Technical parameter:
Measuring range: 0.0~14.0PH
Resolution: 0.1PH
Accuracy: ±0.1PH
Temperature Compensation: 0℃~50℃
Dimension: 150mm*29mm*20mm
Weight: 51g
Operation:
1. Remove the protective cap.
2. Firstly clean the electrode with distilled water, and suck it with filter paper.
3. Turn on PH meter by “ON-OFF” switch located on the top of the battery case.
4. Immerse the PH meter electrode in solution up to the immersion level. Under no circumstances immerse above display level.
5. Stir gently and wait for the reading to stabilize.
6. After use, switch off it. Use the distilled water clean the electrode and replace the protective cap.
PH calibration:
1. Immerse the electrode in PH6.86(under the temperature of 25℃) standard buffer solution of phosphate, and gently shake the electrode.
2. Regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained.
3. Immerse the electrode in PH4.01 or PH9.18 the standard buffer solution of borax.
4. After about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
Notes:
The instrument’s PH range must be re-calibrated whenever.
The electrode has been used (laid) for long time from the last calibration.
The electrode has been used in particularly taxing conditions.
The utmost accuracy is required.
Battery installation:
If the display of meter fades, to replace all the batteries. Pull out the battery case and replace the batteries. Pay attention to the polarity of battery.
Warranty:
This instrument is warranted from all defects in material and manufacturer for a period of one year from the date of purchase. If during this period, the repair or the replacement of parts is required where the damage is not due to negligence or erroneous operation by user, please return the parts to either dealer or our office, and the repair will be effected free of charge.
