Operating Instructions:
-
Turn on the meter.
-
Immerse the electrode in the
-
solution to be tested.
-
Stir gently and wait for the reading to stabilize.
-
Press the “”C/”F”key,choice the C/”F for measuring.
-
Press the”EC/pH”button,choice the PH or EC for measuring.
-
After use,turn off the meter.
-
Rinse the electrode with distilled water to minimize contamination.
-
Always replace the protective cap after use.
Note:
EC meter value is the reading×10.
Example:the reading display to 128,actual EC meter value for:128×10=1280us/cm
Calibration:
1)PH
-
Rinse the ph electrode first with distilled water,and suck it with filter paper(not included).
-
Turn on the meter.Press the”EC/pH”button,choice the PHfor measuring.
-
lmmerse the ph electrode in pH 6.86(0r pH7.00)buffer solution:gently shake the meter and wait
-
for a stable display.
-
Regulate the trimmer with the Screwdriver provided until display shows”6.86″(“7.00)at buffer solution temperature of25℃.
-
Rinse the ph electrode with distiled water,and suck it with filter paper(not included)
-
lmmerse the pH electrode in DH4.01 or pH9.18(pH10.0) buffer solution,gently shake the electrode and waiting for the reading to stabilize.The showing value and buffer solution’s ph value is within
-
error range.
-
The calibration of the instrument’s pH range is now complete.
Important:
-
The ph meter should be recalibrated under following situations:
-
The meter has been used for long time since the last calibration or use.
-
The meter has been used in particularly continual conditions.
-
The utmost accuracy is required.
2)EC
-
Turn on the meter.Press the “EC/pH”button,choice the EC for measuring.
-
Immerse the electrode in the distilled water.Activate it about five minutes.
-
Immerse the electroder in 1413uS/cm calibration solution.And stir it gently.
-
Unscrew the battery compartment cap on the top of the meter.
-
Allow the reading to stabilize and with a small screwdriver turn the calibration trimmer until the display shows”141(141×10=1410)
-
Rinse the electrode with distilled water and suck it with filter paper.
-
Immerse the electroder in 150uS/cm calibration solution.gently shake it and wait for a stable display.The showing value and buffer solution’s value is within error range.
-
Rinse the electrode with distilled water and suck it with filter paper.
-
The calibration of the instrument’s EC range is now complete.
