Frequently Asked Questions

Does this meter need batteries?

No - the 2-way meter is self-powered and requires no batteries.

What do the 0-10 scales represent?

On the moisture scale, 0 represents dry and 10 represents very moist. On the pH scale, 0 represents highly acidic and 10 represents highly basic (alkaline).

Can this be used for outdoor plants as well?

Yes - the 2-way meter is suitable for both indoor and outdoor use.

Is this meter as accurate as a digital pH meter?

This is an analog soil indicator best suited for general monitoring and watering guidance. For precise pH management, a digital pH meter with calibration solutions is recommended.
