth the money. We are replacing our thrid cheap unit from Home Depot with this heavy duty tool. Based on build quality it should last a lifetime. The accuracy is good because they let you start out by doing a definition of what is the "just right" moisture on the meter. And since the meter is facing you it's very easy to read. We like the 24" because we don't have to stoop down to read it.Now that said we had one issue and one suggestion.After removing the tape covering the battery, the battery because dislodged (ittle did we know) so the meter was reading zero all the time. Once I opened it up and saw the batter out of the holder it was an easy fix. I presume the battery was dislodged pullling out the tape or in shipment. Easy fix.While having it open I noticed the potentiometer was very loose. A few turns tightened it up and a drop of loctite made sure it stays that way. Tip to the builder; loctite is your friend.

Purchased 4/5/2017.1. I use this at least weekly, in both the greenhouse and garden. I am changing the battery today for the first time. You need to change the battery when you no longer get wet readings in wet soil. Caveat: Do not check if the new battery is working using distilled or RO water. I used RO (ease of access) and got a reading of 6-8. I looked up the info (see pdf link below) and with tap water, more than maxed at 10.2. Do not keep this in the greenhouse. It is too wet and the mechanics will rust, the battery will rust. I have been doing this for the past 3 years (sitting on top of the grow lights), and on opening the device has some rust, but the potentiometer is working fine. There is slight rust on the battery terminals. The suggestion is a cool, dry place. I will move to the garage.

I liked it very much until the 9th use. After reading the other, I used a long bamboo stick to first create a hole in the ground in which to insert the water meter for each use. After the 9th use, in a hole in soft dirt, the tip pulled away from the stem.Husband opened the meter enclosure to pull in the black wire so the tip could be placed back on the stem. But the tip is very loose and will easily come off again. He said that the soldering for the wires is very delicate and will eventually break when the tip pulls away while pulling out of the ground.The design is bad and cheap. Husband says they need to have threads on the meter stem, the plastic insulator and threads on the tip to keep the tip in place. Also, noticed the battery is in an awkward tight spot. I liked it very much while it worked. You don't really need to calibrate it. Just use like you would one of the smaller versions you can buy elsewhere. Returning it immediately. We do not recommend.

This is a wonderful product! It's quickly become my favorite garden tool. But there is something in particular that I did not understand about how to use it when I bought it. I see now that the manufacturer's product description includes this information, but I didn't really understand it. Now I do.The manufacturer's description includes the following words: "The 0 to 10 scale of the MM24 indicates a relative "wetter" or "dryer". I missed the meaning of that at first. Once I got the meter I figured it out. The 0 to 10 moisture scale is not in some type of universal moisture units. It is a relative scale - relative to some sample soil that you have chosen to calibrate the meter to. The calibration process is easy, it doesn't take more than 2-3 minutes to do. But it is very important.There is a little screw, under a little rubber cap, on the back of the meter. This is the calibration screw. You find (or mix together) some reference sample soil that you feel has a reasonable amount of moisture contained in it for the type of plants you will be using the meter on - not sloppy wet, but not obviously too dry (I used some soil in an outside planter box to calibrate my meter to that I had just watered well and allowed to drain well). With the meter placed at least a few inches into the sample soil, you turn the screw until the meter needle reads "5" on the "0" to "10" scale. Replace the rubber cap over the screw. Your meter is now calibrated to your sample soil. These calibration instructions are actually printed in very small text on the back of the meter.When you test other soils in the future any reading under "5" is dryer than your sample was, and any reading over "5" is wetter than the sample soil was. I have concluded that any reading of between about 3 and 7 are acceptable for the plant I am checking.I think this is a brilliant system. You determine the range of wetness you want for your trees/shrubs/plants. After calibrating the meter to that reference point you are then comparing all other soils to it. If you have dramatically different types of plants (e.g. cactus vs bamboo) you might have to re-calibrate for each of those.My meter is the 24" version. When checking trees, especially two young small ones I have planted during the past few months, I have found it is important to slowly push the meter stem all the way down the 24" inches, while watching the meter during the process to get an idea of how wet the soil is at different depths. Sometimes it is pretty dry the first few inches, but by the time I get about 12" to 15" deep it is registering 8 to 10 on the meter. So I know not to water yet because the tree's root ball was planted 24" deep. Other times it is pretty wet the first few inches from lawn watering, but only registering 2 or 3 on the scale at deeper levels, so I know it is time to water it.
