Working environment

1. Ambient temperature 5-40 degrees

2. Relative humidity: ≤85%

Use and maintenance and precautions

1.Before the test to remove the electrode protective cover, (solution within the 3.3mol / lKCL, if the crystallization of exudation, is a normal phenomenon, does not affect the electrode use)

2.Observe the inside of the sensitive bulb is full of liquid, such as the discovery of bubbles, the electrode should be gently swinging down (like rejection thermometer) to clear the bubble within the sensitive bulb, otherwise it will affect the test accuracy.

V. electrode and PH meter matching correction and testing

1.Connect the PH electrode to the input of the PH instrument and connect it correctly.

2.According to the instrument manual for calibration, calibration results to be measured.

Electrode preservation and maintenance

1.Electrode using the gap, please clean the electrode with distilled water, the dry into the protective bottle, to be injected into the solution before the next test activation.

2.If the electrode is not used for a long time, it should be rinsed clean, dry residue of distilled water.

3.The sensitive glass bulb at the front of the electrode can not contact the hard object. Any breakage and scuffing will cause the electrode to fail.

4.Electrode electrode after long-term use, the slope of the electrode and the response speed can be reduced.Can be measured electrode in 4% HF in 3-5 seconds or diluted HCL solution 1-2 minutes, Solution soaked to make it complex

5.In the tested container, if the material is easy to pollute the sensitive ball or block the liquid, the electrode will be passivated, the response speed will be slowed obviously, the slope will be decreased or the reading will be unstable. So, the appropriate pollutant should be selected according to the nature of the pollutant. The contaminants and the appropriate cleaning agents are listed in the table below

Contaminants

detergent

Organometallic oxides

Less than / M hydrochloric acid

Organic lipid substances

Dilute soap or detergent

Resin, polymer-like substances

Alcohol acetone ether

Protein blood cell pellet

Acidic enzyme solution

Dye-like substances

Dilute bleaching solution hydrogen peroxide

6.Where the need to measure the organic solvent can dissolve polycarbonate resin, please use the PH composite electrode glass shell type electrode (such as 65-1 composite electrode)

7. Supporting instruments (the following instrument models can be used)

PHS-3C / PHS-3E / PHSJ-3F / PHSJ-4 A / PHB-4 / PHS-25
