pH/EC-2681 is a multifunctional product that can measure pH and EC online in real time. It is mini portable, easy to operate, accurate in measurement, suitable for a wide range of applications and uses, suitable for fish farms, swimming pools (bathrooms), laboratories, Water treatment, schools and colleges, hydroponics, etc.
SPECIFICATONS： 1 . Range : pH 0.00~14.00, EC 0~19.99ms/cm 2 . Resolution : pH 0.01PH, EC 0.01ms/cm 3 . Accuracy : ±0.1pH, EC±2%F.S 4 . Battery : DC6V 5 . Temperature Compensation : 0°C~50°C 6 . Operating Temperature : 0°C~50°C 7 . Dimensions : 130mm×77mm×31mm 8 . Weight : 180g
OPERATING STEPS :
Remove the protective cap, connect pH electrode into relative electrode socket. Wash electrodes in distilled water, and dry it by filter paper. 3. connect to power adaptor to turn on. 4. Put pH electrode, conductivity electrode into liquid which is to be test, and stir lightly. Wait until the digital is stable，read the final value. 5. After use, wash electrodes, put on protective cap. In below situations, devices must be re-calibrated. Electrode is placed to be new ones Having been used (or placed) for a long time after calibration Electrodes are very often used High accuracy is required.
Package List :
1 * pH/EC-2681 Meter
EC CALIBRATION
1. Dip conductivity electrode into 12.88ms/cm standard buffer solution, and shake lightly. 2. When the showing value is stable, adjust by bottom “CAL” until it shows 12.88EC. Wash electrode in distilled water and dry it with filter paper. 3. Dip the device into 1413μs/cm (1.41EC) standard solution, showing value and standard solution is within error range.
CAUTIONS :
While testing please stir electrodes, and avoid the bubbles on it. Else it will affect the result. If the error is too big or EC value is not going back to 0, dip EC electrode into ethyl alcohol and shake for 5-10 seconds to wash the electrode. PH calibration 1. Immerse the electrode in pH 6.86 (under the temperature of 25℃)standard buffer solution of phosphate, and gently shake the electrode . 2. Regulate the pH7 trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained. 3. Cleaning the electrode .Immerse the electrode in the standard buffer solution of pH4.01, Regulate the pH4 trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained. 4. Cleaning the electrode. Immerse the electrode in the standard buffer solution of pH9.18 and gently stir until the display value is stable. If the error of display value is in the allowable range, then calibration is finished. If not, repeat 2.3.
