This meter requires a moist soil medium to function correctly. It will not provide accurate readings in pure sand or very loose, dry materials that lack sufficient moisture contact.

No, you should remove the probe and wipe it clean after every use. Leaving it in the soil for extended periods can cause corrosion and damage the metal sensors.

On the 4-in-1 digital model, you can easily toggle between temperature units using the dedicated button on the back of the device to suit your personal preference and needs.

If the soil is too dry, the meter may not register a reading. Sprinkle some water on the area and wait thirty minutes before testing again for accurate data.
