Portable 5-in-1 Water Tester, Digital PH/Salinity/Temperature/TDS/EC Meter

<br>This product has a five-in-one function, which can measure ph, tds, ec, salinometer and temperature <br>Measurable salinity (sea salt/freshwater salt) <br>Sea Salt: Seawater salinity is the ratio of total dissolved solids to the weight of sea salt in seawater, usually expressed in grams per kilogram of seawater. (Measuring range 10.1-200.0ppt) <br>Light salt: light water with salt content less than 0.5g/L (measurement range: 0.00-25.00% accuracy: 0.01-5.00% 5.10-25.00%) <br> <br>Waterproof grade: TP67 (it can still be used after falling into the fish tank) <br>replaceable probe <br>Auto Calibration Product Description <br>Product parameters <br>Conductivity test range: 0 to10000uS/cm 10.01-19.99ms 20.1-400mS/CM <br>Resolution: 1uS/cm; 0.1mS/CM <br>Accuracy: ±2% of reading <br>Tds test range: 0 to 1000ppm 1000ppm to 10000ppm 10.1 to 200.0ppt <br>Resolution: 1ppm;; 0.1ppt <br>Accuracy: ±2% of reading <br>Salinity measurement range: 0.00 to 25.00% <br>Resolution: 0.01% <br>Accuracy: 0.01-5.00% (±0.1%) 5.10-25.00% (±1%) <br>pH test range: 0.01-14.00pH <br>Resolution: 0.01pH Accuracy: ±0.05pH <br>Temperature Compensation: Automatic Temperature Compensation (ATC) <br>Working environment: 0 to 60.0°C (32.0-140°F); RH 100% <br>TDS factor: 0.4to 1.0 <br>Temperature range: 0.1-60.0℃ 32.0-140℉ <br>Temperature accuracy: ±0.5℃ <br>Temperature resolution: 0.1°C/°F <br>Auto power off: about 5 minutes 3x1.5LR44 <br>Display: Support backlight <br>Waterproof grade: IP67 <br>Power consumption: 2.9 mA, power consumption is 0 when off <br>The accuracy is relatively accurate within 150ppt, and the deviation above 160ppt is relatively large. <br>Note: After each use, be sure to clean the electrode
