## Overview

The Reotemp 36 Inch Garden and Compost Moisture Meter features a durable metal probe with a 36" reach and a thick 5/16" diameter for deep, reliable moisture readings. Powered by an included AAA battery, it offers a customizable 0-10 wetness scale calibrated to your soil or compost, making it an essential tool for precise watering and soil health management in gardens, farms, and compost piles.

## Description

The REOTEMP MM36 Moisture Meter allows you to measure relative moisture deep within a large compost pile. The meter indicates the moisture content of your compost pile or soil sample by means of a sensor at the bottom of the probe. The probe is sensitive only at the tip. Calibrate the instrument by inserting the tip into an ideal sample of compost or soil and adjusting the needle to a “5” on the 0 to 10 scale. Then, the next time you insert your Moisture meter you’ll know relative to your ideal moisture content whether your soil is too dry or too wet. Note that this is not a % moisture content. The meter is sensitive to changing salt content and can be used to track leachate. Used by composters, farmers,municipal composting operations, and nurseries across the country. This product is covered under a 1 year limited warranty.

Review: Quality, solid, construction - 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!

Review: This Thing Flat Out Works! - 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!

### ⭐⭐⭐⭐ Works Well.. for multiple Uses
*by J***P on April 26, 2013*

I got tired of the always break Home Depot/Lowes models made in China. This is made by Reotemp a high end industrial supplier based out of California. They sell more robust version of this product which I think are made in the USA. This one was made in communist china. I took it apart and while the quality of the components was pretty good, the mfg was not and the calibration screw was not mounted properly but I could still access it and use it. These device use galvanic current action which trips a electromagnet and requires a coarse calibration to use. The Calibration directions are not correct. You should use a two point calibration. First stick the device in water and make sure it reads above full scale and the meter is pegged. Next take a known soil source that you have water thoroughly, such as a pot you have dripped through thoroughly and is truly wet. Then stick the probe in and make sure it reads full scale by adjusting the calibration screw if required. Then take some dry potting soil or other very dry soil and make sure it reads near zero. The mfg sells direct to the public and has wireless versions. These are primarily used, I think for testing commercial compost piles although those use a longer probe. You cant keep this out 24/7 but you can check your compost soil and most soil. The case and probe are pretty rugged but your not going to be able to use it to check hard clay soil due to the fragile electromagnetic. I use it for checking my compost pile but mainly for checking the 200 or so potted plants and numerous garden beds that use compost based soil. You should be aware if you have salty soil this probe will read a higher water content than you have. Real moisture sensors are called tensiometers and cost hundreds of dollars. This is a deal for 35 dollars and the quality should give you a decade or more of use if you don't pound it into the soil. Infinitely better than the made in china garbage you can get at Home Depot or most gardening stores which simply does not work well and dies in short order.
