Warm tips

It STEP 1: Turn open pH meter, Clean the electrode in distill water

It STEP 2: Immerse the electrode in pH 6.86 standard buffer solution

It STEP 3: Press the "CAL" button. Wait until the display digital is 6.86pH and steady

It STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution

It STEP 5: Press the "CAL" button. Wait until the display digital is 4.00pH. Then complete pH 4.00 calibration

It STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH

Instructions for use of PH calibration powder:
Calibration powder: pH standard solid substance. It can be used after adding water. Suitable for the calibration of any type of ph meter. Each package can prepare 250ML standard solution.

(Be sure to add water according to the required ratio, otherwise it will affect the accuracy of the calibration and increase the error)

Precautions:
Please note that the PH pen probe is a glass product and is a fragile product. Please do not collide with things. Once the damage is not replaceable, you must protect the probe. After use, use absorbent paper to gently absorb the water on the probe.

Matters needing attention:
PH meter has been calibrated before delivery, the buyer does not need to re-calibrate after receiving the goods!

In the following cases, the PH meter must be re-calibrated:
1. Has been used for a long time after calibration;
2. Special electrode use Frequently;
3. The measurement accuracy requirements are relatively high.

Standard configuration：
1XPH meter with opp bag

2X LR44 Button batteries
3X calibration powder
