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 Tester 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 salinity meter 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 salinity 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.

Salinity range: 0~10000ppm/ 10.1ppt~200.0ppt or 0.01%~25.0%, Resolution: 1ppm, 0.1ppt, 0.01%
EC range: 0~10000us/cm, 10.01~19.99mS/cm, 20.1-400.0mS/cm, Resolution: 1us/cm, 0.1mS/cm
TDS range: 0-10000ppm, 10.1-200.0ppt, Resolution: 1ppm, 0.1ppt
Temperature range: 0~60°C/ 32~140°F, Resolution: 1°C/°F
Accuracy: ±2% F.S.
Automatic shutdown: 5 minutes
Note: Clean the electrode after each use

S-100 4-in-1 salinity tester
Multifunctional: This salinity meter can not only test the salt content in saltwater, but also judge the purity of water by testing TDS and EC, and supports one-click switching of salinity, EC, TDS.
Salinity mode has 3 units: ppm/ppt/%, 1%=10ppt=10000ppm, the ppm mode can measure low salinity, and the % mode can measure high salinity, which can meet the test requirements of different salinity.
ATC function: The salinity meter has a built-in temperature sensor, which can automatically perform temperature compensation to reduce errors caused by changes in solution temperature.
Portable design: The salinity meter is designed as a pen type, small in size and light in weight, easy to carry around, and with a backlight, you can clearly see the value on the screen even at night.

Salinity Meter
The higher the salt content in the solution, the lower the purity. This salinity meter has a resolution of 1ppm to help you better analyze salt in aquariums, saltwater pools, mariculture, etc.
EC Meter
Conductivity of water is a very important indicator to measure water quality. It reflects the level of electrolytes present in the water. The purer the water, the lower the conductivity and salinity.
TDS Meter
The higher the TDS value, the more impurities contained in the water, and the higher the conductivity. Both TDS and EC are important indicators to measure water quality.

3 Salt Content Units
1%=10ppt=10000ppm, the three modes of the salinity meter can meet the needs of salinity testing in different occasions.
Backlight Design
This salinity meter has a backlit LCD display so you can easily observe the test results in any situation.
Wide Applications
Our salinity tester is suitable for analyzing salt content and water quality in aquariums, saltwater pools, koi fish ponds, hydroponics, mariculture, wastewater treatment, etc.

Salinity Meter Operation Steps
Convert temperature units
Turn on the salinity meter, press and hold the HOLD/TEMP button for 2-3 seconds, the temperature unit can be switched between °C and °F.
Convert measurement mode
Turn on the salinity meter and change the measurement mode through the MODE/CAL button.
When only ppm is displayed, it is the TDS mode; when the upper left corner displays SALT, it is in salinity mode, there are 3 units of ppm/ppt/% in this mode; when it displays us/cm is EC mode.

Measurement steps:
1. Press the power button to turn on the tester. Immerse the electrode in the solution to be tested, and ensure that the whole electrode is submerged;
2. Press the MODE/CAL button to convert the tester to SALT ppm mode;
3. Gently shake the tester to ensure that there are no air bubbles around the electrode, wait for the reading to stabilize and obtain the value of the tested solution;
4. Wash the electrode with distilled water after each use and dry it with a cloth.
