PEN PH METER

PH Range: 0.00 ~ 14.00 PH

Temperature Rage: 0 ~80 C

Accuracy:

1. pH: +/- 0.02 PH (*After calibration)
2. Temp.: +/- 0.8C/ +/- 1.5F

Calibration:

1. Prepare 4.01 and 7.00 or 10.01 pH buffers. Use 7.00 pH buffer for the mid-range buffer first. The pH values for the buffers are given for 25C. If the sample temperature is not 25C, the pH values displayed for the buffer will reflect the correct pH value for the sample temperature. If the electrode is dry, submerge it in distilled water for 10 minutes before calibration. Ensure that the calibrating buffers are fresh.
2. Press ON/OFF key to turn the meter on, submerge the probe in the buffer while stir gently. Then keep it still until a stable reading is reached. Press CAL for 3 seconds until the Text “CAL” appears. Then release CAL, the meter will identify the current buffer value automatically, and display 7.00 in the LCD. The result will be saved while the text “SA” displayed after 2 seconds. The meter will back to measuring mode after 1 second while text “End” showed.
3. if text “End” is showed after press CAL, it means the calibration buffer is not fresh or the probe is aging.
4. Do not take out the probe from the buffer until text “End” is showed in the LCD.
5. Same steps as calibrating pH 4.01 and 10.01.
