Specifications:
Range: 0.00~14.00PH Resolution: 0.01PH Accuracy: ±0.1PH Battery: 4×1.5V (AG-13) (not included) Temperature Compensation: 0℃~50℃ Operating Temperature: 0℃~50℃ Dimensions: 175 x 50x 25 mm Weight: 51g
Operation :
1. Remove the protective cap. 2. First clean the electrode with distilled water, and suck it with filter paper. 3. Turn on PH by “ON-OFF” switch located on the top of battery case. 4. Immerse the PH meter electrode in solution, Stir gently and wait for the reading to stabilize. 5. After use, Switch off it, Use the distilled water clean the electrode and replace the protective cap.
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.
Important :
A.The instrument’s PH range must be recalibrated whenever:
1.The electrode has been used (laid) for long time from the last calibration.
2.The electrode has been used in particularly taxing conditions.
3.The utmost accuracy is required.
B. Battery install
1.If the display of meter fades, to replace all the batteries, Pull out the battery case and replace the
