WARRANTY 

The meter is warranted to be free for one year from the date of purchase. (Electrode and battery are not included) 

This  warranty  covers  normal  operation  and  does  not  cover  battery,  misuse,  abuse,  alteration,  tampering,  neglect, 

improper maintenance or damage resulting from leaking batteries. Proof of purchase is required for warranty repairs. 

Warranty is void if the meter has been opened. 

NOTE 

1.

 

Please operate the meter Under the guidance of professionals. 

2.

 

Soak the electrode into the distilled water or purified water for 5 – 30 minutes to activate before use. 

3.

 

Please use the standard buffer solutions for pH calibration, and operate it by the calibration steps shown above. DO 

NOT press CAL key in NON calibration mode, it may cause the calibration Error. 

4.

 

The pH buffer powder should be fully dissolved in water (250ml). 

5.

 

In  calibration  mode,  the  electrode  should  be  submerged  in  the  buffer  solution.  Especially  pay  attention  to  the 

Electrode fixed collar if it is loosen when calibration, it may cause the buffer solution enter the inside of the meter. 

How to make pH buffer solution 

There are 3 pH buffer powder supplied with the meter

 when you buy them, each powder 

should be Fully dissolved in 

water(250ml). DO NOT use the metal containers. 

Take the formulation of pH 6.8 buffer solution for example:   

1. Put the pH 6.86 buffer material (in the green sachet) in a jar (the volume should be no less than 250ml).   

2. Fill the jar with 250ml distill water. 

3. Place a glass stick in the solution, swirling it until the white powder dissolved. 

4.    Store the buffer solution in the cool and dry place. Attach a label on it for further use. 

5. For the further calibration, Ensure that there is a constant supply of fresh buffer solution in contact with the probe. 

Discard the solution after use. 

The way of the formulation of other buffer is same like that . Please mark it clear and prepare to use it for the 

future. 

The use of standard buffer

 

The buffer solutions (250ml) can be used several times by divided into portions which should be kept in a cool and dry 

place(20

-25

).  Never  reuse  the  used  portion.  The  electrode  should  be  fully  covered  by  buffer  solution  when 

calibration.
