Product Information
Specifications:
- Model: DN
- pH Calibration Range: pH 6.8
- Buffer Solution: Standard pH 6.86
Product Usage Instructions:
Calibration Process:
-
Rinse the pH probe with distilled water before
calibrating. -
Immerse the sensor in standard pH 6.86 buffer solution and stir
to expel bubbles. -
Wait for CAL1 to flash, then look for C 6.8 to appear.
-
When pH 6.8 and C 6.8 flash together, briefly press the button
to confirm. -
Display PAS 6.8 indicates successful calibration.
Post-Calibration:
After calibrating with pH 6.8, remember to rinse the pH probe
with distilled water before testing.
Additional Notes:
-
Ensure to rinse the probe with distilled water after
calibration and before testing. -
During calibration, long-press the button to power off to avoid
automatic shutdown after 3 minutes of inactivity. -
If the device displays Err due to inactivity, hold the button
to re-enter calibration mode.

CALIBRATE MODE: Enter Calibration Mode When pH is Inaccurate Step1: Prepare
the standard pH 4.0 and pH6.86 Buffer Solution (Sold Separately) Step2: Set
the sensor to pH calibration mode. a. With the device on, hold the button for
more than 5 seconds to enter calibration mode (ignore the shutdown ). b.
Immerse the sensor in standard pH 4.0 buffer solution and slowly stir,
expelling all the bubbles from the bottom. After CAL1 flashes, wait for C 4.0
to appear. When pH 4.0 and C 4.0 flash together, briefly press the button to
confirm. Display PAS 4.0, indicating successful calibration 1.
c. Before calibrating with pH 6.8, rinse the pH probe with distilled water. d.
Immerse the sensor in standard pH 6.86 buffer solution and slowly stir,
expelling all the bubbles from the bottom. After CAL1 flashes, wait for C 6.8
to appear. When pH 6.8 and C 6.8 flash to gether, briefly press the button to
confirm. Display PAS 6.8, indicating successful calibration 2.
e. After completing the pH 6.8 calibration, rinse the pH probe with distilled
water before use Notice: a. After calibration, have to rinse the probe with
distilled water before testing. b. During calibration, long-press to power
off, or it will automatically shut down after 3 minutes of inactivity,
displaying “Err”. Hold the button again to re-enter calibration mode.
