Specifications:

1. 4-in-1 function, which can test PH/TDS / EC/salinity/water temperature to ensure the safety of drinking water.

2. The pocket-sized design is convenient to carry out.

3. The clear green backlight design allows you to read the digital test in low visibility.

4. High accuracy pH tester to ensure the accuracy of measurement.

5. Automatic temperature compensation and automatic calibration.

Note: Please calibrate the device for the first time.

Please calibrate the device for the first time, pH must be calibrated, TSD does not need to be calibrated.

The device must be recalibrated in the following cases.

1. The device has been used or left behind for a long time after calibration.

2. The electrodes are particularly widely used.

3. The measurement accuracy is particularly high.

4. Do not press "CAL" for a long time, otherwise the device will need to be recalibrated.

Replace the battery.

1. If the display value is blurred or not displayed, the battery can be changed.

2. When replacing the battery, open the battery cover and pay attention to the polarity of the battery. (Open the battery compartment, you need to recalibrate).

Automatic 2-point calibration

1. Pour the entire pack of standard 6.86, 4.00 and 9.18 buffer solutions into various clean cups.

2. To allow accurate calibration, divide the standard 6.86 solution into two cups, one for flushing the electrode and the other for calibration, so that contamination of the standard buffer solution can be minimized.

3. Press the ON/OFF button to turn on the device.

4. Insert the electrode into the standard buffer solution of PH6.86 and shake lightly until the display value is stable.

5. CAL calibration button for 3 seconds (in the 6.86 solution), together with the 6.86 auto-calibration state (the device can automatically detect PH4.00 and PH6.86 standard buffer solution), with the pH pen value is stable (error range of earth 0.02), 6.86 calibration is completed; 6.

6. Clean the electrode with distilled water or water and use filter paper to soak up the water on and around the electrode, place it in the PH4.00 standard buffer solution and shake lightly. Wait for the display value to stabilize.

7. Press the CAL calibration button for 3 seconds to start the calibration mode (in 4.00 solution), and then press the CAL calibration button for 1 time, along with the 4.00 standard state to make the PH pen value stable (error range of 0.02), 4.00 calibration is complete.

8. PH pen calibration is complete, take the unknown solution to test; Note: When the calibration is 9.18, you need to press the calibration button for 3 seconds to enter the calibration mode, and then press the calibration button for 2 consecutive times to enter the 9.18 calibration mode to the pH pen value is stable (error range of 0.02), 9, 9, 18 calibration is complete.
