Description
xThe ECOWITT WH0291 is a battery-powered soil moisture tester with a digital LCD and custom calibration that gives fast, readable moisture readings for indoor and outdoor plants.
Keep plants healthy and avoid over- or under-watering with a handheld sensor designed to give actionable moisture data in about a minute. The WH0291 combines a clear LCD console with a waterproof probe, custom 0%/100% calibration, and a compact design for use in potted plants, gardens, lawns or greenhouses.
How quickly will I know if a plant needs water?
The WH0291 delivers a moisture reading in approximately 72 seconds so you can act the same day you test. The digital console shows an easy-to-read flower pot icon and numeric moisture level so there's no guesswork.
- Typical response time: ~72 seconds per measurement
- Immediate visual cue via LCD icon and numeric readout
- Handheld probe for spot checks across multiple pots or beds
Can I trust its readings for different soil types?
Yes — the meter includes a custom mode with user-set 0% and 100% calibration points so you can adapt it to sandy, loamy or heavy soils. Calibrating for your substrate improves accuracy and makes readings comparable across different planting media.
- Custom 0%AD and 100%AD calibration settings
- Calibration compensates for soil texture and compaction
- Useful when switching between potting mixes, native soil, or raised beds
Is this sensor suitable for both indoor and outdoor use?
The probe is waterproof, allowing reliable use in outdoor gardens, lawns and indoor pots without worrying about brief exposure to moisture. The console requires a single AA battery and the probe has its own battery, keeping electronics separated and easy to maintain.
- Waterproof probe for outdoor and greenhouse use
- Separate power: console and probe each use one AA battery (not included)
- Compact, portable form factor for spot checks anywhere
What else does the display show that helps daily care?
The digital LCD presents not only moisture percentage but also a friendly flower-pot icon that visually indicates moisture status at a glance. You can switch between 12/24-hour time display modes on the console, making it convenient to timestamp checks.
- Clear numeric moisture values plus illustrative flower pot icon
- 12/24-hour time display for routine monitoring
- Console layout designed for fast interpretation during rounds
