Care Guide

Keep Your Meter in Top Condition.

A well-maintained probe will last for years. These are simple tools, and they ask very little of you—just a bit of attention after each use.

After Each Use

Remove the probe from soil immediately after reading. Do not leave it in for more than a few minutes.
Wipe the probe clean with a dry cloth or paper towel. Remove any soil residue from the metal surface.
If the probe has contacted fertilized or treated soil, wipe it with a lightly damp cloth, then thoroughly dry before storing.

Storage

Store your meter dry, away from direct sunlight and humidity.
If your meter came with a protective sleeve, use it. It will protect the probe tip from bending and the dial face from scratches.
Do not store in a humid shed, greenhouse, or bathroom cabinet.

Calibration

Our meters are factory-calibrated and covered by a lifetime calibration guarantee. If you notice the needle sticking, reading inconsistently, or not returning to zero, contact us and we’ll make it right.

To test your meter at home: insert the probe into a glass of water. The reading should rise to 9 or 10 within a few seconds. If it does not reach at least 8, your probe may need cleaning or recalibration.

What to Avoid

Do not submerge the meter body (dial housing) in water.
Do not use the probe in frozen or completely bone-dry soil—it can stress the sensor.
Do not bend or force the probe. If it meets resistance in the soil, remove it and try at a different angle.
Do not use abrasive cleaners or steel wool on the probe surface.
