# MEXYBE 4-in-1 TDS Water Meter

The MEXYBE 4-in-1 TDS water meter measures TDS, electrical conductivity and temperature in Celsius or Fahrenheit. Its backlit LCD, hold and auto-lock functions are intended to make spot checks easier, while mixed customer feedback about accuracy makes it better suited to tracking changes than treating a reading as a complete water-safety assessment.

## At a glance

- Measures TDS, EC and temperature in Celsius or Fahrenheit according to the listing.
- Backlit display, manual hold, automatic reading lock and two-minute auto-off are described.
- Listing says it is factory calibrated and includes ATC.
- A TDS chart is said to be printed on the meter, with a further data sheet in the instructions.

## Pros

- The listed TDS, EC and temperature functions cover routine comparison checks for household water, RO/DI systems, aquariums and hydroponics.
- Backlighting and a hold function can help when reading or recording a result at the water sample.
- The seller describes automatic locking after a short stabilization period and automatic shutoff to conserve battery.

## Cons

- TDS and EC readings do not by themselves identify particular contaminants or establish that water is safe to drink.
- Customer feedback reports mixed experiences with accuracy, so avoid relying on a single reading for decisions requiring precise measurements.

## Before you buy

- The title says 0-9990ppm, while the detailed specifications state 0-9999 ppm. The detailed accuracy claim is ± 2% F.S, while the product details differ on dimensions and weight from the parcel listing, and the listing describes the display both as a backlit LCD and an LED screen. Confirm the selected version's exact specifications before purchase. A TDS reading is not a comprehensive contaminant or drinking-water safety test. For use, immerse between the marked lines, stir gently, then allow the reading to stabilize and lock as directed.

## A good fit for

- People comparing water readings over time, such as before and after an RO/DI filter.
- Aquarium or hydroponics users who want a handheld TDS, EC and temperature spot-check tool.
- Home users who value a backlit display and a held reading for recording results.

## Less suited to

- Anyone needing identification of specific contaminants or a complete drinking-water safety test.
- Users who require independently verified precision or a laboratory-grade measurement.

## Customer feedback

Customer feedback highlights ease of use, readability and usefulness for comparing water readings, while reports about accuracy are mixed. Those experiences make the meter potentially handy for routine comparisons, but buyers who need dependable precision should treat its readings cautiously and seek a more controlled testing method.
- Positive themes: Customers describe it as easy to use and handy.
- Positive themes: Feedback praises readability and the ability to notice differences between readings.
- Mixed feedback: Customers have mixed opinions about accuracy.

## Frequently asked questions

### What does this meter measure?
The listing describes TDS, electrical conductivity and temperature readings in Celsius and Fahrenheit. It does not describe a comprehensive test for specific contaminants.
### Can it help check an RO or DI filter?
It can compare TDS readings before and after filtration. A reading alone does not establish overall water safety or identify particular substances.
### How is a reading taken?
The instructions say to immerse the meter between its marked lines, stir lightly to remove bubbles, and wait for the result to stabilize and lock before recording it.
### Are the range and physical specifications consistent?
No. The title gives 0-9990ppm, while detailed text gives 0-9999 ppm. Product dimensions and weight also differ from the parcel details, so confirm the version's specifications.
