Overview
A grower checking soil, coco or rockwool gets a pen-style digital pH meter that is water resistant and comes with a probe cover. A storage cap and a battery are packed with it.
Reading pH directly in soil or growing media is the job here, with calibration kept simple. The accuracy claim comes from the title. Calibration solutions, the exact calibration steps and probe life are not described.
Who it's for
Indoor gardeners and hydroponic growers who check pH by hand at the plant. Those who need continuous tank monitoring, or an outdoor-rated tool, need different equipment.
Pros and cons
- Water resistant body
- Easy calibration per the title
- Probe cover and storage cap
- Indoor use only
- Single battery required
- Calibration solution not listed
Performance notes
The probe tip touches the soil or growing medium directly, and the display reads the pH to a tenth. Calibration is the step that makes readings trustworthy, and the probe cover and storage cap protect the tip between uses.
