Measuring Range: EC: 0~10000us/cm, 10.01~19.99ms/cm, 20.1~400ms/cm， Accuracy: ±2%： Salinity:0.00~25.00%; Accuracy: 0.01-5.00% (±0.1%) 5.10-25.00% (±1%) TDS: 0~10000ppm, 10.1~200.0ppt; Accuracy: ±2% Temperature: 0.1~60.0 , 32.0~140 ; PH: 0.01~14.00PH; Accuracy: ±0.05pH ORP: 0~+/-999mV; ±2mV S.G.: 1.000~1.222 Calibration Steps: 1.Turn on meter by pressing ON/OFF button 2. Dissolve each buffer solution in 250 mI of distilled water 3. Immerse the electrode into the pH 6.86 solution. (under the temperature of 25) 4. Press the "TEMP/CAL" (calibration) button for 5 seconds and release - Display will start flashing 6.86 - Wait until the display stops flashing. 5.Then Clean the eletrode by ringing it in distilled water, dry it with filter paper 6. Immerse the electrode in pH 4.00 solution, - Press "TEMP/CAL" button for 5 seconds , screen show 6.86 then press and release immediately second time .,screen will display 4.00 . - Reading will start flashing 4.00. - Wait until display stops flashing Rinse and dry the electrode with distilled water as before. 7.Immerse the electrode in pH 9.18 solution, wait few seconds until the display is stable - Press "TEMP/CAL" button for 5 seconds , screen show 6.86 , then press and release immediately second time , screen will display9.18 - Reading will start flashing 9.18. - Wait until display stops flashing Rinse and dry the electrode with distilled water as before. ▲Operation Steps 1.Remove the protective cap. 2.Clean the Electrode with distilled water and wipe clean the spare water. 3.Press the "ON/OFF" button .Turn on the meter. 4.Immerse the PH meter electrode in the solution 5. Lightly shake the meter, read the data when the numeric stabilized. The temperate displays at the bottom of the screen . ● Press "Hold"button to lock the data . ● Press the "ON/OFF" button to shut off the instrument Clean the electrode with pure water , cover the electrode protective cap
