GIDIGI GX-1EU 5-in-1 Pool pH and Salt Meter

Salt Meter: The GIDIGI GX-1EU combines pH, salinity, TDS, EC and temperature measurement for pool and other water checks. Its colour display is claimed to show selected readings together, and the listing says it includes calibration solution and spare batteries. Treat its measurement claims as manufacturer specifications rather than independently verified accuracy.

Frequently asked questions

What does the GIDIGI GX-1EU measure?

The listing describes pH, salt, TDS, EC and temperature measurement.

Can it show more than one reading at a time?

The manufacturer says its colour screen displays selected combinations, including pH with salinity, pH with TDS, or EC with pH. It also says pH and temperature are always displayed.

Are batteries included?

The listing says batteries are included and the contents list specifies four extra AAA batteries. It does not clearly resolve whether operating batteries are also supplied, so confirm the package contents before ordering.

Does the listing give a recommended pool range?

It states 7.2-7.8 pH and 2700-3400 ppm salinity for pool water. These are listing recommendations, not evidence that the meter measures those ranges accurately.
