Flyouth Water Quality Monitor Tester for Hydroponics/Aquariums/Pools/Drinking Water, 5 in 1 Digital TDS Meter with TDS/Salinity/EC/S.G/Temperature Function(with Backlight)

It is a new multi-functional water quality test instrument, which can measureTDS,EC, salinity value S.G and temperature. The measurement range is large and wide, which can measure both fresh water salinity and sea salt. Specification EC: Range:0 to 10000uS/cm 10.01-19.99mS 20.1-400mS/CM Resolution: 1uS/cm; 0.1mS/CM; Accuracy: 2% F.S TDS: Range: 0 to 1000ppm 1000ppm to 10000ppm 10.1 to 200.0ppt (oovert range automatically) Resolution: 1ppm; 0.1ppt Accuracy: 2% F.S Salinity: Range: 0.00 to 25.00% Resolution: 0.01% Accuracy: 0.01-5.00% (0.1%) 5.10-25.00% (1%) S.G: 1.000-1.222 Calibration: EC: Three points calibration optional (1413uS 12.88mS 111.8mS ) Temp Compensation: ATC Operation Environment:0 to 80.0C (32.0-176F); <90% TDS Factor: 0.5 Temp. Range: 0.1-80.0C 32.0-176F Temp. Accuracy: +0.5C Temp. Resolution: 0.1C/ F Auto shut off: 5 minutes Battery: Low battery indicator Screen size: 28*17mm Size/ Weight: 159*34*16mm(6.31*1.3*0.6in)/60g(2.1oz) Operation 1. Turn on the meter by pressing ON/OF, remove the protective cap, put it into the solution to be tested, and shouldn't over the immersion line. Then shake it slightly in water several times to get rid of air bubbles around the electrode and read the correct measurement value after the value is stable 2. Press MODE/CAL will enter into the different models, the unit of TDS is PPM or PPT, the unit of EC is uS or mS, the unit of salt is %?the unit of seawater specific gravity is S.G. 3. Press HOLD/TEMP, will display on the top left corner of the screen, it means the value has been held, then take the meter out of the solution and read the value, press HOLD/TEMP again to exit the hold mode. 4. Press HOLD/TEMP long time, the screen will switch between C and F
