## In the box

- Meter \(1\) (Included)

- AAA batteries \(8 stated\) (Check selected pack): Contents list states 8\*AAA, while product details say four AAA batteries are included. Confirm the quantity.

## A good fit for

- Hydroponic growers who want pH, EC, TDS and temperature readings together.
- Users who value a replaceable probe and supplied pH calibration solutions.

## Less suited to

- Buyers who need a stated measurement-accuracy tolerance, since none is provided in the listed specifications.
- Anyone who requires a confirmed battery quantity before ordering without checking the selected listing.

## Customer feedback

Customer feedback highlights perceived accuracy and reliability, along with appreciation for calibration solutions and ease of use. These comments may matter for routine hydroponic checks, where the listed simultaneous pH, EC, TDS and temperature display reduces mode switching. They are customer perceptions, not a measurement guarantee, and the listing provides no accuracy tolerance.
- Positive themes: Customers describe the meter as accurate and reliable.
- Positive themes: Feedback mentions the supplied calibration solutions and ease of use.
