Temperature, moisture and pH tell you what is happening inside soil or a compost pile. REOTEMP dial thermometers read at the tip of a stainless stem 24 to 72 in. long: the heavy-duty thermometer is made for compost piles and windrows, and the fast-response thermometer, on a sturdier 3/8 in. stem, reads twice as fast; both come in °C or °F, accurate to ±1% of scale, with a probe guard and handle for tough ground. The REOTEMP soil moisture meter reads a relative 0 to 10 wetness scale at its tip and also responds to salt, so it can track leachate. For pH, the Hanna HA-99121 kit measures directly in soil (±0.02 pH), and Hanna sample preparation solutions cover 1:1, 1:2 and 1:5 soil ratios.
No, it reads relative wetness on a 0 to 10 scale. Calibrate it by setting the needle to 10 in a saturated sample of the same soil or compost, then compare readings. See our moisture meter guide.
The fast-response model reads twice as fast through a sensitive tip on a reinforced 3/8 in. stem; the heavy-duty model, on a 5/16 in. stem, is the standard for compost piles. Pick the stem length for the depth you need to reach, from 24 to 72 in.
The HA-99121 kit measures pH directly in moist soil in the field. For a lab-style result, mix the soil with a Hanna sample preparation solution at a 1:1, 1:2 or 1:5 ratio and measure the slurry.
