11. Please calibrate with the buffer solution before useApplication:1.Most laboratory, ecological sutdies and other applications.2.Water and wasterwater treament. Electroplating rinse tanks. Drinking water,3.Hydroponics. Aquaculture. Aquariums and fish farms. Swimming pools.
Operation:
1.remove tne protective cap.2.first rinse the electrode with distilled water, and suck it with filter paper.3.turn the meter on by pressing the on key.4.immerse the ph meter electrode in the solution to be tested.5.stir gently and wait for the reading to stabilize.6.after use. rise the electrode with water to minimize contamination. turn the meter on by pressing the off key.7.always replace the protective cap after use.Calibration:
1.immerse the electrode in PH6.86(under the temperature of 25°C ) 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 ph 4.01 or ph 9.18 the standard buffer solution of borax.4.after about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
important : the instrument's ph range must be re-calibrated whenever.1.approximately one month has passed from the last calibration.2.the electrode has been used in particularly taxing conditions.3.the utmost accuracy is required.Battery installIf the meter can not be switched on or the display fades, to change batteries, pull out the battery case and replace batteries. Pay attention to the polarity of battery.WarrantyThese instruments are warranted from all defects in material and manufacturing 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 repair will be effected free of charge.
