Product Description

Reotemp Compost Moisture Meter 

Lengths available from 61cm up to 183cm

The REOTEMP Moisture Meter is a self-calibrated instrument and indicates the moisture content of your compost pile or soil sample by means of a sensor at the bottom of the probe.

Easy to operate:

  • Power source: one AA battery
  • Easy to calibrate for any compost or soil type
  • 0-10 scale


Compost or soil moisture is measured by inserting the probe into the soil at each location to be tested. The unit is sensitive only at the tip, therefore the reading obtained on the meter indicates the amount of moisture only at the probe tip. Now you can determine the moisture condition of your compost without having to remove any mulch or soil. Just insert the probe directly into the compost. Instantly, your MOISTURE METER will give you an accurate reading of moisture content.

How does the moisture meter works:

The stem & the tip are made of metal, there is a title plastic washer between them. This plastic washer gets pressed when you push the moisture meter in.
The unit at the head sends electronics signal through the compost which is picked up by stem. The more moisture in the pile the faster this electronic signs is traveling.


It is quite important that the calibration of the unit is performed in the same compost composition and location as that in which it will be used. Take a sample of compost which is already at your ideal moisture content, this will vary depending on what your needs are. Remove the black plug located on the back of the unit. Then insert the moisture meter so that the tip is in the centre of your sample. Place a small screwdriver in the adjustment slot and adjust to a reading of 5 on the 0-10 scale.


Sub-soil/sub-compost moisture mapping - This technique is used primarily for checking coverage and penetration of a sprinkler system. After a normal watering, take readings at different locations and at two or three different depths. Next, create a map plotting each of the readings. An ideal system would show equal readings at all locations and depths. Poor coverage would show erratic readings at multiple locations with the same depth. Poor penetration (or insufficient application) would be indicated by unequal amounts of moisture at the same location but different depths.

Other applications of sub-soil moisture mapping would be locating leaking water lines, checking effectiveness of septic tank leach lines, locating surface water springs, and locating depths of shallow water tables.


The battery is included and is already installed. With normal usage it should last one season. When replacement becomes necessary, (unable to obtain a meter reading of 10 in saturated soil even with Calibration Trimmer in maximum clockwise position) replace with a standard AA cell. Care must be taken to maintain correct polarity of the battery. The plus (+) side is marked on the holder.

  1. A needed tool for the garden. 3 Star Review

    Posted by on 18th Jan 2016

    The moisture meter is vey good except that the scale is very hard to set at '5' if the soil you need to watch must be quite dry. The quality is very good and I would recommend this as a useful moisture meter.
