This Moisture Meter gives you the moisture content of your compost pile or soil sample by means of a sensor in the bottom of the probe.
The probe is sensitive only at the tip. Calibrate the instrument by inserting the tip into a saturated sample of compost or soil and setting the needle on scale: 0 to 10. Then insert your Moisture Meter into the medium to the depth to which you wish to measure the relative moisture level.
The results will be derived instantly. Composters, farmers, landscapers, landscape maintenance, and nurseries use the Compost Moisture Meter.
Power source: one AA battery included
Probe length is 36"
Easy to calibrate for any compost or soil type

* Like all instruments, the Compost and Soil Moisture Meter should not be dropped or left in the compost or soil for extended lengths of time.**
