5 in 1 PH meter water quality tester TDS/EC/PH/salinity/thermometer digital water quality tester

Multi-functional water quality tester EZ-9909 is a new multi-functional water quality test instrument, which can measure pH, TDS,EC, salinity value and temperature. The measurement range is large and wide, which can measure both fresh water salinity and sea salt Usage and calibration procedure as well as usage precautions Noted:Always clean the electrode after use If the pH calibration cannot identify the solution, the electrode is broken Product Description EC Measuring range: 0 to10000uS/cm 10.01-19.99ms 20.1-400mS/CM Resolution: 1 uS/cm; 0.1 mS/CM; Accuracy: ±2% of reading TDS Measuring range: 0 to 1000ppm 1000ppm to 10000ppm 10.1 to 200.0ppt Resolution: 1ppm;; 0.1ppt Accuracy: ±2% of reading Salinity Measuring range: 0.00 to 25.00% Resolution: 0.01% Accuracy: 0.01-5.00% (±0.1%) 5.10-25.00% (±1%) PH Measuring range: 0.01-14.00pH Resolution: 0.01pH Accuracy: ±0.05pH Temperature range: 0.1-60.0℃ 32.0-140℉ Calibration: Conductivity EC: Supports 3-point calibration automatic identification (1413us 12.88ms and 111.8ms) with 3 calibration points (1413uS/cm 12.88mS/CM 111.8mS/CM) pH: 1 point (6.86) or 2 points (6.86 4.00) (6.86 9.18) or 3 points (6.86 4.00 9.18) can automatically identify the calibration solution Size and weight:183*37*37mm(7.2*1.5*1.5in)/90g(3.2oz) Packing List 1*5 in 1 tester 1*manual in english 3*ph buffer power
