<p>describe</p> <p> </p> <p>Blue color</p> <p> </p> <p>Size: 183*37mm</p> <p> </p> <p>5 in 1 Water Quality TesterDigital pH tester can monitor TDS, pH, salinity, EC meter and temperature measurement. TDS measurement range: 0-200,000 ppm, EC measurement range: 0-200,000 US\/cm, PH measurement range: 0.01-14.00 pH, salt water meter measuring range: 0.00-25.00%, temperature conversion function.</p> <p> </p> <p>High AccuracyThe high precision algorithm chip and electrode of our digital water pH tester ensure a precise and fast response. When the measurement is stable, just press the HOLD\/TEMP key to lock the measurement and take it out to view it, it's very simple.</p> <p> </p> <p>Two salinity metersThe pH- digital meter can detect the salinity of edible salt. At the same time, it can detect the salinity of sea water. Food Salinity Measurement Range: 0.00 to 25.00%, seawater salinity measurement range: 10.1-200.0ppt</p> <p> </p> <p>Auto-off Function \u0026 Large ScreenThe PH tester has a backlit LCD screen, which helps you see the measurement results clearly in all conditions. situations. Auto power off function can cut off the power after 5 minutes, saving energy without any operation. A fully transparent liquid crystal (LCD) is used to display the 4-digit value and the corresponding quantity physical unit.</p> <p> </p> <p>Automatic Temperature Compensation Temperature may affect the reading level, the range of the digital hydroponic pH meter is 0C to 60C (-0 to 140F), automatic temperature compensation can guarantee you the best reading, so you can test in any environment with confidence.</p> <p> </p> <p>Waterproof Grade: TP67 (it can still be used after dropping into the aquarium)</p> <p> </p> <p>Replaceable probe</p> <p> </p> <p>Auto calibration</p>
