## Description

Yewhick Digital Salinity Tester for Saltwater, Waterproof Pool Salt Tester, 4 in 1 Salt/EC/TDS/Temp Meter, High Accuracy Saltwater Tester with ATC for Saltwater Pool, Aquarium, Koi Fish Pond

## Features

- 4-in-1 Salinity Tester: With salinity, TDS, EC and temperature testing functions, this saltwater tester can analyze water quality more accurately, quickly and reliably. Ideal tester for saltwater pools, saltwater aquariums and sewage treatment.
- salinity Meter with Large Range: 0~10000ppm/10.1~200.0ppt/0.01%-25.00%, greater salinity testing range brings you a better experience, and this salinity tester has an automatic temperature compensation function(32°F~140°F), which can reduce the error caused by the change of solution temperature.
- TDS and EC functions: The TDS value represents the total amount of dissolved solids in the water, while the EC represents the ability of the solution to conduct current. In general, the higher the EC value, the higher the salt content, the higher the TDS, and the more impurities in the water; conversely, the lower the EC value and TDS value, the purer the water.
- Backlit Design: This pool salt tester is designed with a green backlight, so you don't need to worry about not seeing the value on the screen in low light. You can clearly see the measurement results even at night. It will automatically shut down after 5 minutes of inactivity.
- Wide Applications: This salt pool water tester has the test functions of salinity, TDS and EC for a wider range of use. It can not only detect the salt content, such as edible salt, sea salt, saltwater pool and saltwater aquarium, but also analyze water quality by testing TDS and EC. The lower the TDS and EC values, the purer the water.
