How To Choose The Best Digital Saltwater Pool Tester?
Testing Ability
Chemical levels should be maintained in the following ranges for a well-balanced saltwater pool:
- Calcium Hardness: 180-200 ppm
- Stabilizer level: 50-80 ppm
- Alkalinity: 70-80 ppm

The best digital saltwater pool tester is the one that can figure out all the chemical levels. So, our experts recommend opting for a model with a wide testing ability.
Readout accuracy
Unfortunately, some digital pool water testers are not as accurate as they promise to be, despite their reputation for pinpoint precision.
To weed out the incorrect information, you should ask your friends and family members if they have any suggestions for pool service, and buy from a well-known brand.
In addition, have a look at customer reviews of the goods you've narrowed down.
Display
Digital saltwater pool testers are created to eliminate the hassles of visually comparing your findings to a color chart to find out the different chemical levels. Therefore, be sure that you pick a model with a large and easy-to-read display.
