How To Use:
Operation method:
1. Switch machine
Press and hold the power button for 1 second, the light in the upper right corner of the keypad will flash twice, and the device will turn on
When the device is turned on, press and hold the power button for 3 seconds, the light in the upper right corner of the keypad will be on, and the device will shut down
2. Turn on the backlight
Long press the return key to turn on the backlight, and then long press again to turn it off
Probe use steps:
1. Unscrew the membrane cap, rinse the electrode membrane cap and metal tube with deionized water and drying
2. Inject about three quarters of the volume of electrolyte into the membrane cap, and then tighten the membrane cap. A small amount of electrolyte overflow during this process is a normal situation. After tightening, ensure that there are no bubbles in the front of the electrode and between the electrode and the membrane. There is no liquid interval, otherwise it needs to be reinstalled
3. Connect the electrode to the opened instrument, and make the electrode polarize in the air for 1 hour
4. Test after calibration according to the electrode calibration instructions
5. When replacing the electrolyte, membrane cap or not using it for more than 24 hours, it needs to be repolarized for 1 hour
Electrode calibration:
1. Zero oxygen calibration: Pour 1 pack of reagents into about 100mL of water and stir evenly to obtain oxygen free water. Immerse both ends of the motor side in oxygen free water, and after the reading is stable (reading fluctuation is less than 0.1), perform zero oxygen calibration (zero oxygen reagent can be maintained in the air for 24 hours, and needs to be reconstituted if it exceeds 24 hours)
2. Full oxygen calibration: place the electrode measuring end in the air (suitable for general users) or immerse it in saturated dissolved oxygen deionized water with constant temperature (suitable for users with higher accuracy requirements), and wait until the reading is stable (reading fluctuates less than 0.1), perform full oxygen calibration
Package List:
1 x Dissolved Oxygen Detector With Probe (Battery Not Included)
1 x Dissolved Oxygen Electrode Tip
1 x 30ML Electrolyte
5 Pack x Zero Oxygen Reagents (5g Per Pack)
1 x Sandpaper
1 x Manual
Note:
1. When the electrode is calibrated and measured, because the electrode needs to consume oxygen, it is necessary to ensure the flow of the measuring water body (20‑30cm/s), otherwise it will cause low readings; when using, pay attention to protect the electrode membrane head to avoid contact with hard objects or pointed objects. Items, if the membrane head leaks, it should be replaced in time
2. The filling liquid in the electrode should be replaced every 20‑30 days according to the frequency of use, or the electrolyte should be replaced in time when the electrode display shows a significant deviation
3. The electrolyte and zero oxygen reagent should be stored in a dry and ventilated place at room temperature
