YIERYI 5 in 1 Salinity/ TDS/ EC/ Specific Fravity of Seawater/ Water Quality Tester

【Large Capacity Battery】Use 3V (CR2032) battery for power supply, durable, easy to replace, can be seen everywhere. (without battery).

【High-Precision Probe】The high-sensitivity alloy probe is used to avoid the interference of the magnetic field in the water, reduce errors, and effectively prevent the probe from being damaged during transportation.

【Automatic Temperature Compensation】Temperature will affect the reading level, this tester has a better temperature range of 0°C-50°C, automatic temperature compensation can ensure you get more accurate readings.

【Application Range】Professionally measure EC, TDS, SALT, S.G.
temperature. Suitable for home drinking water, hydroponics, laboratory, aquarium.

Steps:
1. Remove the protective cover. Turn on the meter.
2. Rinse the electrode with distilled water and dry the electrode with filter paper.
3. Immerse the electrode in the test solution.
4. Stir gently and wait for the reading to stabilize.
5. Short press the "MODE" key to select the measured value of EC/TDS/SALT/S.G/TEMP.
6. Turn off the meter after use. Rinse the electrode with distilled water to reduce contamination.
7. Replace the protective cap after use.
Toggle Temperature Mode: Short press the "TEMP/CAL" button to toggle between Celsius and Fahrenheit.
