Operating temperature: 0-60°C

Lifespan: approx. 500 hours

Dimensions: 15.5 x 3.1 x 1.8 cm

Calibration Method:

1. Press on/off to turn on the power.

2. Dissolve each buffer solution in 250 ml of distilled water.

3. Immerse the electrode in the pH 6.86 solution (at a temperature of 25°C).

Press the "CAL" button for 5 seconds and release.

The display will start flashing 6.86

The display will stop flashing and show "End"

Rinse the electrode with distilled water and dry it with filter paper.

4. Immerse the electrode in the pH 4.01 solution (at a temperature of 25°C). Press the "CAL" button for 5 seconds, then press and release it immediately a second time. The display will begin flashing "4.01". The display will stop flashing and show "End". Rinse the electrode with distilled water and dry it with filter paper. (The 2-point calibration is complete.) 5. Once the calibration is complete, place it in the solution of known value to be detected. If the displayed value is within the error range, the calibration is accurate and can be used normally. If there is an error, repeat the calibration.
